Q:does the electric kiln burner need to be sealed?
seal when open the kiln, and observe the temperature, when the temperature reaches a point, you can move the firebrick away, and continue observing the temperature to decide whether to seal it or not, but do not seal it completely, repeat the procudure until reach the sinter point or skill requirement.
Q:air-cooled razheng times of magnesia-alumina spinel refractory bricks
The ingredients are magnesium, oxygen, and aluminum. the components of spinel refractory can be magnesia-alumina spinel with excessive aluminium oxide, or magnesia-alumina spinel with excessive magnesium oxide. excessive magnesium oxide and aluminium oxide can form magnesia-alumina spinel in above 1700 degrees.
Q:Whether fireclay raw materials or clinker are used when masonrying general fireclay brick? What is the difference between raw material and clinker?
Of course is clinker, the raw material belongs to precast block, besides, clay and chamotte are mixed with glassy water and fine powder, fine powder belongs to raw materials.
Q:How to deal with the red kiln in rotary kiln?
Q:There are various refractory materials inside many kilns such as refractory brick, what is the role of masonry of these refractory materials?
Heat insulation
Q:How many years are the service life of chimney lining refractory brick?
Capacitance magnesite, seawater magnesite, should be the alkaline refractory brick, magnesia-alumina spinel can absorb hydrogen fluoride, generally are magnesia brick, magnesium iron ore, forsterite, dolomite, magnesium dolomite, magnesium silica sand, magnesia-chorme spinel and magnesia chrome sand: Magnesia mineral, magnesium calcium sand, magnesite, magnesium dolomite sand, dolomite, mainly is cordierite
Q:What is the name of the white clay refractory brick
There are several kinds of white clay, Guangxi clay, Suzhou clay, kaolin
Q:What kind of refractory material is used in the furnace when the boiler reaches more than 1200 degrees?
except refractory brick, refractories include refractory concrete (refractory cement+aggregate), fire-resistant insulating layer (refractory cement+vermiculite powder or refractory cement + diatomaceous earth) and so on.
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:Scheme of cement kiln replacing 40 meter refractory brick kiln
If only replace refractory bricks, it just needs three days under the condition of 200 degrees. It will be simpler if there is only free water in the refractory brick (no pouring material).
