Abstract

The invention relates to a production method for making bricks by using a titanium slag wall material, which comprises the following steps: firstly making a cementing material by the following components in percentage by weight: 45 to 65 percent of fine titanium slag, 8 to 12 percent of lime, 3 to 6 percent of semi-hydrated gypsum, 10 to 20 percent of coal ash, and 10 to 20 percent of cement; then mixing the cementing material and aggregate, adding water into the mixture and evenly stirring the mixture; and finally pressing the stirred material by a brick press to mold, putting the molded material into a curing chamber, and steaming the molded material for 12 to 18 hours at a temperature of between 80 and 100 DEG C, wherein each material is blended in percentage by weight: 25 to 40 percent of the cementing material, 50 to 65 percent of the aggregate, and 5 to 15 percent of water, and the aggregate is water quenching granular titanium slag and crushed slow cooling titanium slag. The titanium slag accounts for more than 70 percent of the raw materials, so the production method can utilize the titanium slag on a large scale, reduce farmland occupancy and reduce environmental pollution; and the made brick has the advantages of high intensity, simple production and low cost.

Description

technical field [0001] The invention relates to a processing method of titanium slag, in particular to a production method for making bricks with titanium slag wall materials. Background technique [0002] Slag is a by-product of blast furnace ironmaking. When blast furnace ironmaking is used, in addition to iron ore and coke, a considerable amount of limestone and dolomite must be added as solvents. CaO, MgO and iron ore obtained from the decomposition of limestone and dolomite The waste ore and the ash in the coke are melted together, and the molten slag mainly composed of calcium silicate and calcium aluminosilicate is formed. Its specific gravity is 2.3-2.8, which is lighter than molten iron and therefore floats on the molten iron. After being discharged, it is quenched and quenched into granular slag, commonly known as slag. [0003] Ordinary slag exists in the form of glass and has high activity. It has been widely used as cement mixture or concrete admixture. Now it ...
