Product features: hot blast stove with low creep in yangquan bauxite clinker quality clay brick as the main raw material, after high pressure forming, high temperature sintering. Products high refractoriness under load, medium temperature creep resistance performance is good, is the hot blast stove in the area with the main raw material at low temperature.



Q:What's the difference between a high aluminum brick and a clay brick, two?
Lightweight high alumina bricks are usually made of high alumina bauxite clinker with a small amount of clay. After grinding, the bricks are poured and shaped in the form of slurry by gas or foam method. They are fired at 1300~1500 DEG C. Sometimes industrial alumina can be used instead of some bauxite clinker. Used for lining and insulation of masonry kilns, as well as for areas where there is no strong, high temperature molten material erosion and erosion. When contacting the flame directly, the surface contact temperature shall not be higher than 1350 degrees centigrade.
Q:is it correct that the higher the refractoriness is, the better refractory bricks are?
Not completely correct. Refractory bricks need to be strong in addition to the fire resistance.
Q:The application of wasted refractory bricks
break it and refine copper, its grade is higher than the ore
Q:How to distinguish between sintered clay brick and sintered coal gangue brick
Coal gangue is an industrial waste produced during coal mining. Using coal gangue as raw material for the production of new wall materials, both to protect the ecological environment, but also save the land, save energy, it meets the development policy of wall materials industry in China, is a new wall material attaches great importance to and vigorously support the development of the.
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:Why should the clay bricks be watered first when they are building masonry walls?
Therefore, in order to facilitate the operation, so that the mortar has a suitable hardening and strength growth environment, to ensure the quality of masonry, bricks must be watered before use wet.
Q:The difference between clay bricks and clay bricks?
Sintering bricks do not have clay bricks, so sintering bricks are made of stone. Clay brick is clay cooking, two yo, qualitative difference, but the appearance and color almost, but the quality is very different, life expectancy is also a great gap.
Q:How much refractory material is required for 1 million tons of coke oven
This depends on the number of specific cubic, different factory designs different boiler, we need volume to caculate.
Q:What kind of refractory brick is suitable for 24*28m rotary kiln of 5,000 tons?
Magnesium spinel
