摘要
Abstract
Heat treatment was performed on three kinds of copper containing cast steel large test blocks with different sizes and specifications,and the mechanical properties were tested by sampling on the surface,T/4 and core positions of the test blocks.The results showed that the copper containing cast steel test block could meet the performance requirements of 300 mm and 400 mm wall thickness components after heat treatment,but the 450 mm wall thickness test block with larger size specifications showed unqualified results in performance testing.Within a certain cooling rate range,the normalizing cooling rate was helpful to improve the strength of the copper containing cast steel.The comprehensive mechanical properties with twice normalizing heat treatments were better than those of once normalizing heat treatment,and the grain size of the copper containing steel was finer after twice normalizing heat treatments.关键词
