Abstract:Cold heading steels should have high cleanliness,good surface quality and excellent cold forming performance.This paper introduces the development and prouduction of cold heading steels in Hangzhou Iron and Steel Group Company.Smelted by LD or EAF-LF process and rolled by Morgan high speed wire rod mill. A series of cold heading steels,such as HML10,ML35 and ML40,CH35ACR and CH40ACR are produced.Their surface quality and cold forming performance are maeliorated by improving cleanliness of steel and optimizing cooling process of Stelmor line.
