Abstract
A process for preparing Mg-slag brick includes collecting Mg slag from reducing reactor, natural cooling, mixing with water, still standing for 7 days, shaping, and carbnifying the brick blank by CO2 fume generated by calcining dolomite during smelting Mg. It can decrease environment pollution of smelting Mg.
Description
Technical field
The present invention relates to a kind of method for making brick with slag form smelting magnesium by Pidgeon process.
Background technology
At present, Pidgeon process magnesium metal smelting slag and flue gas, major part all adopts the nature discharging and buries, and small part adopts admixture portion water mud to make building block and sells, and the dolomite calcination flue gas is not utilized, and directly discharges atmosphere, causes environmental pollution.
Summary of the invention
To be solved by this invention is exactly that existing Pidgeon process magnesium metal smelting slag and flue gas are not utilized, and directly discharges atmosphere, causes environmental pollution problems, and a kind of preparation method who together fully utilizes that magnesium metal smelting slag and flue gas are added who provides.
Technical solution of the present invention is to realize like this.A kind of method for making brick with slag form smelting magnesium by Pidgeon process, this preparation method's step is:
1) smelting magnesium slag is shoveled out from the reduction jar, naturally cool to normal temperature, add 50～60% water then to smelting magnesium slag, mix;
2) mixed slag charge is placed a week at normal temperatures;
3) this is mixed slag and send into moulding in the brick press;
4) the brick embryo after the moulding is sent in the carbonization chamber, and the carbonic acid gas flue gas that produces after by dolomite calcination in the carbonization chamber carries out carbonization, promptly becomes product.
Also can add 30～50% coal-fired cinder in the described smelting magnesium slag, make this product.
With preparation method's brickmaking of the present invention, technology is very simple, can make full use of the slag and the flue gas that produce in the existing Pidgeon process magnesium metal smelting process, because waste residue and waste gas comprehensive utilization are made material of construction, reduced the shared arable land of deslagging and to the pollution of environment, simultaneously reduced carbonic acid gas again, reduced the influence of carbonic acid gas the Greenhouse effect of atmosphere generation to atmospheric discharging quantity.
