2In the system in the compositing range of cinder microcrystalline glass, make product through operation such as fusion, homogenizing, moulding, micritization and annealing.With slakin devitrified glass of the present invention, its hear rate has only about 40% of cold dosing method slakin devitrified glass, has only 20%～30% of normal silicate glass production hear rate.
Description
The present invention relates to the manufacturing technology of cinder microcrystalline glass.
Cinder microcrystalline glass is the silicate mine slag microcrystalline glass that utilizes industrial slags or slag to make.With ordinary silicon salt glassy phase ratio, the physical strength height of this devitrified glass, corrosion resistance and good, resistance to chemical corrosion are strong, both Industrial products be can make,, architectural constructional materials and health porcelain also can be made as the inwall of water pump cover, chemical reaction pot or lining material etc.Its raw material is an industrial residue, and wide material sources, amount is big, cost is low, is easy to form large-tonnage production, thereby is subject to people's attention.Abroad, the Soviet Union, Britain does a lot of work, especially Soviet Union, dropped into industrial production as far back as the seventies, raw material is the metallurgy high temperature slag, again be equipped with quartz sand and auxiliary material, found with tank furnace and to form (Soviet Union's " cinder microcrystalline glass product description " and " external cinder microcrystalline glass data compilation ", information institute of building scientific research institute 1973.12 of country), Shang Glass Articles Works No.2 utilizes flyash to produce black glass ceramic (CN85100521) at home, devitrified glass (CN89105864.8) is directly made with titanium-containing blast furnace slag by Chongqing silicate institute, recently Huadong Chemical College and Lianyun Harbour glass two factories utilize phosphorus ore tailing, test manufacture cinder microcrystalline glass (CN89102816).The slakin devitrified glass all is cold batchings, founds both at home and abroad at present, and these class methods have been utilized some industrial residue, have improved environment, cost is lower, but the same with simple glass production, energy consumption is higher, about 1.1 tons in its process fuel product consumption per ton mark coal.
In phosphorus production, 1 ton of yellow phosphorus of every product will be discharged 10 tons of 1500 ℃ of pyritous molten slags, can only make the adulterant of cement of low index fully after the shrend.Grain slag value per ton only is about 10 yuan.Present domestic annual more than 300 ten thousand tons of slags of discharging, wherein major part is not utilized.Shrend water causes the stacking of environmental pollution, slag will take a large amount of soils.Equally, some power plant of China adopts coal-fired power cyclone boiler, and its fusion of discharging 1350～1420 ℃ increases the calcium slag, is used as mostly to pave or the cement of low index raw material after shrend, granulation.Also have, Iron And Steel Industry both domestic and external will be discharged more than one hundred million tons slag every year, and the slag temperature reaches 1600 ℃, more than the heat of a few class industry furnace slags all be not utilized.
The objective of the invention is to overcome the high shortcoming of present domestic external cooling dosing method slakin devitrified glass energy consumption, provide and directly utilize the industry furnace slag, the method for heat batching slakin devitrified glass.
The worker who realizes the object of the invention is a molten slag, and before discharging cooling, not shrend, heat batching add a certain amount of raw material and nucleus agent that contains silicon oxide, aluminum oxide, calcium oxide, magnesium oxide and sodium oxide, make melt composition drop on CaO-Al
