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.

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.

The pushing system is the main part of the shovel, which is used to drive the action of the shovel stick, to complete the function of extending and retracting the stick, to complete the matching and cooperation between the shovel and the truck. With the continuous progress of the refining output of our plant, the original refining furnace water system can no longer meet the demand of cooling. Through the transformation of the middle stop system, the technical parameters have been improved, and the water quantity, pressure and quality have been improved. The indoor monitoring of the water consumption point is completed, and a water supply and return system of one machine is completed. The alarm of low water quantity and pressure is given, the hidden danger of accident is eliminated, the water quantity and pressure conditioning are balanced, the problem that the water supply is greater than the return water quantity is solved, and the safe consumption of the refining furnace is ensured. Two 30 ton LF refining furnaces in Guangzhou. The finite element simulation method is used to simulate the shrinkage process of the large shrinkage shrinkage pipe, and the results are similar to the dynamic tensile test under the downhole temperature field. 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.
