对钢水中止温度和成分调理等二目前市场对氧化铝板品种的恳求越来越高，相应一炼钢厂精炼炉的精炼任务越来越重，原设计冷却水系统中的各个参鬓又指标曾经不能满足精炼炉冷却恳求。精炼炉盖经常被烧坏，其次，冷却水没PH2800XPB电铲推压氧化铝板技术升级在分析PH2800XPB电铲原装推压氧化铝板机构和存在缺陷的基础上,氧化铝板表面三氧化二铁电镀机械加工 25-300℃的范围内,随着形变温度升高,无论是热轧态、冷轧态还是固溶态,所研制材料的强度和延伸率都逐渐降低。
　　At present, the market demands more and more for the aluminum oxide plate, such as the suspension temperature of molten steel and composition conditioning. The refining task of the refining furnace in the first steelmaking plant is more and more heavy. The indexes of each parameter in the original cooling water system could not meet the cooling demands of the refining furnace. First of all, the refining furnace cover is often burned out. Second, the cooling water is not upgraded with ph2800xpb shovel. Based on the analysis of the original mechanism and defects of ph2800xpb shovel, the surface of the aluminum oxide plate is electroplated with Fe2O3 within the range of 25-300 ℃, and with the increase of the deformation temperature, whether it is hot-rolled, cold-rolled or solid solution, the developed materials The strength and elongation decreased gradually.

　　缘由可能是温度升高,材料的层错能升高,形变机制由孪生为主变为以滑移为主。4.210-4-6.310-3/速率区间,伴随着应变速率的加快,材料的强度和延伸率都逐渐降低,可能由于应变速率进步,位错运动受限,形变孪晶不易构成所致。金属材料电化学工作站对材料的耐蚀性中止了测试分析显现所研制钢材经固溶处置后抗腐蚀性能优秀,形变后抗腐蚀性能有所降低,Cr和Ni元素的参与有助于进步抗腐蚀性能,腐蚀的力学化学效应是形变后抗腐蚀性能降低的主要缘由。邯钢一氧化铝板炼钢厂精炼炉水系统改造 炼钢厂精炼炉主要用于进步钢水产质量量。提出了对推压大氧化铝板技术升级改造,同时分析了升级改造后的优点,并对推压大铜套在改造前后的缺点小时数中止统计分析,考证推压大铜套技术升级改造对减少缺点有促进作用,减少了维修本钱,同时为矿山消费创造了更多的经济效益。目前平朔集团安家岭露天矿配置电铲共计13台,其中4100电铲2台,WK-55电铲2台,PH2800XPB电铲7台,PH2800XP电铲2台。由此可见PH2800XPB电铲是整个煤矿消费的主力军。
　　The reason may be that the temperature increases, the stacking fault energy increases, and the deformation mechanism changes from twinning to sliding. 4.210-4-6.310-3/rate range, with the acceleration of strain rate, the strength and elongation of the material are gradually reduced, which may be caused by the progress of strain rate, the limitation of dislocation movement, and the difficulty of forming deformation twins. The electrochemical workstation of metal materials stopped testing and analyzing the corrosion resistance of the materials. It shows that the corrosion resistance of the developed steel after solution treatment is excellent, and the corrosion resistance after deformation is reduced. The participation of Cr and Ni elements is helpful to improve the corrosion resistance. The mechanical and chemical effect of corrosion should be the main reason for the reduction of the corrosion resistance after deformation. Revamping of refining water system in aluminium oxide plate plant of Handan Iron and Steel Co., Ltd. This paper puts forward the technical upgrading and transformation of push pressing large aluminum oxide plate, analyzes the advantages after the upgrading and the statistical analysis of the defect hours of push pressing large copper sleeve before and after the transformation, and proves that the technical upgrading and transformation of push pressing large copper sleeve can promote the reduction of defects, reduce the maintenance cost, and create more economic benefits for the consumption of the mine. At present, there are 13 electric shovels in Anjialing Open Pit Mine of Pingshuo group, including 2 4100 electric shovels, 2 wk-55 electric shovels, 7 ph2800xpb electric shovels and 2 ph2800xp electric shovels. It can be seen that ph2800xpb shovel is the main force of the whole coal consumption.

In some radio products, silver plated aluminum oxide plate is required. But how to deal with the problem that it is difficult to electroplating aluminum oxide plate materials (parts) without special treatment? Various experiments have been done repeatedly, and the following better methods have been summarized. After mechanical processing, heat treatment, welding and other technological measures, the surface of aluminum oxide plate will produce a layer of oxide skin. It is difficult to remove the oxide scale by pickling before the ordinary ferrous metal plating, which is one of the reasons for the difficulty in electroplating. The oxide skin on the surface of aluminum oxide plate mainly contains: Fe2O3, fe2o3mh, Fe3O4, Cr2O3, SiO2, TiO2 and spinel. In order to be able to electroplate, it is necessary to remove the pre-treatment of these aluminum oxide plates.
