Abstract
The invention relates to a baking-free brick using steel slag as a main raw material. The steel slag baking-free brick of the known technology is high in preparation cost and high in energy consumption in the production process. The baking-free brick is mainly prepared from the following raw materials in percentage by weight: 3 to 15 percent of sodium silicate, 45 to 60 percent of steel slag, 18 to 30 percent of blast furnace granulating slag, and 15 to 25 percent of superfine slag powder. The baking-free brick is prepared by adding various raw materials into a brick maker according to the sequence of steel slag, blast furnace granulating slag, superfine slag powder and sodium silicate, adding water into the brick maker in a mass ratio of the raw materials to the water of 1:(0.1-0.3), pressing and curing for 7-10 days under the natural condition. The prepared steel slag brick has the advantages of low cost, good stability, high compressive strength, small production site and high production efficiency; by using a large quantity of industrial solid wastes, comprehensive utilization and environmental protection of resources are realized, and the treatment problem of the steel slag is effectively solved.
Description
Technical field
What the present invention relates to is that a kind of building energy conservation is non-burning brick, and particularly a kind of non-burning brick take slag as main raw material, belong to building material technical field.
Background technology
Slag is a kind of slag that discharges in steelmaking process, it is the melting slag that contains the oxide compounds such as calcium oxide, magnesium oxide, ferric oxide, silicon oxide, aluminum oxide, manganese oxide of finally discharging in order to adjust molten steel composition in steelmaking process, smelt the slag that steel per ton approximately produces 15%-20%, present stage, China approximately had the slag more than 200,000,000 tons pending.To the treatment process of slag, have multiple at present, such as the remelting of ironmaking slag making raw materials recovery, make steel slag cement, slag micro powder, steel slag wall building blocks etc., but the slag that above method is processed only accounts for the last 20% of slag discharge capacity, also has a large amount of slags without use to need to process.
Preparing steel slag brick is an effective means of slag processing, and the building materials investigator has proposed a lot of just preparation methods of slag brick in recent years, has solved certain Technologies of Steel Slag Treatment problem.China Patent No. is that 200810014015.8 patent discloses a kind of steel scoria unburned brick, this invention take Steel-slag Sand, steel-making slag powder, blast furnace slag, lime as raw material through the compression moulding of brick machine, then through maintenance, pass into CO at a certain temperature
2The process of ageing, the deficiency that this invention exists is high to equipment requirements, be in autoclave the ageing certain hour, therefore cause equipment cost high, complex process, the place that production process needs is large, manpower and materials are many, and the steel slag brick cost of final preparation is high, are difficult for promoting.China Patent No. is the preparation that the patent of CN 102976709 A has been announced a kind of steel slag brick, this patent of invention is take slag, cement, flyash, shale as main raw material, after the brick machine is prepared into base, while being dried to a certain degree, enter in kiln and under 900-1200 ℃ and fired 96 hours, obtain goods, this invention weak point is that preparation cost is high, and the production process energy-output ratio is large.Therefore, preparing a kind of unburned steel quarrel brick with low cost, is the useless quarrel that takes full advantage of after steel-making, the effective way that turns waste into wealth.
Summary of the invention
Purpose of the present invention just is to provide the steel slag brick that a kind of with low cost, product performance are stable, ultimate compression strength is high, production technique is simple, production site is little, utilize in a large number simultaneously Industrial Solid Waste, realize the commercial run environmental protection, overcome simultaneously the existing production cost of brick prepared by present same type of material high, the production process complexity, the deficiency that production process energy consumption and site area are large.
The foregoing invention purpose is achieved through the following technical solutions: a kind of non-burning brick take slag as main raw material, and mainly the raw material by following mass percent (wt%) is prepared from:
Water glass 3-15%, slag 45-60%, blast furnace granulated slag 18-30%, slag micropowder 15-25%;
By following method, prepared by above-mentioned raw materials:
(1) proportionally take various raw materials;
(2) order of various raw materials according to slag-blast furnace granulated slag-slag micropowder-water glass being joined in the brick machine, is the ratio of 1 ︰ 0.1-0.3 with the mass ratio of raw material and water, water is added to preparation together in the brick machine, through compression moulding;
(3) maintenance 7-10 days under field conditions (factors).
Described water glass is the service water glass through modification, and modulus is 1.5-2.5, and solid content is 30% commercial goods;
Described slag is a kind of or two kinds of mixtures that form with arbitrary proportion in converter slag, electric furnace slag, and its stability is qualified slag;
Described blast furnace granulated slag is the water-quenched blast-furnace slag that produces in the blast furnace ironmaking process, and its fineness is 5-100 purpose particulate state slag;
Described slag micropowder is that fineness is at the blast furnace granulated slag of 100-600 purpose through fine grinding.
Take the present invention of above-mentioned measure, the non-burning brick not only cost of preparation is low, good stability, production technique are simple, and can also consume in a large number slag, realizes the comprehensive utilization of resource, and the environmental improvement of steel mill is played to significant role.
