Refractory brick is dense shaped refractory material. With high refractoriness and mechanical behavior under high temperature, refractory brick is the necessary material of high-temperature services, mainly used for industrial furnaces and kilns and thermal equipment.

Refractory brick has wide applications, mainly used in metallurgy, construction(cement and glass), petroleum, chemical industry, electric power and machine building.

Q: What are the application of used refractory brick pieces?: auxiliary material made of refractory bricks or refractory is not as good as that of bauxite.

Q: What materials make of clay insulating fireclay brick?: Clay insulation bricks are general according to the different origins of raw materials, not the same

Q: Should kiln be warmed before the ignition of the new furnace?: If you don't have to heat up the furnace. The new furnace must be heated up, and the temperature should be increased according to the heating-up furnace curve, so the current situation you meet is appeared

Q: How to choose refractory brick: First of all, design the refractory brick size or select the standard size of refractory bricks directly, resist high temperature, and convenient. There are many types of refractory bricks produced by refractory material factory, has heat insulation, so needless to say the country, this work is done by a furnace company . The qualified rate of loading and firing brick and other major production on the process and the final product rate is high, and the brick molding. Too much types of the refractory brick is not easy: is a refractory material factory to accept and use the same brick production models will be more to the degree of refractory brick amazing wide. Whether the furnace design companies or construction companies design certain size refractory bricks, in addition to satisfying the furnace operation and service life.Hiphotos, wear resistance. management and calculation have brought great difficulties, it must also be taken into account that whether refractory bricks produced by the refractory material factory is convenient, low temperature But for intermodulation between refractory bricks factory, redundancy of refractory factories prepare lots of brick mould, this is convenient for operation and construction. A large number of furnace design anticorrosion company design brasque, sometimes work is done by furnace construction company or furnace repair company. if each company that has its own furnace and thermal equipment designs refractory bricks suitable for themselved, it should take into account the general systematic and standard

Q: Expansion ratio of light corundum fireproofing brick: And then the appropriate drying, the using temperature 1500~1700 degrees of light corundum brick, the porosity is 70% to 80% Now, use foaming method to produce light corundum brick, 3g&#47, shaped idiosome with mould dry for 4 days in 60 degree to 70 degree oast, it will demoulding, foaming method and evaporating method produce light corundum brick, the thermal conductivity is 0. the containing of AL203 has difference, the corundum brick that use corundum hollow?sphere to produce contain the highest AL203 Finished light corundum brick don't have accurate shape and size after firing.8 1, so products need mechanical or manual cutting after the kiln, finally, firing in 1300 degree and 1550 degree, basically still meters with water forming, just add to burn: 50~60h, because its production methods and the introduction of additives are different, the total sintering time.17W&#47, light corundum fireproofing brick can be made into density is 0, withstand voltage strength is 4MPa, the containing of A1203 is no more than 99%.

Q: What is the problem about splintering when the refractory brick is fired?: There are many bubbles inside the refractory brick, it is also possible that the brick itself is not up to the standard about volume density, then refractory brick fragmentates. There are many reasons, may be in the process of repression

Q: How much fireclay is needed per cube refractory bricks?: Normal refractory bricks need to use 70-80kg refractory mud each cubic . In fact, this can be calculated, because the volume of refractory bricks and refractory mud density can be measured. Of course, here is an important point, that is the size of the brick seam, 1mm brick seam and 3mm is significantly different. Sichuan brand refractory mud has many kinds, like high aluminum, clay, corundum, magnesia, insulation and so on, the dosage is different.

Q: can Methanol burn refractory brick?: Generally speaking, all the fuel can burn, mainly to see the calorific value and consumption ratio

Q: How many degrees of refractory brick if its surface turns red, how to test the temperature of refractory brick after it is burnt to red.: But it depends on materials; for example, if clay brick is pink, it calls underburnt temperature is 700 degrees -900 degrees, paste red is called overdo temperature 1350 degrees -1390 degree, if the color turns heavier, it will be deformation. there are many reasons for refractory bricks sintering

Q: Do refractory bricks insulate heat?: The light brick inside the brick is heat insulation brick, according to the different bulk density, the effect is also different
