Ronghua Refractory Technology Co., Ltd. focuses on the research and development and manufacturing of refractory materials and has cooperated with many high-temperature companies around the world for many years.
Tall aluminous brick is a kind of fireproof material, its bases is AL2O3. If AL2O3 content prep above 90% , call corundum brick. Because resource is different, the standard of different country agrees not completely also. For example, european country is to the AL2O3 content floor level of expensive aluminous fireproof stuff 42% . Be in our country, AL2O3 content presses tall aluminium commonly fireproof...
Brick of light qualitative clay is fireproof degree tall, low-cost, at present 1 with 0.8 density be in a ton, the price of 0.6 wants a few more expensive. Adiabatic and fireproof material is to point to porosity density of tall, bulk is low, heat conduction leads low fireproof stuff, adiabatic and fireproof data says again for light simple fireproof stuff, it includes adiabatic and refractory products, fireproof staple...
Utility of brick of heat insolation of tall aluminium of light qualitative heat preservation and characteristic: 230*114*65mmLG-0.8 of tall aluminous qualitative adiabatic brick, have bulk density small, coefficient of thermal conductivity the characteristic with stability of low, quality, superior heat proof quality, can use at the liner of kiln of of all kinds furnace or thermal insulation. The product has Zhengzhou glory related Cheng Naicai insulation material: Firebrick of Mo Laishi heat insolation, ...
What carbon pledges raw material to calcine basically is used is rotary kiln and furnace of to calcine of coal tub type, in raw material isolation airy condition issues the high temperature processing that undertakes 1250-1500 is spent, liner has firebrick, fireproof and heat preservation brick, pouring expect etc. Furnace of roast of carbolic simple goods can be divided according to structural type and operation method for furnace of type of intermittent type furnace, experienced add, batch-type furnace, ...
Corundum brick is the firebrick of the corundum brilliant photograph that points to white commonly, bases is alumina, have electric frit and agglomeration according to manufacturing technology, detailed introduction looks please below. Producing corundum brick place to use raw material is will high pure after industrial alumina passes to calcine fine grind (also add a few MgO additive sometimes, in order to improve) of its crystal structure, suppress is become...
Silicon line stone is a kind natural and advanced fireproof and mineral, it has heat to expand rate is low, fight metallurgy slaggy with all sorts of glass fluid erode, high temperature wearability is good wait for a characteristic. Its manage turning performance is better than tall aluminous brick, fireproof 1830 ℃ of degree of 1770 ～ , loading bate begins 1650 ℃ of bit of 1500 ～ . Utility of silicon line stone 1 high temperature resistant prevent wear paint; 2 silicon line...
Zirconium not comes stone brick is the founding that is raw material with Molaishi and zirconia refractory products. Structure of crystal of brick of founding of zirconium Mo Laishi is compact, loading bate temperature is high, thermal stability is good, mechanical intensity is high below normal temperature and high temperature, wearability is good, thermal conductivity is good, and have the capacity that admirable resistance erodes. Agglomeration zirconium not comes stone brick is to employ worker worker...
Compound Molaishi the brick is two layer or multilayer material is qualitative compound produce and become, have the effect such as heat preservation of wear-resisting heat insolation. Firebrick is comprised by working layer, thermal insulation, use synchronism to shape, synchronous combustion technology. Working layer uses electric frit Mo Laishi, leveling aluminous grog, high grade andalusite, additive, alkali resistance erodes ability strong, be able to bear or endure tall...
According to fireproof material different, steel wraps the construction method of liner to also differ, be like the choice of firebrick, construction method is body of build by laying bricks or stones, irrigate the alternative that builds material to build construction to irrigate, have by the bag breathe freely brick, also have without breathe freely brick, still work is changed breathe freely the brick. Include the discussion of liner craft and test through of all kinds to the steelworks steel, liner is departmental...
Tall aluminous brick calls light qualitative heat preservation tall aluminous adiabatic brick again. Among them alumina content is in the 48% above, light qualitative fireproof material that basically constitutes jointly by Molaishi and corundum. Bulk density is about between 0.4 ～ 1.35g/cm3. Apparent pore rate is in about 66% ～ 73% between, compression intensity 1 ～ 8MPa. Have good heatproof shake performance. Light...
The choice of brick of adiabatic and fireproof heat preservation and specific requirement are concerned, if coefficient of thermal conductivity, temperature, density, material is qualitative,content is waited a moment. Density of the material composition of brick of light qualitative adiabatic heat preservation and structure, porosity and stomatic feature, bulk, temperature is main factor. Brick of fireproof and adiabatic heat preservation main effect is heat preservation heat insolation, reduce heat energy prediction of a person's luck in a given year, ...
Does fireproof material have torpedo pot what characteristic? Regard metallurgy as the important segment of the industry, fireproof material must have pot of torpedo of molten iron pretreatment sex of shake of good acid-proof sex broken bits and basic slag aggressivity, heat-resisting and be able to bear or endure flake quality. Generally speaking, not the torpedo canister of desulphurization is used firing argillaceous brick or andalusite brick, liner uses argillaceous brick commonly...
