尖晶石矿物对工业铝电解质和铝液具有良好的抗腐蚀性,尖晶石涂层的热电偶保护管可以应用于工业铝电解槽的连续测温。本文研究了尖晶石矿物对工业铝电解质和铝液的抗腐蚀性及尖晶石涂层电偶保护管在工业铝电解生产中的应用,并连续测量了一个阳极工作周期的铝电解温度曲线。
Spinel minerals have good corrosion resistance to industrial aluminum electrolytes and molten aluminum. Spinel-coated thermocouple tubes can be used for continuous temperature measurement in industrial aluminum cells. In this paper, the corrosion resistance of spinel minerals to industrial aluminum electrolyte and molten aluminum and the application of spinel-coated galvanic protection tube in industrial aluminum electrolysis were studied. The aluminum electrolysis temperature curve of one anode working cycle was continuously measured .
