Abstract

一种钢渣处理工艺，属于转炉炼钢钢渣处理技术领域。转炉渣从闷渣池经打水冷却、分解工艺处理，粒度＜250mm的钢渣使用鄂式破碎机将钢渣破碎至＜70mm，使用跨带式磁选机分离出渣钢，再使用液压圆锥破碎机将钢渣破碎至＜10mm，使用跨带式磁选机分离出渣钢；最终将钢渣处理成＜10mm，渣钢含量＜2％的尾渣。优点在于，设备布局采用立体垂直布置与环型布置相结合的方式，布局紧凑，占地面积小，投资少，钢渣处理效率高。

Description

一种钢渣处理工艺
技术领域
本发明属于转炉炼钢钢渣处理技术领域，特别涉及一种钢渣处理工艺。尤其涉及一种紧凑型钢渣处理工艺。
背景技术
随着钢铁工业快速发展，炼钢新技术不断投入应用，以及社会发展对环保的要求日益提高，钢渣处理逐渐受到钢铁厂家的重视，一般新建钢厂在设计之初就充分考虑钢渣处理场地布置、设备选型等因素，钢渣处理系统布局趋于合理，运行高效顺畅，能够满足钢厂日常生产运转，钢渣再利用的要求；但是，对于部分建厂历史久远的老厂，钢渣处理一般采用冷弃法、热沷法等简单的钢渣处理方法，缺乏后期加工、筛选、回收和再利用的先进手段，对生产运行、环境保护造成不同程度的影响。
发明内容
本发明的目的在于提供一种钢渣处理工艺，解决了钢渣处理用地面积较大的问题。适用于场地面积有限或对原有简单钢渣处理系统进行工艺升级；
一种钢渣处理工艺，具体步骤及参数如下：
1、转炉渣从闷渣池经打水冷却、分解工艺处理完后，倒入250mm×250mm孔径的振动格筛2上，粒度＜250mm的钢渣进入地下原料仓3，由原料仓3下的电磁振动给料机持续给料，电子皮带秤计量后，经由带式输送机5，通过地下通廊运至钢渣二次处理区域6。
2、钢渣进入二次处理区域6后，跨带式磁选机磁选出＜250mm的渣钢，磁选后的钢渣送往70×70mm振动格筛2，筛上＞70mm的钢渣经溜槽进入鄂式破碎机破碎成＜70mm的钢渣。
3、跨带式磁选机磁选出＜70mm的渣钢，磁选后的钢渣送往10×10mm振动格筛2，粒径＞10mm的钢渣经料仓‐电磁振动给料机进入液压圆锥破碎机，破碎成＜10mm的钢渣，跨带式磁选机磁选出＜10mm的渣钢，＜10mm的钢渣经由带式输送机运送至成品间。
最终将钢渣处理成粒径＜10mm，渣钢含量＜2wt％的尾渣。
本发明的优点在于，设备布置采用立体垂直布置与环型布置相结合的方式，具有布局紧凑，占地面积小，投资少，钢渣处理效率高的特点。
附图说明
图1为本发明设备布置示意图。其中，钢渣热闷区域1、振动格筛2、原料仓3、厂区道路4、带式输送机5、钢渣二次处理区域6。
图2为本发明工艺流程示意图。
具体实施方式
转炉渣从闷渣池经打水冷却、分解工艺处理完后，倒入250mm×250mm孔径的格筛上，粒度＜250mm的钢渣进入地下原料仓，由原料仓下的电磁振动给料机持续给料，电子皮带秤计量后，经由带式输送机，通过地下通廊运至钢渣二次处理区域。
钢渣进入二次处理区域后，跨带式磁选机磁选出＜250mm的渣钢，磁选后的钢渣送往70×70mm振动格筛，筛上＞70mm的钢渣经溜槽进入鄂式破碎机破碎成＜70mm的钢渣。
跨带式磁选机磁选出＜70mm的渣钢，磁选后的钢渣送往10×10mm振动格筛，＞10mm的钢渣经料仓‐电磁振动给料机进入液压圆锥破碎机，破碎成＜10mm的钢渣，跨带式磁选机磁选出＜10mm的渣钢，＜10mm的钢渣经由带式输送机运送至成品间。
