In this paper, chemical composition is designed according to the using properties for first middle roller of sendzimir mill, technology research of Cr5 type has been done in aspect of steelmaking, refining, forging and heat treatment and so on.

Simulation and analysis of intermediate table with insulation cover;

Simulating and Analyzing of Intermediate Table Insulation Technology in Hot Continuous Rolling;

Study on the breakage of intermediate roll in SG18-H Mill;

End contour of intermediate rolls for a UCMW cold tandem mill

Rolls' deformation and roll force distribution between rolls on a six-high mill are calculated by influence function method to study the influence of single-taper crowned intermediate rolls on the roll force distribution between rolls and transverse distribution of strip thickness.
