Research on Solidification Behavior and Mold Flux Property of SCM435 Steel
According to the solidification characteristics of SCM435 steel and the basic conditions of mold flux for alloy steel,the causes of crack and cancave on slab surface were analyzed.The main metallurgical properties of mold flux for SCM435 steel were explored.The results show that the surface defects can be effectively controlled by using a flux with high viscosity,high melting point and low melting rate.This flux can improve liquid supercooling at the top of the mold,and makes the thermal conductivity of the mold walls more even.
