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.
Nonferrous metal smelt is more complex to the requirement of fireproof material, should have already enough high temperature resistant quality, still need to have particular high temperature strength, need to have at the same time fight broken bits goodly to erode reach the capacity that fights slag, flue gas to erode, because this is having firm demand to the choice of fireproof material inside furnace. At the same time to all sorts of nonferrous metal...
Light qualitative adiabatic firebrick belongs to insulation material, can reduce kiln put oneself in another's position medicinal powder hot sex, save kiln furnace specific power consumption, also can reduce kiln style quality, reduce the integrated cost of kiln. The main use of light simple adiabatic and fireproof stuff is bulk density. Porosity. Coefficient of thermal conductivity. Use temperature and mechanical intensity. Can achieve without how many insulation material...
The fiber that by the SiO melt of the Al2O3 that contains ％ of 43 ％ ~55 and ％ of 42 ％ ~54 siliceous aluminium glass makes calls siliceous aluminous fiber. Use normally blow or cast filar legal system to become staple, do not contain lubricant, content of broken bits ball is low, it is stuff of stuff of high temperature kiln and vacuum shape the good stuff of the product; Cast silk to grow, blame fiber content is low, divide...
Brick of light qualitative corundum, light qualitative corundum not comes Shi Zhuankang flakes the gender is strong. Bulk density is 1.5-1.7g/cm3, basically use as kiln of high temperature channel. Temperature of drawer kiln liner can be as high as 1700 ℃ , density of bulk of brick of liner of kiln of path of roller of brick of heat preservation of kiln of high temperature channel, ejector plate kiln is 1.3-1.4g/cm3. As a result of its production methods and introduced additive...
Silicon Mo Zhuanzhuan is Al2O3-SiO2-SiC fastens fireproof material, commonly used at cement kiln. Produce craft raw material: Use tall aluminous alumina to make raw material, add Bai Gangyu, inferior pink of stone of line of corundum of Bai Gangyu, palm, silicon, andalusite, clay (earth of Guangxi white mud, Suzhou) , pink of Si of pink of stone of silicon small pink, candle, metal and Al pink, unripe tall
Heat preservation brick is one of commonly used insulation material that furnace of high temperature kiln realizes energy-saving environmental protection, insulation material still has pledge gently pouring the product such as makings and heat preservation cotton. Heat preservation brick has a lot of kinds, if pledge argillaceous brick, tall aluminium gets together gently,brick of light brick, heat preservation of light qualitative silica brick, diatomite, Molaishi gets together light brick (JM series) alumina is hollow ball brick, zirconia is hollow...
Accept rice material mixes 650 degrees for 950 degrees according to temperature cent, pledge again 400 kilograms / M3, pledge gently 300 kilograms / M3, 300 degrees, coefficient of thermal conductivity 300 degrees of 0.032w/(m.k) , raw material uses asbestine cloth with soft nap, fly ash. The way of transmission of adiabatic principle caloric of heat-insulating material is accept rice the following 3 kinds of means: Conduct conduct heat, convection passes heat and radiate...
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...
