1. Jinjin cast steel adopts Huashu CAE casting simulation software to conduct solidification simulation, analysis and demonstration on the archway according to the initial process to complete the optimization of casting process and ensure that the rolling mill archway has no shrinkage cavity, no shrinkage porosity, compact structure and good comprehensive mechanical properties;  

2. The advanced cast steel adopts metamorphic treatment and argon gas blowing technology at the bottom of ladle to strictly control the quality of liquid steel, reduce the content of gas and harmful elements in liquid steel, improve the purity of liquid steel, so as to ensure the quality of rolling mill arch;  

3. Advanced cast steel adopts special heat treatment, which greatly enhances the wear resistance and impact resistance of rolling mill arch, prolonging the service life of rolling mill arch;  

4, Qianjin cast steel has strong production strength of cast steel parts, can produce large quantities of rolling mill arch and other parts, short casting cycle, large output
