摘要
Abstract
During mill supervising, cracks happened at outer arc side of heat bend made by one factory. Low melting point metal Cu was discovered in cracks through chemical analysis, microstructure analysis, metallographic analysis, SEM and energy spectrum analysis. Based on combination testing result with manufacturing process of induction heating bend, and lucubrating the reason of outer arc cracks of induction heating bend, there reaches a conclusion,Copper brittleness is easily occurred by low melting point metal Cu contamination, which is the main reason that causes induction heating bend crazed and expanded. Then offered two suggestions to prevent cracks of induction heating bend combining relevant standard and the actual production situation.关键词
