Description
技术领域technical field
本发明涉及无机非金属材料的合成技术领域，特别是用固体废弃物(铬铁合金渣、废玻璃)、石灰石、纯碱及萤石为原料合成微晶玻璃材料的方法。The invention relates to the technical field of synthesis of inorganic non-metallic materials, in particular to a method for synthesizing a glass-ceramic material by using solid waste (ferrochrome slag, waste glass), limestone, soda ash and fluorite as raw materials.
背景技术Background technique
近年来我国不锈钢生产呈迅速增长趋势，对铬铁的需求量也越来越大。同时，铬铁合金冶炼企业所面临的环境压力也日趋紧迫，尤其是铬铁合金厂固体废弃物的排放，必须要符合国家环保要求。铬铁合金厂中固体废弃物主要来源于高温生产工艺中产生的炉渣和尘泥。铬铁合金渣粘度大、熔点高，渣铁无法完全分离。一般来说，每生产1t铬铁合金大约要生产1.1～1.3t废渣；同时在铬铁合金埋弧冶炼过程中，由于元素的高温蒸发、电极孔飞溅出的废渣和装料过程中炉料细小颗粒随尾气排出还会产生约25kg的烟尘或污泥。所以能够找出清洁方法利用铬铁合金渣，并合成出具有一定附加值的材料，对于节能减排和环境保护具有很重要的作用。In recent years, my country's stainless steel production has shown a rapid growth trend, and the demand for ferrochrome is also increasing. At the same time, the environmental pressure faced by ferrochrome alloy smelting enterprises is becoming increasingly urgent, especially the discharge of solid waste from ferrochrome alloy plants must meet the national environmental protection requirements. The solid waste in the ferrochrome alloy plant mainly comes from the slag and dust generated in the high temperature production process. Ferrochrome slag has high viscosity and high melting point, and the slag and iron cannot be completely separated. Generally speaking, about 1.1-1.3 tons of waste slag will be produced for every 1 ton of ferrochrome alloy produced; at the same time, during the submerged arc smelting process of ferrochrome alloy, due to the high temperature evaporation of elements, the waste slag splashed out of the electrode hole and the fine particles of the charge during the charging process are discharged with the tail gas It will also produce about 25kg of soot or sludge. Therefore, it is possible to find a cleaning method to utilize ferrochromium alloy slag and synthesize materials with certain added value, which plays a very important role in energy saving, emission reduction and environmental protection.
国内外铬铁合金渣处理工艺归结起来，主要包括回收合金或铬精矿的工艺、循环回收利用工艺等。其中回收合金或铬精矿的工艺是采用磁选、重选等方法回收，而循环回收是用铬铁合金渣为原料生产耐火材料、造渣剂或用于水泥掺和料和铺路。由于铬铁合金渣中的残余铬矿具有弱磁性，而铬铁合金具有强磁性，因此，可以采用磁选的工艺来回收渣中的铬铁合金颗粒和残余铬矿。除此之外，国内外许多厂家和研究机构都曾研究采用重选的方法来回收铬铁合金渣中的金属，一些铁合金厂和研究人员采用循环回收铬铁合金渣，并用于生产耐火材料(不烧镁铬砖和不烧镁砖)和堵眼镁砂的替代品以及做水泥掺合料和铺路。The ferrochromium alloy slag treatment process at home and abroad mainly includes the process of recovering alloy or chrome concentrate, recycling process and so on. Among them, the process of recovering alloy or chrome concentrate is to use magnetic separation, gravity separation and other methods to recover, while the recycling process is to use ferrochrome alloy slag as raw material to produce refractory materials, slag formers or cement admixtures and road paving. Since the residual chromium ore in the ferrochrome alloy slag has weak magnetism, while the ferrochrome alloy has strong magnetism, the magnetic separation process can be used to recover the ferrochrome alloy particles and residual chromium ore in the slag. In addition, many manufacturers and research institutions at home and abroad have studied the method of re-election to recover metals in ferrochrome slag. Some ferroalloy factories and researchers have used recycling to recycle ferrochrome slag and used it to produce refractory materials (not burned Magnesia-chrome bricks and non-fired magnesia bricks) and substitutes for plugging magnesia, as well as cement admixtures and paving.
微晶玻璃是50年代发展起来的新型玻璃，它是具有微晶体和玻璃相均匀分布的材料，故又称为玻璃陶瓷或结晶化玻璃；矿渣微晶玻璃作为微晶玻璃领域中的一个重要组成部分，是以各种冶金废渣、工矿尾砂和热电厂的粉煤灰等为主要原料制备的微晶玻璃。利用工业废渣制造矿渣微晶玻璃，近20年来得到了迅速的发展。矿渣微晶玻璃具有较高的机械强度、耐磨、良好的电学性能和化学稳定性，已成为一种良好的结构材料。当前的矿渣微晶玻璃主要采用高炉炉渣来制造，这是因为高炉炉渣的化学组成比较稳定，并适应CaO-Al2O3-SiO2系微晶玻璃的要求。铬铁合金渣与高炉渣成分相近，同样可用于制备微晶玻璃材料，但是由于铬铁合金渣中高熔点物质较多，所以铬铁合金渣比高炉渣出渣温度高出500℃左右；并且铬铁合金渣中成核物质较高炉渣多，析晶过程较难控制，因此本发明从这些难点出发，成功降低了铬铁合金渣微晶玻璃制备温度，并通过配料控制微晶玻璃晶相，解决了用铬铁合金渣制备微晶玻璃材料的这些缺陷，合成了性能较好的微晶玻璃。Glass-ceramics is a new type of glass developed in the 1950s. It is a material with uniform distribution of microcrystals and glass phases, so it is also called glass ceramics or crystallized glass. Slag glass-ceramics is an important part of the field of glass-ceramics. The components are glass-ceramics prepared with various metallurgical waste residues, industrial and mining tailings and fly ash from thermal power plants as the main raw materials. The use of industrial waste to manufacture slag glass-ceramics has developed rapidly in the past 20 years. Slag glass-ceramics has high mechanical strength, wear resistance, good electrical properties and chemical stability, and has become a good structural material. The current slag glass-ceramics are mainly made of blast furnace slag, because the chemical composition of blast furnace slag is relatively stable, and it meets the requirements of CaO-Al 2 O 3 -SiO 2 glass-ceramics. The composition of ferrochrome slag is similar to that of blast furnace slag, and it can also be used to prepare glass-ceramic materials. However, since there are more high-melting point substances in ferrochrome slag, the slag discharge temperature of ferrochrome slag is about 500 ° C higher than that of blast furnace slag; There are more nucleating substances than slag, and the crystallization process is difficult to control. Therefore, the present invention proceeds from these difficulties and successfully reduces the preparation temperature of ferrochrome alloy slag glass-ceramics, and controls the crystal phase of the glass-ceramics by batching, and solves the problem of using ferrochrome alloy. These defects of glass-ceramic materials prepared from slag were synthesized into glass-ceramics with better performance.
由于铬铁合金渣成分比较复杂，关于铬铁合金渣制备微晶玻璃的相关研究很少，但为了尽快使矿渣微晶玻璃在我国的产业化，研究用铬铁合金渣制备微晶玻璃，最终确定最优制备流程及制备条件，对于铬铁合金渣废弃物的再利用有很重要的意义。Due to the complex composition of ferrochrome slag, there are very few related studies on the preparation of glass-ceramics from ferrochrome slag. However, in order to industrialize slag glass-ceramics in my country as soon as possible, the preparation of glass-ceramics with ferrochrome slag was studied, and the optimal The preparation process and preparation conditions are of great significance to the reuse of ferrochrome slag waste.

具体实施方式detailed description
采用铬铁合金渣、废玻璃、石灰石、纯碱及萤石为原料，其配比如表1所示。在1500℃～1550℃温度熔融常压保温1～4h，将制得的基础玻后通过热处理后合成矿渣类微晶玻璃材料。对合成试样进行X射线衍射分析和SEM分析。Ferrochrome alloy slag, waste glass, limestone, soda ash and fluorite are used as raw materials, and the proportions are shown in Table 1. Melting at 1500°C-1550°C under normal pressure for 1-4 hours, and then heat-treating the prepared basic glass to synthesize a slag-like glass-ceramic material. X-ray diffraction analysis and SEM analysis were performed on the synthesized samples.
表1合成铬铁合金渣微晶玻璃材料的原料配比与合成条件Table 1 Raw material ratio and synthesis conditions of synthetic ferrochrome alloy slag glass-ceramic materials
通过制备设计流程图，如图1所示,得到了不同成分配比的铬铁合金渣微晶玻璃材料，按照实验设计合成材料的X射线衍射与扫描电镜结果图分别如图2、图3所示，从图中可以看出，合成材料的主晶相均为透辉石与霞石，并且随着铬铁合金渣在原料中百分含量的增加，微晶玻璃生成晶粒的聚集成的相变小，这样直接导致微晶玻璃的机械性能(如显微硬度、抗弯强度)亦随之产生变化，如图4、图5所示。随着铬铁合金渣成分的增加，显微硬度随之增加，当铬铁合金渣含量增加到50％的时候达到104MPa；而抗弯强度先增加，后减小，在铬铁合金渣含量达到45％的时候维氏硬度达到最大值，即9859.78MPa。Through the preparation and design flow chart, as shown in Figure 1, ferrochrome alloy slag glass-ceramic materials with different composition ratios were obtained, and the X-ray diffraction and scanning electron microscope results of the synthesized materials according to the experimental design are shown in Figure 2 and Figure 3 respectively , it can be seen from the figure that the main crystal phases of the synthetic materials are diopside and nepheline, and with the increase of the percentage of ferrochrome alloy slag in the raw material, the crystal grains of glass-ceramics are aggregated into a phase transition Small, which directly leads to changes in the mechanical properties (such as microhardness and flexural strength) of the glass-ceramic, as shown in Figure 4 and Figure 5. With the increase of the ferrochrome slag composition, the microhardness increases accordingly, reaching 104MPa when the ferrochrome slag content increases to 50%; while the flexural strength first increases and then decreases, and when the ferrochrome slag content reaches 45% When the Vickers hardness reaches the maximum value, that is 9859.78MPa.
