摘要
阐述了钨-铼型（WRe3-WRe25）热电偶用于炼钢连铸中间包钢水连续测温的实验。采用外保护管与热电偶分体组装方式测温。结果表明钨铼偶采用填充固体细粉制成实芯偶，其寿命可达30h以上，外保护管寿命达8～10h，热电偶寿命范围内测量精度1％T。响应时间τ0.9≤90s。
The experiment of Wre3-Wre25 Continuous thermocouple aren;t to molten steel in tundish has been related. The thermocouple life is up to more than 30h. Its life-span sustains 8~10h. The temperature response time τ0.9 of this sensor is 90s, and its precison is 1%T.
