Features of impregnation a corrosive medium for the working layer of the lining of rotary kilns and casting ladles for ferroalloy production are considered, and results are provided for analysis of the impregnation thickness. The change in the thermal conductivity of refractories after service is investigated on the basis of a developed and patented method. It is found that the thermal conductivity of the refractory material of an industrial furnace lining working layer increases (by 5 – 12%) due to refractory impregnation by a corrosive medium.

耐火导热系数对腐蚀性介质浸渍的依赖性研究

考虑了用于铁合金生产的回转窑和浇铸钢包衬里工作层的腐蚀介质浸渍特性，并提供了用于分析浸渍厚度的结果。维修后的耐火材料导热系数的变化是根据已开发并获得专利的方法进行研究的。结果发现，由于腐蚀性介质的耐火材料浸渍，工业炉衬工作层的耐火材料的热导率增加了（5％– 12％）。
