General Information of Low Porosity Fireclay Brick SG12

Our corporation produces a comprehensive range of Low Porosity Fireclay bricks, with 30% to 55% alumina content, all of these bricks exhibit excellent performance.

Our Low Porosity Fireclay bricks are the final result of blending excellent calcined flint clay and calcined bauxite, with cutting-edge technology, adding superfine powder, after mixing, drying, forming, in the high temperature shuttle kiln. We ensure you that the Fireclay Bricks made by us possess high quality standard and have gone through all the complicated quality control parameters. Their durability and strength adds life to the structure and they have the capacity of bearing high temperature.

Low Porosity Fireclay Brick SG12

Feature of Low Porosity Fireclay Brick SG12

Resistant to thermal shock, abrasion, chemical attack

High ability for anti-abrasion during work

Low shrinkage degree under high temperature so as to maintaining integrity of the furnace lining

Low apparent porosity, and low Fe₂O₃ content to reduce the carbon deposit in the blowhole and avoid the bricks broken in case of expansion

Applications of Low Porosity Fireclay Brick SG12

Low Porosity Fireclay Brick SG12 is mainly used in glass furnace.

Q:Should kiln be warmed before the ignition of the new furnace?: New kiln should be slowly heated up, the time should be 20 days to more than 1 month!

Q:What refractory mortar is better if masonrying 4 meters height and 114 mm width of refractory brick: The selection of refractory mud should keep the principle of homogeneous phase with refractory bricks, that is to maintain the same material, according to the suitable temperature, choose appropriate binding agent compensation measuring forging Yao tic surprised boxing super man (phosphate, sodium silicate, or other organic combination), composite high performance admixture, it can be combined better in high temperature.

Q:What kind of material is good to be laid on the kiln car, refractory brick?: Use blankets to suspend ceiling, and modules for wall

Q:What mud is the refractory brick made of?: The main material of the ordinary refractory brick is clay, the main component is aluminium oxide.

Q:What is the proportion of lightweight fireclay bricks?: The ingredients are mixed with water to form plastic mud or mud, by extrusion molding or casting molding, after drying at 1250-1350 Deg. C oxidation atmosphere sintering. The volume density of commonly used clay bricks is between 0.75-1.2g/cm3. In reality, the proportion is 1.

Q:Tunnel kiln firing refractory brick by 0 against the good rely on: Modern advanced kiln has high temperature strength and good thermal shock resistance, better environmental protection, is the most economical and efficient kiln. (3), good resistance to gas erosion, due to tunnel kiln's flue gas discharge temperature is generally not higher than 250℃. In order to guarantee the normal temperature system and pressure system of the kiln. Its firing temperature is at 1200-1900℃: (1) or even higher, the requirement for the firebrick, compared with the intermittent kiln, is an important thermal equipment in refractory industry. It is a kind of energy-saving kiln. Tunnel kiln is a kind of kiln that can continuously produce and has high degree of automation.

Q:Can thick steel plate be used instead of the furnace inside the refractory brick?: It depends on the temperature. The steel plate is a kind of heat conduction material which hasn't heat insulation, which should be based on the working environment.

Q:Refractory brick, high alumina brick, magnesia chrome brick, magnesia brick, clay brick, which type of brick has the highest refractory temperature?: It depends. if high alumina brick is used in kiln, its temperature is above 1700 degree, clay brick is between 1500 degree to 1750 degree, magnesia bricks and magnesia-chrome bricks are about 1500 degree to 1650 degree.

Q:What to do if refractory bricks saltpeter when they are used outdoor: Efflorescence is usually dialysised from brickwork joints, dealing with the gap is ok These white substaince inside the pan tile: Cement efflorescence efflorescence is wow cake section from light leather intestinal common disease inumiya Hua building surface, according to their different causes and manifestations, there is pan cream, white, whitening, cream, on the walls and decorative surface erosion and other names, is the change of soluble saline alkali soil, adobe, brick, cement, mortar, concrete, masonry, ceramic tile, paint and other building materials with temperature, humidity and other external environment, in a water absorption, water transfer, water evaporation process with physical and chemical changes of the original building material damage disease phenomenon, erosion degree also has the very big difference there is a common, get damp, foaming, powder, drum, hollowing, cracking, spalling, mildew and crystallization phenomenon. Cement efflorescence may have some relationship with the quality of the cement, sand, water, air, temperature, humidity, it is a common fault in building. Use cement to do the pebble shape, it also prones to the above problems: A layer of white stuff on the surface. Terms of settlement： Scrape the dust in brickwork joint, pointing again. Use special pointing agents, more resistant to corrosion, not easy to efflorescence.

Q:Why can't gravity retaining walls be made of clay bricks?: Gravity retaining walls are usually made of mortar stone, but no clay bricks are used.No, I don't know. It's possible to use clay bricks instead of clay bricks
