内加热耐火材料锌锅在钢丝热镀锌中的应用

垂直浸入式电加热热镀锌锌锅自１９９０年在热镀锌生产线上使用至今，无任何维修；电耗由原上加热式的４３０ｋＷ·ｈ／ｔ降为１６０ｋＷ·ｈ／ｔ；锌利用率达８８％；钢丝质量和生产率均提高。提出对加热管的维护。实践证明，浸入式内加热镀锌锅是热镀锌生产的理想设备。

Application of Refractory Zinc Pot with Inner Heating forGalvanizing Steel Wire by Dipping

Since the zinc pot for galvanizing by dipping with vertical immersing type electric heating has been used in the line after 1990,it needn′t any maintenanceThe electricity consumption has been reduced from 430 kW·h/t of former upper heating type to 160 kW·h/tThe utilization ratio of zinc has reached 88%The quality and productivity of steel wire have been improvedIt is advised that the heating tubes be upheldPractices have proved that the galvanizing pot with immersing type inner heating is an ideal equipment for galvanizing by dipping production
