- 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 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.
- Q: Does circulating fluidized bed boiler's furnace wall use refractory to have thermal insulation?
- Heat insulation cotton is laid behind refractory brick.
- Q: What are the simple ways to distinguish between excessive clay bricks and less fired clay bricks?
- Generally speaking, compared with the exterior burning brick, the internal combustion brick not only saves the clay and the waste material, but also has smaller volume density, lower thermal conductivity, and can increase the intensity by about 20%. Burnover light color, sound, low intensity; burned brick deep color, crisp sound, high strength, irregular size. These two kinds of bricks are unqualified products.
- Q: What kind of refractory brick is suitable for clinker production line of 2,500 tons?
- High alumina brick;
- Q: Would you please tell me how to use the simple method to identify shale brick, clay brick?
- Is the shale as raw material for high temperature baked bricks using shale and coal gangue, clay brick not dense surface, general clay brick for load-bearing structure, relatively thick, single shape; shale brick shapes, shapes with holes, in non bearing structure.
- Q: the refractory brick in glass furnace burner was burning, the bricks on both sides of the fire hole were burning the blocked it, what will cause brick burning?
- The firebrick in glass melting furnace is mainly consisted of zircon brick, other ordinary refractory materials can not effectively prevent the erosion of glass solution. Because the glass melting liquid is eutectic mixture compared to the refractory bricks, it penetrates into the refractory brick and reduces its original performance, simply speaking, the glass melting liquid dissolves the refractory bricks as eutectic mixture .
- Q: The harm of wet bricks used in refractory bricks
- Increase the natural protection time, increase the baking time, or water can not discharge, this will cause swelling deformation of furnace wall.
- 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.
