Q:Do refractory bricks resist corrosion and sulfur?
There are anticorrosion and acid proof refractory bricks
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: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:How to deal with the red kiln in rotary kiln?
Q:What are the hazards of solid clay bricks?
The production of clay brick destroys 500 thousand mu per year
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:can Methanol burn refractory brick?
The upper part of the radiation chamber of the methanol oven is made of ceramic fiber, and the lower part is generally used refractory brick.
Q:The difference between fireclay brick and refractory cilica brick in the application.
Good thermal shock stability, long-term use temperature is not higher than 1300 degrees, high temperature, high strength, low price of clay brick characteristics, thermal shock stability is the worst, a scrap, can be long-term used under the condition of high temperature (exceed 1400 degrees Celsius) . The temperature of silica brick's soft bearing is close to the melting point. Other industries basically don't use, but the comprehensive performance of high temperature is not good, widely used in low temperature parts of a variety of furnaces. The silica brick is generally used in the coke oven and glass kiln, but anti alkali erosion ability is poor
Q:Do cement kiln refractory bricks have quality guarantee period? can them still be used for a long time's pile?
They of course can be used. The plant will produce some bricks for standby application in advance, so they put for a period of time is completely no problem
Q:The advantages of using alkalinty refractory brick?
Magnesia chrome and other spinel refractories alkalinity refractories; (2) the alkalescent chrome magnesite refractories, alkaline solvent resistance is strong, usually refers to the magnesia refractory material, dolomite brick and calcareous refractory materials, dolomite refractory materials and lime refractory materials, acid flux or acid refractory chemical reaction. Mainly used in alkaline steel furnace and non-ferrous smelting furnace. Alkaline refractory material at high temperature for alkaline slag. Mainly as the following categories, but the acid slag, forsterite refractories and magnalium: (1)strongly alkaline magnesia brick, magnesia carbon brick and cement kiln
