辽南地区电熔镁砂的发展现状

Development status of fused magnesia in southern Liaoning

电熔镁砂主要作为炼钢转炉、精炼钢包渣线以及炼钢电炉炉衬镁碳砖不可取代的原料,已在辽南地区形成了400万t以上的生产能力。但由于电熔镁砂下游市场、生产原料、生产技术和装备等原因,电熔镁砂生产存在供需不平衡、能耗高、产品质量波动大等问题。为此,阐述了近年来辽南地区电熔镁砂的现状与变化,并指出了电熔镁砂未来的发展趋势。

Fused magnesia is a main irreplaceable raw material of magnesia-carbon bricks for the linings of steelmaking converters,steelmaking electric furnaces and refining ladle slag lines,which has a production capacity of 4 million tons in southern Liaoning.However,due to its downstream market,production raw materials,as well as production technology and equipment,problems for the fused magnesia production exist such as the imbalance of supply and demand,high energy consumption and large fluctuation of product quality.Therefore,the status and changes of fused magnesia in southern Liaoning in recent years were expounded.The future development trend of fused magnesia was pointed out.
