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.
Dimension of brick of mark of brick of tall aluminous light qualitative heat preservation is 230*114*65mm, the weight of a brick and density are concerned, 1 body weigh 1.7 kilograms one piece close, the sheet with 0.8 secret system weighs 1.36 kilograms, a 1KG with 0.6 secret system. Current bid brick is general the brick has versatility, include wide content range, have roughly the following at 2 o'clock 1. Include standard brick, general...
Weight of light qualitative tall aluminous brick is light, heat preservation area is high temperature resistant performance is good, more expensive than brick of light qualitative clay, but use temperature is higher also. Heat preservation sex is better, it is 10 times of concrete of light qualitative heat preservation commonner. Aluminous content of light qualitative tall aluminous brick is in 40-45% above, intensity 6-7Mpa, color is whiter than brick of light qualitative clay, chosen method also is first look down on is qualitative tall...
Tall aluminium gets together brick of light heat preservation belongs to fireproof material, also belong to insulation material, have good high temperature capability, heat preservation heat proof quality is good, manufacturing technology introduces below, interested friend can understand together below. Light qualitative tall aluminous brick is the important heat-insulating material of furnace of hot project kiln, alumina content is more than 48% , basically mix by Molaishi Bo...
Cupola uses firebrick with body of heater of fireproof material cupola, because layer of job of upside of body of heater suffers when makings be pounded to the machinery of charging and wear away, cause is common need not build by laying bricks or stones builds common firebrick, with sector build by laying bricks or stones of hollow iron brick is built, external use shaft of quartz arenaceous fill is lower working layer, be in especially the place of shaft, because suffer the clay of high strenth...
Cotton of fiber of pottery and porcelain is to be in industrial electric stove high temperature is fused and high pure the raw material such as argillaceous grog, alumina pink, silica pink, chromic Ying Sha, form a fluid. Use next compress air is blown or swing into fiber shape with the machine that swing silk, the cotton that use part implement collect cotton, form cotton of fiber of pottery and porcelain. Fiber cotton can machine fiber blanket further, board, paper, cloth...
Determine to pledge density of the porosity of heat preservation brick, bulk and bibulous rate are in light material firebrick gently, the per cent that basically is the stomatic bulk in pointing to a product and product volume calls porosity. Gas hole rate basically has apparent pore to lead (namely percent opening) , closed pore rate and true porosity, product porosity shows apparent pore is led commonly, with " % " ...
Heat preservation is fireproof material is to point to porosity low, heat conduction leads density of tall, bulk low fireproof stuff, weigh light simple fireproof stuff again. Include heat preservation fireproof fiber and fireproof product, fireproof fiber product. The basis uses temperature, microtherm heat preservation is fireproof material, use temperature is under 900 ℃ , if goods of brick of diatomite heat preservation, silica, silicon is calcic...
The characteristic of firebrick and heat preservation brick is different. the function with respect to firebrick and adiabatic brick, we can think firebrick is to be aimed at for certain fireproof, and adiabatic brick pays attention to heat proof quality more. And more specific we still understand from the parameter below. Sex of first selection heat preservation, the coefficient of thermal conductivity of heat preservation brick is in commonly 0.2-0.4(is average...
Almost manufacturer of every tall aluminous firebrick has corresponding pull current Cheng, recipe craft decided the weight of the product, if weigh qualitative brick to need ambitious force to squelch for many times,shape, more compact, intensity is high, wearability is good, the brick that light qualitative tall aluminous brick produces according to recipe craft is lighter, have good heat preservation performance. Tall aluminous firebrick produces work...
Silica brick fights thermal shock sex to differ, those who fight acidity slag erode ability strong, good in the stability when 600 ℃ above is used for a long time, can use 10-15 year, can use 25 years or so even. Silicon pledges the brick is typical acidity firebrick, its SiO2 content not under 93% . Oxide Al2O3 and FeO, Fe2O3 it is better to have be able to bear or endure suffer a gender, but right...
Mo Laishi brick is the aluminous silicon that gives priority to brilliant photograph with Molaishi fireproof product. Mo Laishi brick as a result of its main brilliant photograph is Molaishi, its property basically depends on Molaishi. Fireproof function of Mo Laishi is in 1850 the left and right sides, suffer bear bate temperature tall, high temperature creep is small, shake sex is good, fight acid slag corrode. Mo Laishi brick is to show with not coming stone is given priority to...
Manage of brick of tall aluminous light qualitative heat preservation changes index to the intensity of body close density, compression, heavy change that burn a line, coefficient of thermal conductivity, material pledges content and impurity reach use temperature to wait, kiln furnace liner undertakes selection according to using a requirement, had these index to be able to know whether this product can be used, the manage of fireproof material changes index to detect is by many special apparatus...
