Specifications

Magnetic Chrome Brick
ISO9001:2000 Certificate

Burnt magnesia-chrome bricks are made from high quality mag-nesia and chrome concentrate, cr2o3 content can be adjusted according to different requirements. The bricks have good thermal stability and high temperature performance, and are widely used in cement kilns and non-ferrous rnetal metallur-gical furnaces and so on. High temperature burnt directly bonded magnesia-chrome bricks, semi-rebonded magne-sia-chrome bricks and rebonded magnesia-chrome bricks are made from low impurity raw materials. All or part of raw ma-terials are preburnt or electro fused. The best proportioning, high pressure moulding, ultra high temperature and good vol-ume stability. The bricks are widely used in large cement ro-tary kiln, and secondary refining units such as RH, VOD, AOD furnaces, non-ferrous metal met-allurgical furnaces, glass tanks and so on.

Q:What are the differences between thermal insulation bricks and refractory bricks?
Thermal insulation brick is thermal insulative; refractory brick is high temperature resistant.
Q:What kind of coal should be used to burn refractory brick? and how many calories smoke is suitable?
It can't be the surface of coal, at least it is coal seed.
Q:application of phosphate refractory bricks
The 4 properties of phosphate refractory bricks: (1) high strength wear resistance (2) and chemical erosion (its alkali resistant ability is better than that of clay brick and high alumina brick) (3) and good thermal shock resistance (4) high load softening temperature in rotary kiln, kilneye, kiln Zone door cover, cooling machine and lining refractory brick falling parts easy to loose
Q:Is the thickness of the kiln lining and the refractory brick the same concept?
This is certainly not the same. The thickness of the refractory brick can be arbitrary, the thickness of the kiln lining is generally designed according to requirement
Q:Do refractory bricks need to be sent to the lab to test after arriving the site?
Other is nothing, generally it does not need, whether single weight meets the requirements, whether the appearance is regular, usually only to see whether the size is standard, it is set in the procurement
Q:What is the biggest difference between refractory bricks and clay refractory bricks?
Q:How to wipe off the white paint on the refractory brick (red).
Cover the wall gap with tape. . Then paint the bricks. Finally, tear the tape off. .
Q:do the used refractory bricks pollute the environment?
the main pollution of refractory brick is coal gas pollution in the process of burning , it can be recycled to produce aggregate, waste brick has no pollution.
Q:How to make refractory bricks? ? ?
Solution of the production of refractory brick raw materials
Q:Is the waste of the fire resistant hazardous waste?
it mainly depends on whether the refractory bricks contain chromium, if not, we only need to properly dispose of them, it would cost less and assure that there is no bad effect on people and the environment, shoot two hawks with one arrow; if there is hazardous elements like chromium and mercury, it may cost much and be disposed as industrial waste(or construction waste) by local environmental protection department, it is ok if there is a large amount of waste, because the environmental protection department will not take those waste that is not obviously dangerous seriously, even if it is dangerous waste. If there is no suitable manufacturers. It is better to look for a refractory brick manufacturers to recycle it, the cost is acceptable if the amount is small. In general, these heavy metal containing refractory bricks need to be disposed by the company that has quality to dispose such hazardous waste.
