Q:Can iron oxide be used as refractory material?
Iron oxide can not be used as refractory material, but it can be used as refractory additive. Iron oxide can be used as pigment
Q:Where the refractory bricks rider bricks that are used for building arch and vault should be put?
Arch and vault shall be built simultaneously from both sides of the arch of the foot to the center of symmetry, when masonry, inverting concentric reducer of arch brick is prohibited; the lock should be driven into the brick arch from the side, if the last rider brick can't be driven from the side, you can process the first 1-2 brick to make the size of the lock and the lock buckle equal, and then drive suitable rider brick from top, and use steel plate to jam-pack the side; dismantling arch tire must be performed after all rider bricks are driven and lock brick arch foot ditch masonry is completed and the final tightening nut for skeleton retractor rear.
Q:What is the price of the first grade high alumina brick?
Many factories in Xinmi have high alumina bricks, but they must choose a regular factory. Kuwait refractory level high aluminum brick price at around 1600, the quality of double stable supply
Q:Why can earth make bricks?
Brick is a common masonry material. Brick and tile production and use in China has a long history, "Qin Zhuanhan tile". The raw material for brick making is easy to obtain, the production process is simple, the price is low, the volume of urine is in the combination, and the clay brick also has the advantages of fire protection, heat insulation, sound insulation, moisture absorption, etc..
Q:What kind of refractory brick is suitable for clinker production line of 2,500 tons?
are you saying the cement plant rotary kiln?
Q:The brick and ordinary clay brick which is expensive
Of course expensive materials sintered clay brick, sintered clay brick fired common clay, shale and shale and coal gangue as raw materials by high temperature firing,
Q:Are refractory bricks, burner block and thermal insulation brick the same? Are they the same thing?
The burner block is heavy, its using temperature is high, while thermal insulation brick is light and its using temperature is lower than heavy brick.
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 high alumina brick resist carburizing?
It is heavy brick mullite brick, brick to do the heavy weight to more than 2.4 manufacturers can achieve a few feeling
Q:The introduction of mullite brick
High alumina refractory with crystalline mullite (3Al2O3, 2SiO2) as the main crystal phase.
