The commonly used fireproof material on kiln furnace has which a few kinds

     The commonly used fireproof material on kiln furnace has which a few kinds, the capacity that commonly used fireproof material can use heatproof concussion and chemistry erode commonly, coefficient of thermal conductivity is low with the metalloid material with small coefficient of expansion. Fireproof data limited company serves as furnace of kiln of Zhengzhou Rong Cheng be able to bear or endure the navigate of material domain person, can supply more than 140 kinds of fireproof data, product function can satisfy the service requirement that shows industry of level great majority, product quality is good, price material benefit, stock up is enough, offer money punctual, protect maintain a volume character. Zhengzhou flourish Cheng Naicai produces finalize the design fireproof material basically can be divided it is 3 kinds big, it is acidity and fireproof material respectively, alkalescent and fireproof material, neuter and fireproof material.
Flourish fills acidity and fireproof material to be bases with oxidation silicon, have silica brick and argillaceous brick commonly usedly. Silica brick is to contain oxidation silicon the silicon simple product of 94 ％ above, use raw material has silica, useless silica brick to wait, its fight acidity slag to erode ability strong, loading bate temperature is high, the bulk after repeating to calcine is not contractive, expand somewhat even; But its suffer basic slag easily erode, heatproof shake sex is poor. Silica brick basically is used at furnace of kiln of frit of Jiao Lu, glass, acidity steel-making to wait for hot project facilities. Argillaceous brick is main raw material with saggar, contain 30 ％ ～ the alumina of 46 ％ , belong to weak acidity and fireproof data, heatproof brace up quality Fireproof stuff is good, have the sex that fight corrode to acidity slag, application is wide.
Flourish fills alkalescent and fireproof material to be bases with calcium of magnesian, oxidation, commonly used is magnesia brick. Contain magnesian 85 ％ of 80 ％ ～ the magnesia brick of above, have very good repellency to basic slag and iron broken bits, fireproof degree taller than argillaceous brick and silica brick. Basically use on equipment of smelt of the open-hearth furnace, converter that blow oxygen, electric stove, nonferrous metal and equipment of a few high temperature.
     Flourish fills neuter and fireproof material to be bases with chromium of alumina, oxidation or carbon. Contain alumina the corundum goods of 95 ％ above is the high quality fireproof data with a kind of more extensive use. The chromic brick that is bases with oxidation chromium is right of slag be able to bear or endure corrode sex is good, but heatproof shake sex is poorer, high temperature loading is out of shape temperature is inferior. Carbon pledges fireproof material has simple product of goods of carbolic brick, black lead and carborundum, its heat up coefficient of expansion very low, thermal conductivity is tall, heat-resisting shake performance is good, high temperature intensity is high, fight soda acid and salt erode, lose especially soda acid has better counteractive capacity, do not get metal and slaggy benefit wet, qualitative light. Use as extensively material of high temperature lining, also use as the high-pressured boiler liner of oil, chemical industry.
     Zhengzhou flourish fills fireproof material to hold to " the market is this, the guiding principle of perfect ego " , carry out overall quality management. Scientific administrative mechanism, solid technology supports, detect perfectly method, excellent tooling, sound service system ensures product quality is stable, for goods seasonable, service is subtle.
