摘　　要：气淬粒化钢渣工艺是一种全新的干法处理钢渣工艺,此工艺既可以干法处理钢渣又可以对液态钢渣的显热进行高效回收。同时,通过对气淬粒化工艺过程进行有效控制可为钢渣制备高附加值产品奠定基础。采用不同孔型的拉瓦尔喷嘴喷吹不同粒径石英砂,冷态模拟液态钢渣气淬粒化过程中渣粒的飞行轨迹,通过正交实验方法研究不同条件下渣粒落地距离和落地宽度,为气淬粒化液态钢渣粒化室和喷嘴结构设计提供理论参考依据。The granulated slag gas quenching process is a new technology for dry processing of steel slag.This process can not only process steel slag without water but also recover efficient heat of liquid slag.At the same time,through the process of gas quenching granulation effective control of slag can lay the foundation for preparation of high value-added products.This paper use different type of nozzle blowing different particle size quartzite,in cold conditions simulated liquid gas quenching graining process of slag trajectories,orthogonal experimental method is studied under the condition of different ground distance and landing width,it provide theoretical references for gas quenching graining liquid steel slag graining and nozzle structure design.
