介绍马弗式燃油钢丝加热炉的改造。通过对现有炉体关键部位的改造 ,降低了炉头的温度 ,出炉钢丝的横向温差由 80℃降为 2 5℃ ,炉膛压力分布更加合理。有效地保护了炉头处的砌体 ,可延长使用寿命 ,提高了产品质量 ,钢丝合格率提高 5 %。改造所用的投资少 ,适合同类热处理炉的改造 Describe the transformation of the muffle fuel wire heating furnace. Through the transformation of the key parts of the existing furnace, the temperature of the furnace head is reduced, the lateral temperature difference of the baked wire is reduced from 80 ° C to 25 ° C, and the pressure distribution in the furnace is more reasonable. The utility model effectively protects the masonry at the furnace head, prolongs the service life and improves the product quality, and the qualified rate of the steel wire is increased by 5%. Transformation of the investment used less suitable for the transformation of similar heat treatment furnace
