一、前言 1982年底,抚顺钢厂结合大修改造,将原有步进式炉改为少氧化加热炉,并于83年3月16日正式投产运行。经过近三年的生产实践,证明该炉改造所采用的各项技术措施是先进的、可行的。达到了生产效率高、单耗低、成材率有明显提高的预期效果。抚顺钢厂薄板分厂步进式加热炉,原来采用高压喷射式烧嘴,由 First, the foreword By the end of 1982, Fushun Steel combined with overhaul transformation, the original step-type furnace into a less oxidation furnace, and in March 16, 83 officially put into operation. After nearly three years of production practice, that the furnace used in the transformation of the technical measures are advanced and feasible. Reached the expected high production efficiency, low unit consumption, finished products have significantly improved the expected results. Fushun steel plant step plate furnace factory, the original high-pressure jet burner, from
