Q: What are the application of used refractory brick pieces?
auxiliary material made of refractory bricks or refractory is not as good as that of bauxite.
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: Shale brick and clay brick? Answer before you know it
Has the advantages of high strength, thermal insulation, heat insulation, sound insulation and other characteristics, in order to shale as the main building materials brick construction, is the biggest advantage of shale brick and clay brick traditional construction method is exactly the same, without any additional special ` construction facilities, special tools, is the best substitute for traditional clay solid brick.
Q: What refractory mortar is better if masonrying 4 meters height and 114 mm width of refractory brick
Use high aluminum refractory cement!
Q: Is refractory brick afraid of rain?
High alumina clay is not afraid of rain, but covering is better, magnesium carbon refractory brick had better not be rained.
Q: What bricks are used for constructting refractory bricks tunnel kiln what is the material of each burning zone brick
To reduce the cost from a professional point of view, you should have the construction team to set up the specific solution for you, be sure to keep in mind not to save blindly, the best is to use refractory brick
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: Do cement kiln refractory bricks have quality guarantee period? can them still be used for a long time's pile?
They of course can be used. The plant will produce some bricks for standby application in advance, so they put for a period of time is completely no problem
Q: Are buildings allowed to use red bricks?
Is the red brick with clay, shale, coal gangue as raw materials, crushing, mixing kneading with artificial or mechanical pressing, sintering and building bricks after drying at 900 centigrade temperature by oxidizing flame firing. Also called clay brick. Red brick technical specifications are generally from 75 to 100. Ordinary fired brick (red brick) is also called standard brick. The size is 240*115*53. (mm) red colour, sometimes dark. Ordinary clay brick has a certain strength and durability, but also because of its porous and has a certain insulation, heat insulation, sound insulation and other advantages. Therefore, it is suitable for wall materials and masonry columns, arches, chimneys, floors and foundations. Old buildings use it as building materials. Invented by the Romans, many of the remaining classical structures in Europe had red brick and brick roofs and walls.
Q: What is the life of an old fashioned refractory brick kiln transformed into a flat topped tunnel kiln? what material should be used to transform the old fashioned refractory bricks vault kiln to flat tunnel kiln, and how long is the service life?
use castable refractory
