摘　　要：氢氧火焰切割技术,上世纪迅速应用到连铸坯的火焰切割领域,取得了较好的经济与社会效益。近年该技术由不断火切割发展为断火切割,与原技术相比至少节约65%的能源消耗,同时设备寿命延长,维护维修工作量减少,工作环境得到改善,降低了工人的劳动强度,具有更好的经济社会效益。Oxyhydrogen flame cutting technology was rapidly applied to the cutting of continuous casting billet in the last century,which achieved good economic and social benefits.In recent years,oxyhydrogen flame cutting technology has developed from a constant flame cutting to the intermittent cutting.Compared with the original technology,the later can save not less than 65%in energy consumption,extend equipment life at the same time,reduce the maintenance workload and the labor intensity of workers,and improve working environment.Oxyhydrogen flame intermittent cutting technology has better economic and social benefits.
