  • Aerification furnace pledges firebrick build by laying bricks or stones builds what the method reachs compressive strength to rise gently

    Circular fluid-bed / construction of aerification furnace liner pledges gently of firebrick compressive strength raise a method because light qualitative firebrick makes the matter such as craft, the product that production comes out often compares tall aluminous brick in intensity or argillaceous brick is a lot of poorer, general need increases its compressive strength through a few craft. Improve light qualitative firebrick the method of mechanical function, ...

  • Change furnace technical properties and regulation of fireproof material construction

    Change furnace one of crucial equipment that technical properties changes furnace is synthetic ammonia plant. As production large change, a paragraph structure more hasten is complex, heat pipe increases hundreds Ken, operation requirement requirement is strict, is average temperature in tube wall 900? 950 ℃ , operation pressure is as high as 3.9MPa(40kgf/Cm2. ) aborning controls good technology character, ...

  • Firebrick of hot-blast stove lining and function introduce

    The action of hot-blast stove lining is heat insolation is mixed bear high temperature load, the capable person that reason defines firebrick of each place lining pledges and when ply, should mix according to temperature of susceptive of place of body of build by laying bricks or stones, bear adiabatic requirement, and flue gas is decided to the condition such as the physics of body of build by laying bricks or stones, chemistry. Upside 30% ? The firebrick that the high temperature area on 40% height uses, should provide...

  • Product of low iron of tall aluminous qualitative adiabatic brick introduces

    Tall aluminous qualitative adiabatic brick is the Al2O3 content that controls for main raw material with aluminous alumina do not be less than the adiabatic and refractory products of 48% . Its produce craft to use bubble method, also can use burn oneself out to add content way. Chinese standard (GB3995, 1983) presses tall aluminous adiabatic brick bulk density cent be LG-1.0, LG-O.9, LG-O.8, LG-0.7, LG-0. ...

  • Property of tall aluminous firebrick reachs the generation element of meshy crackle

    The property tall aluminium of tall aluminous qualitative firebrick pledges one of main job property of firebrick are the structural intensity below high temperature, this one character is out of shape with loading bate temperature comes normally assess. Also determine in recent years sex of creep of its high temperature will reflect strength of structure of its high temperature. Test result makes clear, loading bate temperature follows Al2O3. The addition of content and...

  • Roller path kiln pledges the choice of firebrick reachs compressive strength gently rise

    Roller path kiln should consider the following when choosing light qualitative firebrick: 1. Working temperature, use temperature for a long time namely. The high use temperature of it and adiabatic firebrick is concerned. In foreign standard, high use temperature (classify temperature namely) it is to point to maintain 24h continuously its burn a line to change to not be more than the experimental temperature of 29 again, but this temperature cannot serve as...

  • Steel-making reachs steel-making broken bits with fireproof material to firebrick deliquescent

    Steel-making uses fireproof data (1) converter uses fireproof data at present bedding face of mouth of the furnace cap of converter, tapping, around, bath and hearth all use magnesian carbon brick; Trunnion and position of broken bits line use brick of high strenth magnesian carbon. Magnesian content is 70 ~ commonly in magnesian carbon brick 75 % , black lead content is 16 ~ 20 % , bulk density is 2.8 ~ 2.9g/cm3, ...

  • Structure of heating furnace tubal form and liner use fireproof data

    Heating furnace belongs to one of hot project facilities, liner is formed by fireproof material, cent is boarding and indeterminate form, detailed introduction looks please below. A. Boarding is fireproof fireproof material weighs material figuration namely qualitative firebrick, light qualitative firebrick and heat preservation brick, pledge firebrick is given priority to with fireproof sex again, the combustion method that is used at burner, temperature is higher...

  • According to what firebrick and heat preservation brick choose?

    Want the design requirement according to kiln furnace, for example firebrick of wear-resisting of excel in of wear-resisting place need, without wear-resisting the requirement needs the place of heat preservation heat insolation, use heat preservation brick, kiln furnace liner has layer of heat preservation thermal insulation, wear-resisting to wait mutiple level undertake assorted. The discriminative firebrick of high temperature firebrick and brick of light qualitative heat preservation is the build by laying bricks or stones with high temperature commonly used industry...

  • Light simple fireproof stuff reachs the craft that make hole to introduce

    In the electric stove body of heater that light simple fireproof stuff builds in build by laying bricks or stones, constant cent is fireproof layer, high temperature fireproof heat-insulation layer, medium lukewarm fireproof heat-insulation layer. To reduce boiler setting the accumulation of heat of itself is mixed through boiler setting the quantity of heat of outward be lost, when warming up in order to shorten, ask, managing heat energy, often standing by high temperature of electric stove liner ability of a thermal resistance is put near fireproof layer...

  • Firebrick bulk density and buy the introduction

    How much is the bulk density of firebrick? The bulk density of firebrick is a when firebrick of choose and buy main index, how much is the bulk density of general firebrick, the bulk density that we understand firebrick today this problem, to reference of a few foundations is made when you purchase firebrick. The bulk density of firebrick is to express firebrick...

  • Application of tall aluminous qualitative adiabatic brick and standard are normative

    Tall aluminous qualitative adiabatic brick is the Al2O3 content that controls for main raw material with aluminous alumina do not be less than the adiabatic and refractory products of 48% . Its produce craft to use bubble method, also can use burn oneself out to add content way. <divstyle= "color:#222222;font-family:AR. . .
