A new method of processing steel slags. It comprises:a. adding an agent for improving property into a slag tank;2) casting into clinkers, cooling rapidly by water;3) separating by magnetic bodies;4) hydrolyzing in a upright processor;5) separating by magnetic rollers, the first sieving;2) cracking;7) separating by magnetic rollers, the second sieving; 8) pulverizing by a ball mill;9) separating by magnetic rollers, the third sieving;10) finely pulverizing by a vibrating mill. 一种钢渣改质水淬蒸气处理新工艺，包括1、在渣罐中加入改质剂；2、流经中间盘进入链带式浅盘机铸成渣块，急冷打水；3、磁盘磁选；4、立式处理器中水解；5、磁辊磁选，第一次筛分；6、锤破机粉碎；7、二次磁辊磁选，筛分；8、球磨机粉碎；9、第三次磁辊磁选；1 0、超细振动磨机精磨。为实现上述工艺采用与铸铁机相同的链带式浅盘机铸成渣块，采用具有上下双钟进出料管制，螺旋放料的具有通入蒸气环管的罐式立式处理器进行水解，采用本工艺及设备实现了钢渣处理的自动化连续生产，省工省时，处理效率高，成本低，且无环境污染。
