Q:what should press on the heat preserving cotton above the suspended ceiling refractory brick ?: you can also put Z shaped steel on the purline, put heat preserving cotton on the roof boarding, it is easy to oprate.

Q:What can be applied to the burned refractory brick to resist heat shock?: Acidic refractory material use monox as the main component, among which cilica brick and clay brick are commonly used. Silica brick is silicious product containing monox more than 93%, whose raw materials include silica, waste silica brick scrap and etc. The acid resistance of slag erosion ability is good, and the softening temperature under a fixed load is high. The volume won't shrink after repeated burning, but even a slight expand; but it is vulnerable to the erosion of basic slag, and has low thermal shock resistance. The silica brick is mainly used for coke oven, glass melting furnace, acid hearth furnace and other thermal equipments. Clay brick uses refractory clay as the main raw material, containing 30% to 46% of aluminuum oxide, belong to weakly acidic refractories. It has good heat shock resistance and corrosion stability to acid slag, and it's widely used. Neutral refractory materials use aluminum oxides, chromium hemitrioxides or carbons as the main components. Corundum products containing more than 95% of alumina is a kind of high quality refractory material with wide application.

Q:How to repair the boiler?: What kind of boiler, the external wall or the furnace arch, the smoke wall, the material: High-alumina cement, refractory brick, refractory clay, knife brick

Q:How to test the various components of the refractory brick?: It is difficult to distinguish if it is mixed together, fully smashing and mixing. Then assay. Or testing after smashing and separating.

Q:Can red bricks be burned in tunnel kiln which used to burn refractory brick?: Of course. But the temperature to burn refractory brick is very high, the average temperature is above 1500 degrees. And the temperature to burn brick is not so high, about 1200 degrees. So you should control the temperature, the tunnel kiln to burn firebrick and the tunnel kiln to burn red brick are the same, there is just a little bit difference in the materials used to build the stove!

Q:Clay brick, red brick, always fried brick how to do?: Small white stones, such as Magnesium Oxide and limestone (calcium carbonate). Take "containing limestone" (calcium carbonate) stones, after firing, into lime (calcium oxide), put a long time, absorb the moisture in the air, will cause the lime (calcium oxide) reduction, volume expansion, resulting in fried brick.

Q:What is the density of the high alumina refractory brick?: According to the quality, the general level is two point four to two point seven or so

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: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:Whether yellow dextrin is used in refractory bricks?: The production of refractory bricks needs yellow dextrin as bonded materials.
