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.
The thermal shock stability of silica brick is not tall, be poorer in fireproof material, but temperature of its loading bate and fireproof degree more adjacent, silica brick has good repellency to acidity slag, commonly used at vitreous kiln, Jiao Lu, hot-blast stove, used good word can be used 10 to 20 years of above. The quality mark of silica brick SiO2 not under 93 ％ ...
Heat insolation is irrigated build expecting is the indeterminate form that is used at heat preservation thermal insulation fireproof material, product value quotes according to material character with density, kiln furnace heat preservation needs to have logical choice according to temperature design, if heat preservation brick, heat preservation is pouring,cotton of makings, heat preservation is waited a moment. Pledge gently fireproof and pouring expecting is a kind of water hard pouring makings, apply to all sorts of kiln furnace inside...
Hollow ball brick and corundum not come to alumina stone brick belongs to alumina products of data of qualitative fireproof I, bases is 3 oxygen 2 melt aluminium, both manufacturing technology and brilliant resemble certain distinction, the price is different also, system of hollow ball brick takes 1.4-1.8g/cm3 closely, the system of Mo Laishi brick is in corundum closely 2-3g/cm3. Alumina is hollow ball brick is with...
Get together a kind brick of light ball tall aluminium is heat preservation brick, weight jumps over effect of light heat preservation to had been jumped over, there are a lot of blebs equably inside bricky body, compression intensity is not so high, in 2-5.98Mpa. Light qualitative firebrick is used at kiln furnace, warm up drop in temperature faster, efficiency of kiln furnace cycle is taller. The use temperature of light qualitative adiabatic firebrick is ℃ of 900 ℃ ~1650, ...
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...
