摘要
Abstract
The effects of stirring current intensity,superheat in tundish and second cooling intensity on equiaxial crystal ratio of 430 stainless steel slab were analyzed under the conditions of industry test.The results show that macrostructure of 430 ferritic stainless steel slab consisted of columnar grains and equiaxial crystal grains.With the stirring current intensity increasing or superheat in tundish decreasing,the equiaxial crystal ratio of 430 stainless steel slab increases significantly.Weak cooling process is advantageous to obtaining high equiaxial crystal ratio.With current intensity of 1 700 A,superheat in tundish of 20 ℃ and second cooling intensity of 0.95 L/kg,the surface wrinkling of 430 cold-rolled plates do not happen.关键词
