Embodiment 1

[0012] 1) Shovel out the magnesium smelting slag from the reducing tank, cool it naturally to normal temperature, then add 50% water to the magnesium smelting slag, and mix;

[0013] 2) Place the mixed slag at room temperature for one week;

[0014] 3) Send the mixed slag into the brick making machine for molding;

[0015] 4) The formed brick embryo is sent into the carbonization chamber, where it is carbonized by the carbon dioxide flue gas generated after the dolomite is calcined, and becomes a product.

Embodiment 2

[0017] 1) Shovel out the magnesium smelting slag from the reduction tank, cool it down to normal temperature naturally, then add 55% water to the magnesium smelting slag, and mix;

[0018] 2) Place the mixed slag at room temperature for one week, add 40% of the magnesium smelting slag and pulverize it into coal-fired cinders below 10mm, and mix evenly;

[0019] 3) Send the mixed slag into the brick making machine for molding;

[0020] 4) The formed brick embryo is sent into the carbonization chamber, where it is carbonized by the carbon dioxide flue gas generated after the dolomite is calcined, and becomes a product.

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 [0001] The invention relates to a method for preparing bricks from Pidgeon process magnesium smelting slag. Background technique [0002] At present, most of the Pidgeon process magnesium smelting slag and flue gas are naturally discharged and buried, and a small part is sold by adding some cement to make blocks. pollute. Contents of the invention [0003] What the present invention aims to solve is the problem that the existing Pidgeon process metal magnesium smelting slag and flue gas are not utilized, and are directly discharged into the atmosphere, causing environmental pollution. Comprehensive utilization of the preparation method. [0004] Technical solution of the present invention is realized like this. A method for preparing bricks from Pidgeon process magnesium smelting slag, the steps of the preparation method are: [0005] 1) Shovel out the magnesium smelting slag from the reducing tank, cool it naturally to normal temperature, then add 50-6...
