在工业铝生产中控制适宜的电解温度是一个重要的策略。在电解温度与电解质初晶点之间存在过热度,现代铝电解槽选择适宜的电解温度,并控制过热度在5～10℃之间,以求得良好的生产指标。文中还介绍了一项连续测温技术,使用等离于喷涂尖晶石的钢质保护管,用铬基—镍基合金热电偶进行连续测温。
Controlling the proper electrolysis temperature in industrial aluminum production is an important strategy. The superheat exists between the electrolysis temperature and the primary crystallization point of the electrolyte. The modern electrolysis cell selects the suitable electrolysis temperature and controls the degree of superheat between 5 and 10 ° C, in order to obtain good production indexes. The article also introduced a continuous temperature measurement technology, the use of plasma spinel sprayed on the protection of the tube, with a chrome-based nickel-base alloy thermocouple continuous temperature measurement.
