炼钢炉熔池温度如用pt-pt-Rd插入式热电偶测量,则指示较为准确。问题在于保护套管的制造。钢铁研究院对插入式热电偶保护管曾进行过一系列的试制工作,现简要报导如下:原料:所用原料为矾土,电熔氧化铝,刚玉,碳化矽,矽铁和粘土等。工序:工序为原较→磨细→除铁→过筛→配料→混和→调桨→困料→浇注→干燥→烧成成分和测验:
Steelmaking furnace bath temperature as measured using pt-pt-Rd plug-in thermocouple, the instructions are more accurate. The problem is in the manufacture of protective sleeves. Iron and Steel Institute of thermocouple inserted thermocouples have conducted a series of trial work, are briefly reported as follows: Raw materials: raw materials used for the alumina, fused alumina, corundum, silicon carbide, silicon and iron and clay. Process: The process is the original more than grinding → iron removal → sift → ingredients → mixing → → paddle → dumped material → pouring → drying → baking ingredients and test:
