Description
技术领域technical field
本发明属连铸技术领域，特别是提供了一种铜包铝复合材料多流高效率连铸成形设备与工艺，适用于包覆层金属熔点高于芯材金属熔点的复合材料的连铸成形。The invention belongs to the field of continuous casting technology, and in particular provides a multi-flow high-efficiency continuous casting forming equipment and process for copper-clad aluminum composite materials, which is suitable for continuous casting of composite materials whose cladding layer metal melting point is higher than the core material metal melting point .
背景技术Background technique
铜包铝复合材料是近年来发展起来的一种新型层状复合材料，是一类高性能的复合导体。它由铝芯和铜包覆层组成，兼有铜的导电性能优异、耐腐蚀性能好以及铝的成本低、重量轻等优点，主要体现在：重量比铜导体轻；电导率比铝导体高，而用作某些特殊用途的导体，如高频导线和用于传输大电流的导电排，由于其趋肤效应，其导电性能与纯铜接近甚至几乎与纯铜相同；抗拉强度比铝高，焊接性能与纯铜相近；通过控制加工工艺可以获得比较好的综合力学性能和稳定性。Copper-clad aluminum composite material is a new type of layered composite material developed in recent years, and it is a kind of high-performance composite conductor. It is composed of an aluminum core and a copper cladding layer, which has the advantages of excellent electrical conductivity and corrosion resistance of copper, low cost and light weight of aluminum, mainly reflected in: lighter weight than copper conductors; higher electrical conductivity than aluminum conductors , and used as a conductor for some special purposes, such as high-frequency wires and conductive bars for transmitting large currents, due to its skin effect, its electrical conductivity is close to or even almost the same as that of pure copper; its tensile strength is higher than that of aluminum High, the welding performance is similar to that of pure copper; by controlling the processing technology, better comprehensive mechanical properties and stability can be obtained.
已经公开报道的铜包铝复合材料的制备工艺主要有以下几种：The preparation techniques of copper-clad aluminum composite materials that have been publicly reported mainly include the following types:
第一种方法是包覆焊接法。该方法为美国开发的铜包铝复合线材加工方法，是目前国内外大多数生产铜包铝线材厂家所采用的生产工艺，其工艺流程为：铝芯线经过矫直装置矫直后，用刷洗机清除表面的氧化物，铜带表面的油脂和氧化物被清洗机和刷洗机清除，然后两者同步进入由情性气体保护的包覆区。铜带在多对滚轮的孔型作用下沿纵向逐渐卷起形成圆管状，将铝芯线包覆。然后进入焊接区用氩弧焊将铜包覆层纵缝连续焊接起来，形成铜包铝线坯。经去毛刺处理后 对线坯进行多道次拉拔，以获得所需直径的铜包铝线，并通过热处理以改善界面结合状态，赋予所需的力学性能。尽管包覆焊接法是目前国内最成熟、最稳定的铜包铝线生产方法，但其主要的不足是，由于采用氩弧焊接铜包覆层，焊接前铝芯线表面及铜带表面在加工过程中的二次污染、铜层的焊接强度、焊接时高温对铝芯线熔化的影响及焊接后线材表面焊缝的清理、焊接处铜层厚度的均匀性、铜铝层之间材料的结合强度等，不可避免地影响了铜包铝线的质量，尤其是对于超细丝的制备，构成尚难以克服的技术难题。The first method is the cladding welding method. This method is a copper-clad aluminum composite wire processing method developed in the United States. It is currently the production process adopted by most copper-clad aluminum wire manufacturers at home and abroad. The oxide on the surface is cleaned by machine, and the grease and oxide on the surface of the copper strip are removed by the cleaning machine and the scrubbing machine, and then both enter the coating area protected by the inert gas simultaneously. Under the action of multiple pairs of rollers, the copper strip is gradually rolled up in the longitudinal direction to form a round tube, covering the aluminum core wire. Then enter the welding area and use argon arc welding to continuously weld the longitudinal seam of the copper cladding layer to form a copper-clad aluminum wire billet. After deburring treatment, the wire blank is drawn for multiple times to obtain the copper-clad aluminum wire with the required diameter, and heat treatment is used to improve the interface bonding state and endow the required mechanical properties. Although the cladding welding method is currently the most mature and stable copper-clad aluminum wire production method in China, its main disadvantage is that due to the use of argon arc welding of the copper cladding layer, the surface of the aluminum core wire and the surface of the copper strip are processed before welding. The secondary pollution in the process, the welding strength of the copper layer, the influence of high temperature on the melting of the aluminum core wire during welding, the cleaning of the weld seam on the surface of the wire after welding, the uniformity of the thickness of the copper layer at the welding point, and the combination of materials between the copper and aluminum layers Strength, etc., inevitably affect the quality of copper-clad aluminum wires, especially for the preparation of ultra-fine wires, which constitute a technical problem that is still difficult to overcome.
第二种方法是轧制压接法。该方法为美国开发的铜包铝复合线材加工方法，其工艺过程为：铝芯线在铜带包覆前先矫直并在旋转式钢丝刷装置内消除表面氧化物，然后进入高频感应加热器中加热，炉内以氨气为保护气体，以防氧化；两条铜带分别用钢丝刷刷去表面的氧化层，通过两个接触轮进行接触加热，随后与铝芯线—起进入氨气保护炉中加热，在炉中可进一步消除铜带及铝芯线表面的氧化物；加热了的铜带和铝芯线进入轧辊压合机后被压合在一起。压合后的线坯再进入通有氨气的冷却管，以除去铜层表面的氧化物，使之光亮。然后经切毛边装置切除线坯两边的压合毛边，然后进行拉拔加工。该方法设备投资较大，复合工艺繁杂，需要预先制备铜薄带和铝线，显著增加了生产成本。The second method is the rolling and crimping method. This method is a copper-clad aluminum composite wire processing method developed in the United States. The process is as follows: the aluminum core wire is straightened before the copper strip is coated, and the surface oxide is eliminated in the rotary wire brush device, and then enters high-frequency induction heating. Heating in the furnace, the furnace uses ammonia as a protective gas to prevent oxidation; the two copper strips are respectively brushed off the oxide layer on the surface with a steel wire brush, contacted and heated by two contact wheels, and then enter the ammonia together with the aluminum core wire. Heating in a gas shielded furnace, in which the oxides on the surface of the copper strip and aluminum core wire can be further eliminated; the heated copper strip and aluminum core wire enter the roll pressing machine and are pressed together. The pressed wire blank then enters the cooling tube with ammonia gas to remove the oxide on the surface of the copper layer and make it bright. Then, the pressing burrs on both sides of the wire blank are cut off by the burr cutting device, and then the drawing process is performed. This method requires large investment in equipment, complex composite process, and requires pre-preparation of copper thin strips and aluminum wires, which significantly increases production costs.
第三种方法是静液挤压法。静液挤压法加工铜包铝复合线材的基本思路是，以大直径紫铜管坯和纯铝棒坯套装成复合挤压坯料(需对头部和尾部进行密封处理)，经静液挤压一次成线坯，通过大等静水压力和大加工变形作用，实现铜、铝间的冶金结合。静液挤压法的挤压筒内的粘性介质显著降低了坯料和挤压筒与模具之间的摩擦力，因而可大大改善金属流动的均匀性。但静液挤压法存在的主要问题是：(1)成形非圆形截面的双金属包复材料时需将包覆层金属和芯材金 属预加工为尺寸与模具精确配合的管材和棒材，并要对两者进行一系列表面处理，以保证复合前的“清洁”界面，工艺流程较长(见：胡捷，机械加工与自动化，2001，9：27-28)；(2)静液挤压工艺的设备复杂、设备投资大；(3)静液挤压法难以实现连续生产，非生产性间隙时间长，生产效率低。The third method is the hydrostatic extrusion method. The basic idea of processing copper-clad aluminum composite wire by hydrostatic extrusion method is to use large-diameter red copper tube billet and pure aluminum rod billet to form a composite extrusion billet (the head and tail need to be sealed), and after hydrostatic extrusion The wire billet is pressed once, and the metallurgical bonding between copper and aluminum is realized through large isostatic pressure and large processing deformation. The viscous medium in the extrusion cylinder of the hydrostatic extrusion method significantly reduces the friction between the billet and the extrusion cylinder and the die, thus greatly improving the uniformity of metal flow. However, the main problems of the hydrostatic extrusion method are: (1) When forming a bimetallic cladding material with a non-circular cross-section, it is necessary to pre-process the cladding metal and the core metal into pipes and rods whose dimensions are precisely matched to the mold. , and a series of surface treatments must be carried out on the two to ensure a "clean" interface before compounding, and the process flow is relatively long (see: Hu Jie, Machining and Automation, 2001, 9: 27-28); (2) Static The equipment of the hydrostatic extrusion process is complicated and the equipment investment is large; (3) the hydrostatic extrusion method is difficult to realize continuous production, the non-productive gap time is long, and the production efficiency is low.
第四种方法是先将铝液浇注到异型铜管中制备铜铝异型复合铸坯，然后经轧制、拉拔成形矩形断面的铜包铝母排(见：张坚华等.铜铝复合汇流排的铸锭、拉伸成型工艺及设备.中国专利：ZL200710177267.8)，这种方法主要缺点在于：(1)铜铝复合前需预先成形异型铜管并对铜管进行表面处理，增加了生产成本和环境负担；(2)铝液浇入铜管时，难以避免铜管内表面的氧化问题，导致铜铝结合界面质量下降；(3)铜铝异型复合铸坯的制备过程是非连续性的，并且单根复合坯料长度较短，加之坯料因疏松和冒口等缺陷需切头去尾，生产效率和成材率均较低。The fourth method is to first pour the aluminum liquid into the special-shaped copper tube to prepare the copper-aluminum special-shaped composite billet, and then roll and draw the copper-clad aluminum busbar with a rectangular section (see: Zhang Jianhua et al. Copper-aluminum composite busbar Ingot casting, stretch forming process and equipment. Chinese patent: ZL200710177267.8), the main disadvantages of this method are: (1) Before copper-aluminum compounding, it is necessary to pre-form special-shaped copper tubes and carry out surface treatment on the copper tubes, which increases production Cost and environmental burden; (2) When the aluminum liquid is poured into the copper pipe, it is difficult to avoid the oxidation problem of the inner surface of the copper pipe, resulting in a decrease in the quality of the copper-aluminum bonding interface; (3) The preparation process of the copper-aluminum special-shaped composite billet is discontinuous , and the length of a single composite blank is short, and the blank needs to be cut off due to defects such as looseness and risers, so the production efficiency and yield are low.
第五种方法是先采用水平连铸直接复合成形工艺(见：谢建新等.一种包复材料水平连铸直接复合成形设备与工艺.中国专利：ZL200610112817.3.)制备铜包铝复合坯料，然后再通过轧制、拉拔等工艺制备矩形断面的铜包铝复合母排(见：谢建新等.一种高性能铜包铝矩形横断面复合导电母排及其制备工艺.中国专利：ZL200810057668.4)。这种方法采用水平连铸直接复合成形法制备铜包铝坯料，可避免坯料预成形以及表面处理的问题，提高了生产效率，缩短了工艺流程，但该专利公布的方法还存在几个尚待解决的问题：一是，由于连铸复合的过程是包覆层金属铜管先凝固，然后铝液在先凝固的铜管中凝固并与铜管复合，为了控制复合的程度，连铸的速度 不能太高，一般要比单独铜管连铸的速度低一些(见吴永福等，矩形断面铜包铝复合材料水平连铸直接复合成形，中国有色金属学报，2012，22(9)：2500-2507)，一定程度上影响了连铸复合法制备铜包铝复合材料的效率。二是，铜包铝复合材料的界面层对其性能至关重要，界面层厚度和组成是决定界面层性能的关键。连铸复合成形属于固液复合，即固相铜与液相铝复合，极容易发生剧烈的界面反应，生成对界面结合强度产生不利影响的金属间化合物(见吴永福等，连铸直接成形矩形断面铜包铝复合材料界面及在轧制过程中的变化，中国有色金属学报，2013，23(1):191-200)，因此，需要对连铸过程中的铜铝复合界面进行精确控制，但现有专利没有提出精确控制复合界面的方法。The fifth method is to first use the horizontal continuous casting direct compound forming process (see: Xie Jianxin et al. A kind of cladding material horizontal continuous casting direct compound forming equipment and process. Chinese patent: ZL200610112817.3.) to prepare copper-clad aluminum composite billet , and then prepare a copper-clad aluminum composite busbar with a rectangular cross-section by rolling, drawing and other processes (see: Xie Jianxin et al. A high-performance copper-clad aluminum rectangular cross-section composite conductive busbar and its preparation process. Chinese patent: ZL200810057668.4). This method adopts the direct compound forming method of horizontal continuous casting to prepare the copper-clad aluminum billet, which can avoid the problems of billet preforming and surface treatment, improve production efficiency, and shorten the process flow. Problems to be solved: First, since the process of continuous casting compounding is that the cladding metal copper tube solidifies first, and then the molten aluminum solidifies in the first solidified copper tube and is compounded with the copper tube, in order to control the degree of compounding, the speed of continuous casting It should not be too high, generally lower than the continuous casting speed of a single copper tube (see Wu Yongfu et al., Direct composite forming of copper-clad aluminum composite materials with rectangular cross-section, Chinese Journal of Nonferrous Metals, 2012, 22(9): 2500- 2507), to a certain extent, it affects the efficiency of copper-clad aluminum composite materials prepared by continuous casting composite method. The second is that the interface layer of the copper-clad aluminum composite material is very important to its performance, and the thickness and composition of the interface layer are the key to determine the performance of the interface layer. Continuous casting composite forming belongs to solid-liquid composite, that is, solid-phase copper and liquid-phase aluminum are composited, which is very prone to violent interfacial reactions and generates intermetallic compounds that adversely affect the interfacial bonding strength (see Wu Yongfu et al., continuous casting direct forming rectangular Cross-sectional copper-clad aluminum composite material interface and its changes during rolling, Chinese Journal of Nonferrous Metals, 2013, 23(1):191-200), therefore, it is necessary to precisely control the copper-aluminum composite interface in the continuous casting process, However, the existing patents do not propose a method for precisely controlling the composite interface.
