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:Which is better for tunnel kiln suspended ceiling, refractory brick or ceramic fiber module ?
ceramic fiber module is better
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:How to choose refractory brick
The design of size and selection of refractory brick shape mainly depend on the design of industrial furnace lining . The size and shape of refractory bricks must meet the needs of furnace refractory brick masonry, it both ensures the convenience of building and usability of thermal equipment. (such as sealing, insulation, brick grade and service life etc.). When the furnace design company designs furnace lining of refractory bricks, first it should design the size of refractory bricks or choose standard size refractory bricks, sometimes this work is done by a furnace company, sometimes it is done by furnace construction company or furnace maintenance company directly. The refractory bricks that has a certain size designed by the furnace design companies or construction companies, in addition that it should satisfy furnace operation and operation life, it also considers whether it is convenient for refractory factories to produce refractory bricks, besides, it should take into account that whether the pass rate on main production process and finished product rate is high when bricks are moulded, installed and fired. Refractory it is convenient to operate, and is convenient for refractory factory producing, the selection of shape of refractory bricks and the design of and the brick molding, and on this basis, found the relationship between the size of wedge brick, brick level and service life etc.), some even combine refractories with furnace, but each has its inherent regularity. The foreign refractory attaches great importance to building furnace, the height of furnace should be integer times of the thickness of brick (including brickwork joint)
Q:What is the meaning of the new type of dry rotary kiln refractory brick 620,320?
It should be the length of the turn. I'm not sure if it is right.
Q:Can refractory bricks be used when it cracks for 1cm
3, If the crack is caused by burning or drying, then it can't be used. While if the carck is caused by refractory brick molding, it still can be used. 4, the crack is caused by refractory bricks raw materials.
Q:is there any requirement for radioactive materials in refractory materials.
they all do not cause radiological hazards to the environment, so no requirements! analyze rom the element , magnesia. Do not know if it is useful, but material used by refractory materials, firstly any chemical elements are radioactive, human beings can not close, then, such as silicon dioxide: If it is radioactive. analyze from use, such as bauxite, does not have the use value
Q:can the red brick be used as refractory brick?
Can not replace! The high temperature will make it burst. Coefficient of thermal expansion is not enough
Q:Is the diameter of 2.5 meters of the calcium aluminate powder rotary kiln referred to the inner diameter of the refractory brick?
No, it should be outer diameter.
Q:what is consequence of high load and soft low of high alumina refractory brick ?
softening, if not up to the design requirements, may cause vicious incident like the collapse of the stove in use. the full name is softening temperature under a fixed load, as the name suggests, it is the softening temperature after adding the load.
