Study on the Roller’s Thermal Stress of the Liquid Core Heavy Reduction Rolling Mill
The key technologies of heavy reduction on liquid core of thick slab rolling mill are designing the roller structure and the selection of high temperature high strength materials. This paper using finite element analysis method compared the temperature field, thermal stress field and strain field. Two material 2Cr12NiMoWV and 5Cr4W5Mo2V and two structures which is roll-sleeve and built-up welding roll in rolling process are analyzed. The results show that the 5Cr4W5Mo2V roll-sleeve type roller has advantages.
