摘要：

挤压筒加热是热挤压生产过程中的重要前提条件之一。熟练掌握不同分区接线对于设计人员和现场维护工人都非常重要。介绍了目前挤压筒加热的常用分区方式、相应的接线方式、加热功率和电流计算、电阻加热器结构、热电偶测温配置等。并且根据现场实际调试经验,提出了一些实用的建议，为今后设计更合理的挤压筒加热分区方式、现场接线及处理电气故障、编程控制挤压筒温升和温差提供了一些参考。

The container heating is one of the important prerequisites of hot extrusion. Familiar with the different zones wiring connection is very important for the designer and fieldworker. The common application of multiple zones heating container, corresponding wire connection, calculating heating power and electric current, the structure of heating resistance, the thermocouple configuration and so on were introduced. According to the actual fieldwork experience, some useful and practical advices were mentioned, which provide reference for designing more reasonable heating zones of container, wiring and electrical failure treatment on fieldwork, and programming control of container temperature.
