1 前言1983年6月戴维麦基(Davy Mckee)已完成一家煤基直接还原厂的建设,该厂为斯凯瓦电弧炉炼钢提供成本低、质量高的原料。投产两年来(已生产150多kt),该厂始终把注意力集中在产品质量上,因为只要产品的金属化出现不一致,在炼钢过程中使用这种产品就会产生一系列的问题。 1 INTRODUCTION Davy McKee completed construction of a coal-based direct reduction plant in June 1983. The plant supplies low cost, high quality raw materials for Skye EAF steelmaking. Two years into operation (more than 150 kt have been produced), the plant has always focused on product quality, as long as there is inconsistency in the metallization of the product, the use of such product in the steelmaking process creates a series of problems.
