To increase recovery of high carbon ferrochrome, the effecting factors of chrome contents in slags were analysed, and the preliminary test of adding waste magnesia brick and magnesite were conducted.
为了提高高碳铬铁的回收率，分析了影响渣中铬含量的因素，并通过配加废镁砖和菱镁矿作了初步试验。

The magnesite-chrome refractories used in the critical parts of copper, nickel and lead making furnaces, and refractories used in various parts of aluminium reduction cell are described as well.
并对炼铜、炼镍、炼铅炉关键部位所用镁铬材料，炼料、铝电解槽各部位所用材料进行了阐述与介绍。
