The invention provides a process for treating steel mill iron slag through a tunnel kiln. The process comprises the following steps: S1, laying an inert material at the bottom of the tunnel kiln; S2, uniformly mixing the steel mill iron slag with a cosolvent to prepare green bricks; S3, drying the green bricks in a dryer; S4, loading the green bricks into a kiln car, pushing the kiln car into the tunnel kiln, introducing reducing gas, and firing; and S5, taking the green bricks out of the kiln, and crushing the green bricks into small particles. The process effectively solves the problems of serious hardening, incomplete volatilization of zinc, lead and the like, low valuable metal recovery rate, incapability of recycling generated iron slag and the like in the traditional process.
本发明提出了一种隧道窑处理钢厂铁渣工艺，包括以下步骤：S1.向隧道窑底部铺设惰性物料；S2.将钢厂铁渣与助溶剂混合均匀，制作成砖坯；S3.将砖坯至于干燥器中干燥；S4.将砖坯装至窑车中，推入隧道窑中，通入还原气体，烧制；S5.出窑后，将砖坯破碎成小颗粒。本发明有效解决了传统工艺中严重板结和锌、铅等挥发不彻底，有价金属回收率偏低，且产生的铁渣无法再利用等问题。
