一、引言建国以来,我国低碳钢丝热镀锌行业大多数工厂仍沿用钢板锌锅,加热方法,初期均在锅侧烧煤,还有改为烧油或燃气的,到了六十年代使用电阻丝锅侧加热的工厂逐渐增多起来,这是因为电加热温度稳定,容易自动控制。但是,钢板锌锅能被锌液溶蚀,并生成锌铁合金渣,当温度增高时,溶蚀也随之加快,如遇到钢板局部含杂质过多或温度过高,锌锅寿
I. INTRODUCTION Since the founding of the People’s Republic of China, most factories in the low-carbon steel wire hot-dip galvanizing industry in our country still use the steel plate zinc pot. The heating method is that coal is burned at the pot side and replaced with oil or gas at the initial stage. In the 1960s, Slab side of the heating plant gradually increased, it is because the electric heating temperature stability, easy automatic control. However, the steel plate zinc pot can be dissolved by the zinc liquid, and generate zinc-iron alloy slag, when the temperature increases, the dissolution will also be accelerated, such as the case of steel plate containing excessive impurities or excessive temperature, zinc pot life
