Abstract
The production method of magnesium cement and other related magnesium cement product includes the following steps: using waste slag produced by smelting magnesium at high temp. as raw material, water-quenching and cooling to below 500 deg.C, naturally cooling and drying for 2-3 days, controlling loss on ignition and making it less than 5% so as to reduce harmful components to cement and raise its activity. It can be used as mixing material of cement, can obviously reduce cement cost, and can save energy source.
Description
The invention belongs to the building materials production technology, relate generally to the production technique of magnesium slag as cement mixture.
Lead for utilizing the magnesium slag to appear in the newspapers, opened up new approach, cause extensive concern for the utilization and the manufacture of cement of magnesium slag as cement mixture.But comparatively sophisticated production technique waits to determine that the quality of product is also understable.
The objective of the invention is to propose to utilize magnesium-smelting waste residues to produce the process program of cement.
The object of the present invention is achieved like this, utilizing magnesium-smelting waste residues to produce technology compound and masonry cement comprises: raw material is prepared burden and enter the raw mill grinding by the calcination of chamotte requirement, balling-up then, through calcine grog, grog and other blended materials all after fragmentation, are gone into pure storage warehouse respectively with the magnesium slag as blended material again, prepare burden by the cement products requirement, behind the cement grinding mill grinding, go into cement and store and homogenizing storehouse, get product.Wherein used magnesium-smelting waste residues is above after Water Quenching at 900 degree Celsius in the batching, is cooled to below 500 degree Celsius, and dry 2-3 days of naturally cooling is controlled loss on ignition and is lower than 5%, and it is stand-by to enter pure storage warehouse then.Like this, the shrend meeting produces magnesium-smelting waste residues to help improving its active variation and clears up in the slag the deleterious free composition of soundness of cement, makes the cement products stable performance, and the object of the invention is achieved.
The prescription of cement of the present invention (quality %):
When product is complex cement: gypsum 3 ± 0.5 zeolites 6 ± 1 magnesium slags 37 ± 3 Portland clinkers 54 ± 3;
When product is masonry cement: gypsum 3 ± 0.5 zeolites 8 ± 1 magnesium slags 45 ± 3 Portland clinkers 44 ± 3;
The prescription of calcination of cement clinker of the present invention (quality %): gypsum 1.3 ± 0.2 magnesium slags 20 ± 1 Wingdales 54 ± 2 clays 12 ± 1 iron ores 3 ± 0.2 hard coals 8 ± 1 fluorites 1 ± 0.1.More than be to utilize magnesium-smelting waste residues to produce several relevant proportion scheme of cement
After the present invention carries out Water Quenching to the magnesium-smelting waste residues that becomes source of pollution, the development of restriction refining magnesium industry, objectionable constituent, obviously raising activity have been reduced to cement, be used as cement mixture, successfully realize utilizing the magnesium slag to produce relevant cement products with big mixed ratio, and can significantly reduce manufacture of cement cost, save energy.Provide a kind of simultaneously and utilize magnesium-smelting waste residues, reduce and pollute, protect environment, releasing to refine magnesium industry trouble and worry, make magnesium already go on the effective way on the road of fast development.
The invention will be further described below in conjunction with embodiment.
The waste residue that the used refining magnesium of first embodiment factory discharges, its MgO content is between 6-10%, when coming out of the stove, waste residue makes it in 3-5 minute, to reduce to rapidly below 500 degree Celsius with the water spray, through 2-3 days naturally cooling dryings, loss on ignition is 5% when following, and it is stand-by as cement mixture to take in pure storage warehouse.This routine product is 425
#Prescription during complex cement (quality %) is: gypsum 3.5 zeolites 7 magnesium slags 36.5 525
#Portland clinker 53.Its cement fineness was a 0.08mm screenings 6.8%, was the 47.4Mpa folding strength through checking its 28 days ultimate compression strength. be 7.1Mpa.
Second embodiment is consistent with last example, and just product is the prescription (quality %) of masonry cement: gypsum 3.5 zeolites 9 magnesium slags 44 525# Portland clinkers 43.5.Its cement fineness was a 0.08mm screenings 8.7%, was the 39.4Mpa folding strength through checking its 28 days ultimate compression strength. be 6.5Mpa.
The 3rd embodiment is still consistent with last example, and the prescription (quality %) that product changes calcination of cement clinker into is: gypsum 1.3 magnesium slags 21.1 Wingdales 54.7 clays 11.3 iron ores 3.2 hard coals 7.3 fluorites 1.1.Is 7.8Mpa through checking its 28 days ultimate compression strength for the 61.4Mpa folding strength.
