Device and method for synergistic quenching and tempering treatment of steel slag and nonferrous metal smelting slag
The invention discloses a device and a method for synergistic quenching and tempering treatment of steel slag and nonferrous metal smelting slag, and belongs to the technical field of iron and steel metallurgy. The problems that in the prior art, metal resources in the nonferrous metal smelting slag are difficult to recover, slag stacking and stacking environment pollution are serious, high-temperature sensible heat of the steel slag is not fully utilized in a prior steel slag treatment method, and iron oxide in the steel slag is low in recovery rate are solved. The device for synergistic quenching and tempering treatment comprises a quenching and tempering furnace and a driving mechanism, wherein the quenching and tempering furnace comprises a quenching and tempering furnace molten pool,the upper part of the quenching and tempering furnace is provided with a steel slag inlet and a nonferrous metal smelting slag inlet, and the quenching and tempering furnace is also provided with a coal oxygen lance; the driving mechanism is arranged at the bottom of the quenching and tempering furnace and used for driving the quenching and tempering furnace to swing and rotate; and the device further comprises a drying pretreatment unit. The device can carry out synergistic quenching and tempering treatment on steel slag and nonferrous metal smelting slag to realize steel slag modification and iron resource recovery; and the quenched and tempered slag can be used as a cement raw material or an artificial sand stone material for buildings after being treated.
本发明公开了一种钢渣与有色金属冶炼渣协同调质处理的装置及方法，属于钢铁冶金技术领域，解决了现有技术中有色金属冶炼渣中金属资源回收难，渣堆放堆存环境污染严重，现有钢渣处理方法钢渣高温显热未充分利用，钢渣中铁氧化物回收低的问题。协同调质处理的装置包括调质炉和驱动机构，调质炉包括调质炉熔池，调质炉的上部设有钢渣进料口和有色金属冶炼渣进料口，调质炉还设置有煤氧枪；驱动机构设置在调质炉的底部，用于带动调质炉进行摆动回转；还包括烘干预处理单元。本发明的装置能够进行钢渣与有色金属冶炼渣协同调质处理，实现钢渣改性和铁资源回收；调质后渣经过处理能做水泥原料或建筑用人造砂石料。
