Abstract: A measuring device for melting and crystallization parameters of slag has been developed using single thermal couple which not only is as a measuring temperature element ‚but also as a heating element with the characteristics of ℃ for crystallizing temperature also was ±10℃ and the error for crystallizing rate of slag was ±5％．

摘要： 研制了热丝法炉渣熔化和结晶参数测定仪,该测定仪用一根双铂铑热电偶丝既作加热元件又作测温元件,具有升、降温速度快,测量效率高的特点。对板坯保护渣测试结果表明,炉渣开始熔化温度和流动温度的测量误差±10℃,结晶温度±10℃,结晶比率±5%。
