（1）工艺流程描述
Process description
钢销、钢渣粒子钢、钢渣精粉、高品位铁粉还原等液压压制成型系统工艺是将钢销、钢渣粒子钢由上料机加入到系统设备，由低温对流烘干器和调温器进行温度控制，对钢渣粒子钢进行烘干，然后经中间转运器输送到液压成型机，经液压按需求调整液压压力（0-315bar动态可调）压制成型后将压制好的粒子钢块由装载机吊运至成品库，期间部分热量由***换热器进行回收利用，设计有除尘系统对生产过程中产生的废气、粉尘等污染进行环保处理。
Steel pin, steel slag particle steel, steel slag powder, high-grade iron powder reduction and other hydraulic pressing forming system technology is to add steel pin and steel slag particle steel to the system equipment by feeder, temperature control by low-temperature convection dryer and precise thermostat, drying steel slag particle steel, and then conveyed to the hydraulic forming machine through intermediate conveyor, hydraulic pressure adjusted according to demand (0. - 315bar dynamic adjustable) After pressing, the pressed steel particles are hoisted from loader to finished product warehouse, during which part of the heat is recovered and utilized by high efficiency heat exchanger, and a dust removal system is designed to deal with environmental pollution such as waste gas and dust produced in the production process.

3、安全可靠、优势明显
Safety, reliability and ***ious advantages
A、渣钢根据粒度不同以不同方式回收利用
Slag steel is recycled in different ways according to its particle size.
（1）A1级渣钢，TFe≥80%，粒度>75（mm）为初选渣钢，经电磁除铁器选出，供给转炉炼钢使用。
Grade A1 slag steel with TFe (> 80%) and particle size > 75 (mm) is the primary slag steel selected by electromagnetic iron remover and supplied to converter steelmaking.
（2）A2级渣钢，TFe≥80%，粒度10-75（mm）2#棒磨机提纯后，进入2#振动筛，筛上产物，供给转炉炼钢使用。
Class A2 slag steel with TFe (> 80%) and particle size of 10-75 (mm) 2 # bar mill is purified, and then it enters 2 # vibrating screen. The products are screened and supplied to converter steelmaking.
