Abstract
A kind of high-strength cement chamotte is cooperated by Wingdale, clay, hard coal, and adds a small amount of rare-earth mineral and make the proper composition raw material, burn to Calucium Silicate powder that partial melting is able to be principal product.The neutral klining system high-strength cement clinker of affiliated building material industry Cement industry technical field.
The invention solves at present with fluorite, gypsum, iron powder, clay, Wingdale, hard coal six component raw material preparation raw material, complex process, the cost height, quality fluctuation is big, problems such as operation, control, management difficulty, under equal conditions, shaft kiln producer uses the present invention, can obtain distinct economic and social benefit than prior art.
Description
A kind of high-strength cement chamotte is cooperated by Wingdale, clay, hard coal, adds a small amount of rare-earth mineral and makes KH:0.94～0.96; N:1.9～2.1; The raw material of p:1.3～1.5, through the shaft kiln low-firing is principal product with the Calucium Silicate powder.Be mainly used in shaft kiln cement plant production " five big kinds " cement.The technical field of the neutral klining system high-strength cement clinker of affiliated building material industry Cement industry.
Existing shaft kiln is fired the high-strength cement clinker technology, be that last announce of basis≤Chinese building material 〉=NO1986.1 obtained the raw material that national science and technology progress two, third prize-" shaft kiln adopts composite mineralizer low-firing Portland clinker " and " shaft kiln is fired the high-strength cement clinker technology " are provided, proportion scheme and method for cooking, Wingdale, clay, iron powder in routine, mix an amount of fluorite, gypsum or other mine tailing, equipment, raw material investment in the hard coal greatly, the product cost height, the quality instability, shortcomings such as production operation, control, management difficulty.
At present, relevant rare earth has been widely used in fields such as metallurgy, military project, the science and techniques of defence, but the exploitation in Cement industry, research are used and also belonged to blank.
High-strength cement chamotte of the present invention is at above shortcoming, in the selection of raw material, has carried out great improvement on prescription design for scheme and the technological measure.It is characterized in that: cooperate by Wingdale, clay, hard coal, and bring elements such as Fe, Si, Ca, Ai, Ce, Cf, Nb, Nd, Eu, Pa, Pr, La into, make KH:0.94～0.96 by adding a spot of rare-earth mineral; N:1.9～2.1; The raw material of P:1.3-1.5, burn to Calucium Silicate powder that partial melting is able to be principal product.C wherein
3S 〉=53%, C
3S, C
2S content is 68-75%; C
3The S crystal habit is complete, and arris is clear smooth, is the tabular and column stone of six sides of black, C
2S is garden shape, and the garden is fan-shaped.What burn out is principal product with the Calucium Silicate powder, and its physical and chemical performance is good, and F.CaO≤3.0% intensity reaches 625#.
The present invention compares in prior art, not only reduces kind, the quantity of manufacturer's outsourcing raw material, simplifies production technique, saves facility investment, reduces product cost, improves product, the quality of shaft kiln.And since in raw material to multielement, high-octane rare-earth mineral is introduced, the unit heat consumption of lowest total of the melting point, liquid phase viscosity and the grog of molten state has been strengthened the calcining of cement clinker when having reduced the goods and materials calcining.The mineral microstructure is good so employing the present invention can burn out in 1300 ℃-1375 ℃-1300 ℃ scope, and A, B ore deposit are grown normal, and F.CaO is low, and liter is heavy high, and change such as time of coagulation rerum natura can be normal, and intensity reaches the high-strength cement chamotte of 625#.
The present invention is applied to shaft kiln cement plant and produces GB175-85, GB1344-85 five big kind cement.Adopt the present invention not only can reduce total volume of railway freight, obtain better social benefit, just produce the shaft kiln factory of 4.4 ten thousand tons of general cement per year, can year increase 80,000 yuan of profits.
