Description
技术领域technical field
本发明涉及淬火工艺布局与方法，是应用于集约化热卷连续热处理线的控制技术，具体涉及一种集约化热卷连续热处理的淬火冷却均匀性控制方法。The invention relates to a quenching process layout and method, and is a control technology applied to an intensive hot coil continuous heat treatment line, in particular to a quenching cooling uniformity control method for intensive hot coil continuous heat treatment.
背景技术Background technique
针对热轧带钢热处理的淬火冷却，现有热连轧热处理线主要为板状态热处理；现有热轧热处理线冷却方式普遍采用水冷，如水幕、水喷嘴等方式或者组合；现有热轧热处理线对冷却水边中边、上下表有流量分配控制。但是，对于集约化热卷连续热处理线来说，其设备、产品、规格和工艺特点均发生了较大变化，必须采用与其匹配的新的淬火冷却模式和方法以更好的控制冷却均匀性和板形。For the quenching and cooling of hot-rolled strip heat treatment, the existing hot continuous rolling heat treatment line is mainly heat treatment in the plate state; the cooling method of the existing hot-rolled heat treatment line generally adopts water cooling, such as water curtain, water nozzle, etc. or a combination; the existing hot rolling heat treatment The line has flow distribution control for cooling water side, middle side, upper and lower tables. However, for the intensive hot coil continuous heat treatment line, its equipment, products, specifications and process characteristics have undergone major changes, and a new quenching cooling mode and method must be adopted to better control cooling uniformity and plate shape.
以下为针对现有技术中的淬火的进一步说明：The following is a further description for quenching in the prior art:
1、淬火冷却技术1. Quenching and cooling technology
随着产品工艺的不断改进，特别是在设备制造、技术应用和工艺控制方面的进步，使得冷却技术越来越重要。现有技术中采用多种冷却技术(包括喷气冷却、高速喷气冷却、气雾冷却、辊冷技术和水淬冷却等)来进行应对，以达到合理的冷却效果。气雾冷却是冷却的方式之一，它是借助压缩空气的能量，将水滴雾化并以高速喷射到物体表面，气雾冷却技术具有表面传热系数高、冷却均匀等优点。气雾冷却技术传热机理复杂，冷却介质为水与气的混合，不是单一介质，不同的水压和气压设定将影响冷却介质与带钢之间的换热系数。可以通过气水比等方式的控制来调节雾化程度、冷却能力等目的。With the continuous improvement of product technology, especially the progress in equipment manufacturing, technology application and process control, cooling technology is becoming more and more important. In the prior art, a variety of cooling technologies (including jet cooling, high-speed jet cooling, gas mist cooling, roll cooling technology, and water quenching cooling, etc.) are used to deal with it, so as to achieve a reasonable cooling effect. Air mist cooling is one of the cooling methods. It uses the energy of compressed air to atomize water droplets and spray them onto the surface of objects at high speed. Air mist cooling technology has the advantages of high surface heat transfer coefficient and uniform cooling. The heat transfer mechanism of air mist cooling technology is complex, and the cooling medium is a mixture of water and air, not a single medium. Different water pressure and air pressure settings will affect the heat transfer coefficient between the cooling medium and the strip. The degree of atomization, cooling capacity and other purposes can be adjusted by controlling the gas-water ratio.
钢的淬火——将钢件加热到Ac3或Ac1以上某一温度，保持一定的时间，然后以适当速度冷却获得得马氏体和(或)贝氏体的热处理工艺。Quenching of steel—a heat treatment process in which steel is heated to a temperature above Ac3 or Ac1, maintained for a certain period of time, and then cooled at an appropriate rate to obtain martensite and (or) bainite.
可以根据不同冷却方式的特点，选择合理的冷却方式进行淬火。According to the characteristics of different cooling methods, a reasonable cooling method can be selected for quenching.
2、淬火的应用2. Application of quenching
气雾冷却在连铸、薄带连铸等产线上中有较多应用。但由于热轧卷或板的淬火冷却特点(品种、规格等)，气雾淬火在热卷或热连轧板淬火热处理工艺领域应用较少。目前在热连轧领域，淬火仍主要以水为冷却介质，以水淬为主。Gas mist cooling is widely used in production lines such as continuous casting and thin strip continuous casting. However, due to the quenching and cooling characteristics of hot-rolled coils or plates (variety, specifications, etc.), gas mist quenching is rarely used in the field of quenching heat treatment of hot coils or hot continuous rolling plates. At present, in the field of hot continuous rolling, quenching still mainly uses water as the cooling medium, and water quenching is the main method.
3、现有技术存在的问题3. Problems existing in the existing technology
集约化热卷连续热处理线较传统热处理线带钢走速(带钢运行速度)慢、产品规格薄、均匀性要求高，这是对淬火冷却工艺影响最大的变化点，基于集约化热卷连续热处理线，原有技术存在以下问题：The intensive hot coil continuous heat treatment line is slower than the traditional heat treatment line (strip running speed), with thinner product specifications and higher uniformity requirements. This is the change point that has the greatest impact on the quenching and cooling process. Based on the intensive hot coil continuous Heat treatment line, the original technology has the following problems:
1)、现有热连轧板、卷淬火热处理工艺主要针对厚度3mm以上规格，同时厚度4mm以下规格均匀性已经较难控制，板形问题突出。而集约化热卷连续热处理线涵盖更薄规格范围(厚度可达2mm，且以厚度2-4mm规格为主)，从板形理论中我们知道，带钢规格越薄，平直度死区小，相同的应力条件下，抵抗翘曲变形的能力越小。所以对冷却均匀性更敏感，现有热处理冷却方式不能满足要求；1) The existing hot continuous rolling plate and coil quenching heat treatment process is mainly aimed at specifications with a thickness of 3mm or more, while the uniformity of specifications with a thickness of less than 4mm is already difficult to control, and the problem of plate shape is prominent. The intensive hot coil continuous heat treatment line covers a thinner specification range (the thickness can reach 2mm, and the thickness is mainly 2-4mm). From the shape theory, we know that the thinner the strip specification, the smaller the flatness dead zone , under the same stress conditions, the smaller the ability to resist warping deformation. Therefore, it is more sensitive to cooling uniformity, and the existing heat treatment cooling methods cannot meet the requirements;
2)、冷却均匀性和带钢走速直接相关，传统热处理线带钢运行速度可达75m/min，而集约化热卷连续热处理线走速更低(一般10m/min以内)，走速低会加剧冷却的不均匀性，冷却均匀性要求更高，现有热处理冷却方式不能满足要求；2) The uniformity of cooling is directly related to the running speed of the strip steel. The running speed of the strip steel in the traditional heat treatment line can reach 75m/min, while the running speed of the intensive hot coil continuous heat treatment line is lower (generally within 10m/min), and the running speed is low. It will aggravate the non-uniformity of cooling, and the requirements for cooling uniformity are higher, and the existing heat treatment cooling methods cannot meet the requirements;
3)、冷速和均匀性在一定程度上互为矛盾，需要实现在保证冷速条件下的更高的均匀性控制，这要求对冷速进行控制，现有淬火热处理模式方法已不能满足；3) The cooling rate and uniformity are contradictory to a certain extent, and it is necessary to achieve higher uniformity control under the condition of ensuring the cooling rate, which requires the control of the cooling rate, which cannot be satisfied by the existing quenching heat treatment mode;
4)、现有热处理主要为无张力状态淬火，均匀性控制手段不适用于集约化热卷连续热处理的淬火冷却均匀性控制。4) The existing heat treatment is mainly quenching in a tension-free state, and the uniformity control method is not suitable for the quenching and cooling uniformity control of intensive hot coil continuous heat treatment.
正是由于连续热处理线和传统热处理线的差异(规格、走速、张力、工艺特点等)，导致连续热处理对均匀性控制提出了更高要求。因此现有的冷却设备、方法和工艺无法适应新的要求，必须做出新的、开创性的方法和优化调整来满足连续热处理线生产质量要求。It is precisely because of the differences between continuous heat treatment lines and traditional heat treatment lines (specifications, running speed, tension, process characteristics, etc.) that continuous heat treatment puts forward higher requirements for uniformity control. Therefore, the existing cooling equipment, methods and processes cannot adapt to the new requirements, and new and innovative methods and optimization adjustments must be made to meet the production quality requirements of the continuous heat treatment line.
