转炉炼钢炉渣(简称“钢渣”)约为粗钢产量的10%~15%,其数量很大,若得不到妥善处理则易造成长期占用土地、污染环境和浪费资源。与高炉渣不同的是钢渣目前的应用范围较窄,且应用价值偏低,除一小部分磷高的渣用作肥料外,主要用于筑路的垫料。其原因是转炉钢渣碱度大,含氧化钙高,
Converter steel-making slag (referred to as “steel slag”) is about 10% ~ 15% of the crude steel output, which is large in quantity. If it is not properly handled, it may easily cause long-term occupation of land, environmental pollution and waste of resources. Different from blast furnace slag, slag is currently used in a narrow range of applications with low application value. Except for a small part of phosphorus with high slag used as fertilizer, the slag is mainly used for road construction. The reason is that converter slag basicity, containing calcium oxide high,
