General Information of Fireclay brick

Our corporation producesa comprehensive range of Fireclay bricks, with 30% to 55% alumina content, allof these bricks exhibit excellent performance.

Our Fireclaybricks are the final result of blending excellent fused alumina and silicon asthe main raw materials with cutting-edge technology, adding superfine powder,after mixing, drying, forming, in the high temperature shuttle kiln. We ensureyou that the Fireclay Bricks made by us possess high quality standard and havegone through all the complicated quality control parameters. Their durabilityand strength adds life to the structure and they have the capacity of bearinghigh temperature.

Feature of Fireclay Brick

Resistant tothermal shock, abrasion, chemical attack

High ability foranti-abrasion during work

Low shrinkagedegree under high temperature so as to maintaining integrity of the furnacelining

Low apparentporosity, and low Fe₂O₃ content to reduce the carbondeposit in the blowhole and avoid the bricks broken in case of expansion

Applications of Fireclay Brick

Fireclay brick is mainlyused in the part of throat, stack, hearth, bottom for blast furnace and thestack for a big blast furnace.

Q:What is the role of refractory brick, whether is there any books to introduce refractory bricks: Refractory bricks are generally used to build a hearth. Such as, boiler, furnace (molten metal), air heating furnace etc, the furnace need refractory bricks to bulid.

Q:What is the use of refractory bricks: Most are industrial ceramics, glass, metallurgy, refractory brick kiln lining. It is also widely used in high temperature electromagnetism, magnetic materials, electronic ceramics, high alumina, clay, metallurgy, pharmaceutical, lithium industry pusher-type furnace.

Q:What material does tile tunnel kiln use to replace the refractory brick to have better insulation effect and save the maintenance and prolong the service life?: The price is high, but the the service life is not longer than the clay brick, some use high aluminia brick. Currently, there are no refractory products that can replace refractory bricks. The effect is good of choosing fireclay brick with high strength dense, low porosity clay brick. We have maken several lines of refractory bricks. Actually, if you choose good refractory brick, the service life will be very long. The kiln temperature is not high.

Q:What mud is the refractory brick made of?: Firing with refractory clay, the main component is AI2O3

Q:In tunnel kiln, what is the meaning of refractory proportion 2.0?: The proportion of refractory bricks is related to the density.

Q:What is the material of refractory brick used in the high temperature zone of the kiln?: The ordinary generally use clay high alumious fireclay brick. GB/T 3994-2005 insulating refractory brick. What with good material is high-grade thermal insulation refractory brick. GB/T 3995-2006, high alumina thermal insulation refractory brick , model A13, is made of aluminium oxide, A13 50U, senior heat insulatio brick B5

Q:how heavy are boiler of six tons plus refractory bricks?: The total weight is about 60 tons, 6 tons of bulk boiler steel, insulation materials, sealing materials, refractory material

Q:why the color of refractory brick is white after high temperature firing when the meteorite is black after the burning?: There are different reasons. Meteorolites can mainly be divided into three types, iron meteorites (iron nickel alloy): Stone meteorites (the main component is silicate), and stony iron meteorites(the mixture of iron and silicate)

Q:Is refractory brick afraid of rain?: High alumina clay is not afraid of rain, but covering is better, magnesium carbon refractory brick had better not be rained.
