本文研究氮化硅结合碳化硅耐火砖的抗腐蚀性和抗氧化性的测试方法,一种新的测试方法是在电解质中通入二氧化碳气体来模拟实际电解过程中电解槽内部的工作状态,这种新的测试方法测定了试样在电解质和二氧化碳共侵蚀作用下的性能,有利于了解电解槽内衬材料在铝工业电解中的腐蚀状况.且根据该方法制定了一个性能测试标准.同时测试了试样在高温下耐电解质、铝液的腐蚀性和在空气中的抗氧化性.这些测试方法简单易操作,且对于试样的性能有较好的评价.

研究了采用高岭土型煤矸石为原料,经碳热还原制取的铝硅铁合金为还原剂热还原炼镁的工艺条件。发现,与传统的硅铁还原剂相比,此还原剂具有还原温度低、还原速度快、过量系数小、制团压力低等优点。经初步估算采用此种还原剂,在相同的还原率下,把每日二个生产周期改成每日三个生产周期是完全可能的。若如此,在镁的产量可增加产品产量约1/3的同时,镁的成本约降低1680元/吨镁左右。
