speed of melting

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 higher speed of temperature going up and lowering and higher measuring efficiency.

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。
