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.
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...
Cheng Naicai of flourish of anchorage solid brick has, and offer custom-built production, the price is reasonable, provide instructor and construction service, because line of the products is more, cheng Naicai needs flourish to have quoted price according to particular case. Condole hangs condole of brick, anchorage solid brick to hang a brick to call anchorage solid the brick again. Roof structure is hanged by metallic condole raise with the stress between firebrick...
Industrial kiln furnace belongs to high temperature equipment, separate facility is not to resist high temperature, erode and tatty, need refractory products to provide protection, select material undeserved or what construction issue can affect furnace of high temperature kiln is normal move. The chamber of a stove or furnace uses armor plate to coil to make and be become, as temperature elevatory, intensity of the chamber of a stove or furnace is reduced. Undertake to the product roast when, ...
Phosphate combines tall aluminous brick, it is the blame that a kind of heat treatment makes bakes bricks, it is good to have wearability, commonly used at mouth of condenser, kiln, turn kiln transfers belt and cooling zone. Phosphatic brick is dry base manage and technology measure. Do not burn tall aluminous brick (phosphate of the following abbreviation brick) basically use at cement industry. In recent years, as the work up of the market, ...

Liner of large blast furnace needs fireproof material to be as high as thousands of tons, include fireproof and firebrick, fireproof mud, pouring makings, etc, the choice of liner material, basically see use position. The chamber of a stove or furnace is the passageway of molten iron of slag eduction high temperature and slag, produce the effect that a variety of elements suffer in the process. Of the molten iron in thermal current and slag acuteness erode with...
