为配合高炉冶炼,1985年6～10月,在包钢l~#高炉上采用插入式WRLB—600X快速微型热电偶,配用电位差计直接读数,在主铁沟沙口处及北渣口渣沟内,对出渣出铁过程中的渣铁温度进行点测和连测。连测是从铁水流过沙口时每隔3～5分钟测定一次;点测是从打开铁口8～10分钟即铁水流满第一罐时开始测定,中间再测定3～4次,然后取其平均值,加上热电偶尾端温度所对应的毫伏数,作为实测的铁水温度值。
In line with the blast furnace smelting, from June to October 1985, in the Baotou l ~ # blast furnace using plug-in WRLB-600X fast miniature thermocouple, equipped with a potentiometer direct readings, in the main iron trenches mouth and North Slag Mouth ditch, on the iron slag in the slag out of the temperature measurement and even the measured connection. Even measured from the hot metal flow through the sand mouth once every 3 to 5 minutes measured; point measurement is from 8 to 10 minutes to open the iron mouth full of molten iron when the first tank began to measure the middle of re-measured 3 to 4 times, and then Take the average, plus the thermocouple temperature corresponding to the millivolt temperature, as measured hot metal temperature value.
