摘　　要：本文对双热丝法测量保护渣结晶过程和结晶率装置的组成及试验过程进行了详细介绍。该测定装置用两根双铂铑热电偶丝分别既作加热元件又作测温元件,可以分别控制温度,可以任意调整双丝的距离,具备在线观测渣膜两边不同温差情况下的结晶过程和结晶面积大小。该装置具有升、降温速度快,测量效率高的特点。对板坯保护渣在结晶器内的特性研究具有十分重要的意义。In this paper, the double hot wire method for measuring device protection slag crystallization process and crystallization rate of composition and the test process in detail. The measurement device with two double platinum rhodium ther- mocouple wire, respectively, both as a heating element and a temperature measuring device, can control temperature respectively, can adjust the distance of the double wire, have online observation on both sides of the flux film crystallization process under different temperature conditions and crystal size. The device has a liter, cooling speed, measuring the characteristics of high efficiency. Within the slab in the mould protection slag on the characteristics of the research is of great sig- nificance.
