The mine communication cable has the characteristics of fire prevention, damp proof and so on. The reason of fire is mainly caused by overloading, short circuit, excessive resistance and external heat source. Under the fault conditions such as short circuit, local overheating and external heat, the insulation resistance of insulating materials decreases, the insulation capacity is lost, and even the fire is caused.

为了减少产渣的数量，所有浸入镀锅内的设备，如炉鼻、沉没辊、稳定辊和支架都必须采用耐Al-Zn-Si合金熔液腐蚀的材料制作，一般采用高耐热不锈钢SUS316L。热浸镀铝锌硅产生的渣子极易积在辊子表面，产生积瘤甚至将辊子包成不规则的形状，必须及时铲去。辊子两端不与钢带接触的地方以及辊颈、侧面也常有渣子的晶粒形成，有时会长得很大。与镀锌不同的是沉没辊表面一般不能有排渣的槽子，因为有槽子的辊子易在沟槽处产生积渣，也不利于铲去以产生的积瘤。
