Abstract
The present invention discloses a glass kiln silicon firebrick production method, and belongs to the field of production of refractories; a glass kiln silicon firebrick is prepared from the following raw materials by weight: 65-70% of melted quartz powder, 25-30% of periclase powder, 2% of a nanoglue solution and 3% of polyacrylamide aqueous solution by magnetic separation, mixing, forming, sintering and other processes, and a product is mainly used for vaults and other load-bearing parts of thermal kilns of all kinds of glass, ceramics, carbon calcining furnaces and firebricks, also can be used in high temperature bearing parts of hot-blast stoves, but is not suitable for being used in thermal equipment with large temperature fluctuations at the temperature below 600 DEG C.
Description
Technical field:
The invention belongs to refractory materials production field, particularly relate to the production method of a kind of glass furnace silicon refractory brick.
Background technology:
Glass is mainly made raw material with quartz sand and soda ash and is made through high temperature melting, glass furnace is exactly the equipment of fusion cast glass, glass furnace kind is more, such as tank furnace, crucible kiln etc., the most general a kind of kiln type applied in glass industry by tank furnace, it is built into by refractory brick, the damage of glass furnace kiln lining is mainly based on chemical erosion, and have the effect of thermal stresses, the degree of chemical erosion, speed and use position, kiln temperature, molten glass kind is closely related, certainly the quality of lining body itself is also most important, select glass melter refractory brick, kiln type should be considered, use position and Wear mechanism thereof, the kind of melting glass and the kind etc. of fuel, the pool wall that cell furnace contacts with glass metal and Di Deng position, pond, at present generally with containing zirconium laying fireproof bricks, in order to reduce costs, can with different laying fireproof bricks at other position of glass furnace. silica brick, refer to containing the refractory brick of SiO2 content more than 93%, it it is the main kind of acid refractory brick, it is mainly used in vault and other weight bearing areas of the thermal kiln furnace for various glass, pottery, carbon calciner, refractory brick, in the high temperature weight bearing area also use of hotblast stove, but should not use below 600 DEG C and in the big Thermal Equipment of temperature fluctuation. the main component of silicon refractory brick is SiO2, produces by raw material of fused quartz powder and periclasite powder, this kind of brick refractoriness height during production, and hot strength is big, and alkali-resistivity scouring is strong, and good heat stability, also has certain adaptability to acid slag. the present invention is the production method of a kind of silicon refractory brick, the method produces silicon refractory brick taking magnetic separator, blending machine, silica brick set of molds, shuttle kiln as equipment, the method have use general-purpose equipment, simple to operate, production efficiency height, good product quality, environmental protection, be applicable to suitability for industrialized production etc. series of advantages. summary of the invention:
The problem that the present invention mainly solves there is provided the production method of a kind of glass furnace silicon refractory brick, the method is taking magnetic separator, blending machine, silica brick set of molds, shuttle kiln as equipment, it may also be useful to raw material be by weight ratio: fused quartz powder 65-70%, periclasite powder 25-30%, nanometer glue solution 2%, polyacrylamide solution 3% are for raw material is to produce glass furnace silicon refractory brick.
The technical solution used in the present invention is:
(1) fused quartz powder of formula ratio, periclasite powder are sent into magnetic separator, by in the process of magnetic separator, powerful magnetic force by above-mentioned two kinds of pulvis containing iron powder sucking-off, obtain pure fused quartz powder, periclasite powder, then blending machine is sent into, nanometer glue solution of formula ratio, polyacrylamide solution are added, even blend simultaneously.
(2) blend composition in blending machine is sent into silica brick mould, by the mode of pressurization, vibrations, blend composition is combined closely, be processed into and adapt to the refractory brick that some position of glass furnace requires shape, naturally dry 39-41 hour.
(3) mould is sloughed, silicon refractory brick after drying is sent into shuttle kiln, first after the sintering temperature in shuttle kiln is risen to 350 DEG C from 0 DEG C by the time of 2-3 hour slowly, in 1 hours, sintering temperature is risen to 1150-1200 DEG C from 350 DEG C fast again, maintain this and after temperature 22-24 hour, stop heating, silica brick blank is progressively cooled to finished product after normal temperature.
The further technical scheme of the present invention is:
Magnetic separator described in step (1) is CTB6012 type.
Shuttle kiln described in step (3) is coal gas generation shuttle kiln, and when sintering temperature is 1175 DEG C, sintering time is 23 hours.
The invention has the beneficial effects as follows: the production method providing a kind of glass furnace silicon refractory brick, the method uses general-purpose equipment and rational in infrastructure, production technique is simple, production efficiency height, good product quality, environmental protection, and it is suitable for suitability for industrialized production, product is mainly used in vault and other weight bearing areas of the thermal kiln furnace of various glass, pottery, carbon calciner, refractory brick, in the high temperature weight bearing area also use of hotblast stove, but should not use below 600 DEG C and in the big Thermal Equipment of temperature fluctuation.
