大型方坯初轧辊研制并应用耐磨合金堆焊获得成功,1988年3月23日通过部级鉴定。大型初轧机开坯使用的初轧辊寻求较高的耐磨性和热疲劳性能,是国内外初轧厂面临的一项重大技术课题。在我国热轧堆焊技术目前处于恢复尺寸和提高轧 Large billet initial roll developed and applied wear-resistant alloy surfacing success, March 23, 1988 through ministerial identification. It is a major technical issue that the primary rolling mill at home and abroad is facing to seek the high wear resistance and thermal fatigue performance of the primary rolling mill. Hot-rolling surfacing technology in our country is currently in resumption of size and increase rolling
