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.
Blaze of contact of kiln furnace liner has the place that wear-resisting asks to choose heavy qualitative firebrick, the layer of heat preservation heat insulation that does not contact blaze uses light qualitative firebrick. Heavy qualitative firebrick is commonly used at fireproof wear-resisting place, choose heavy qualitative data to give priority to the firebrick that agglomeration comes out. Its itself heft wants to weigh on a lot of times than light qualitative firebrick, in. . .
The heat of the object bilges cold shrinking is natural phenomenon, light qualitative silica brick is to be used at furnace of kiln of heating furnace roof, hot-blast stove, glass to wait for roof of industrial kiln furnace or kiln furnace, silicon pledges coefficient of expansion is adiabatic brick ≤ 1.3% . What is coefficient of expansion? What coefficient of expansion points to is heat expands, it is the circumstance with the constant intensity of pressure outside pointing to falls normally, most material is in temperature...
Bleach bead brick to use float bead the thermal insulation that produces for main raw material is fireproof goods. 20 centuries at the beginning of 70 time, china begins to use float bead firebrick of heat insolation of manufacturing clay sex. Since 80 time, because manufacturing technology is simple, resourceful, product quality is better, use poriferous grog method more or burn dry add bleach bead law production to bleach bead brick. Pink of heat and power plant...
Custom-built alumina is hollow ball special shaped brick is abnormity for the most part, the price is a few more expensive than wanting groovily, particular value wants to be spent easily hard according to what dimension, index reachs production will decide, roughly the price is in 10 thousand one ton or so, detailed price invites report to seek advice. Hollow ball brick uses alumina hollow ball is alumina main raw material, high-powered small pink...
The stand or fall of kiln furnace heat preservation and heat proof quality also affects the service life of the actor bad of product quality and kiln furnace directly. Kiln furnace heat-insulation layer uses brick of Mo Laishi heat preservation is the adiabatic and fireproof product that makes for main raw material with Molaishi. Have high temperature resistant, strength tall, thermal conductance is low, can contact blaze directly, the liner that applies to all sorts of industrial furnace kiln...
Henan tall aluminium gets together light brick is light qualitative figuration fireproof material, common system is closely: 0.6, 0.8, 1, 1.2g/cm3, AL2O3% ≥ 50, 52, 56, these are the main factors that decide product value, a ton roughly the price is in more than 2000 to more than 3000, detailed price invites report to seek advice. Tall aluminium gets together light brick, say tall aluminium gets together again light ball brick...
Heat preservation brick is OK heat preservation is adiabatic, managing the sources of energy, the light qualitative brick that gives priority to with alumina has: Brick of corundum of light qualitative Mo Laishi and light qualitative tall aluminous brick, effect of heat preservation of these two products which good? Understand below first, say which product is good again next. Light qualitative tall aluminous brick also calls tall aluminous heat preservation the brick. Alumina quantity is more than 48% , main by not...
Build by laying bricks or stones builds chimney general interior is argillaceous brick, mid use diatomite brick or diatomite concrete, also can use brick of light qualitative clay, basically see the type of chimney and demand, choose right product to achieve economy, heat preservation, energy-saving result. The brick of diatomite heat insolation with diatomite common brick is raw ore is cut by the appearance of firebrick, be in 80...
Siliceous aluminous insulation material is commonly used the heat preservation that waits for high temperature place at conduit of furnace of high temperature kiln, high temperature is adiabatic, its product has a variety of norms and measure, still have use demand, these are a few elements that constitute the price, detailed price invites report to seek advice. What calls silicon acid of siliceous aluminous fiber aluminous fireproof fiber call pottery and porcelain fiber again, main by 2 oxygen...
The fireproof product that can use for a long time in 1000 degrees high temperature environment has a lot of, can the material of heat preservation heat insolation has siliceous aluminous heat preservation to pledge cotton, blanket, felt, gently pouring brick of makings, heat preservation, with what good? Detailed introduction looks please below. Silicon acid of siliceous aluminous fireproof heat-insulating material is aluminous fireproof heat-insulating material is it is with siliceous aluminous fireproof fiber former...
Brick of frit of Mo Laishi report its are main brilliant photograph is Molaishi, have fireproof sex strong, bate temperature is high, rate of high temperature creep is low, heatproof shake performance is good, acid-proof sex is strong wait for a characteristic, the aluminium that belong to silicon fastens refractory products. The alumina content of Mo Laishi brick is commonly between 65%-75% . Alumina content is low mineral outside dividing Molaishi, still contain a few...
Light qualitative tall aluminous brick is heat preservation brick, rate of its heat conduction is lower, its coefficient of thermal conductivity and system are secret about, system is secret: 03. - 1.2g/cm3, 25 ℃ of ± of W/m.k(350 of coefficient of thermal conductivity) : 0.25-0.45. Specific heat capacity: The material of unit quality, temperature is elevatory (or reduce) 1 ℃ place is absorbed (or give off) quantity of heat. Specific heat capacity is to point to certain amount...
