The following aspects were studied on the Geleeble3500 thermal/force simulation tester: 1. Thermoplasticity of materials and simulation of continuous casting process; 2. 2. Rolling process simulation, compressive stress relaxation test; Precision casting technology, research on austenite recrystallization law, dynamic and continuous transformation law of high grade pipeline steel and the effect of cooling rate on microstructure; 4, Effect of Nb precipitation on microstructure transformation of low carbon Si-Mn steel; 5, Effect of continuous annealing process on microstructure transformation of IF steel (containing Nb-Ti),IF steel (containing Nb-Ti) and IF steel (containing Nb-Ti); 6,TTT, static CCT, dynamic CCT and welding CCT and other welding hot pressing deformation model and performance simulation; 7, heat treatment process such as strip annealing process simulation, annealing process simulation; 8,TTT, static CCT, dynamic CCT, dynamic CCT and welding CCT hot pressing deformation process simulation. The company set bearing manufacturing, research and development, sales as one, the main production of metallurgical steel rolling, petroleum, mining, electric power, machinery, precision large cast bearings. With excellent bearing production line, advanced production technology and perfect testing means, with a high-quality R & D, the development of new products of professional and technical team, 70% of the products are exported to Europe, Southeast Asia, Africa and other places. The outer ring of the conventional bearing is installed in the bearing seat hole, and the surrounding outer ring is supported by the bearing seat, while the senjimir bearing is in direct contact with the outer diameter of other rollers, and the contact area is very small. Due to the limitation of the supporting surface, the deformation of the outer ring is caused, which changes the load distribution in the bearing and affects the bearing capacity. The bearings of domestic sengimir mill are completely dependent on imports. Because the research on the design and manufacturing technology of the small casting bearings by the domestic bearing manufacturers lags behind the well-known foreign enterprises.
