Q:The difference between clay bricks and clay bricks?
Clay brick is a small building with artificial bulk. Also called sintered brick. Solid clay brick is one of the oldest building materials in the world. It is a building material that is loved by the people.
Q:What type of refractory brick won't deform or crackbe for a long time in the temprature of about 1600 degrees?
1. , mullite poly light ball brick type, andalusite brick type: MJ-1600 MJ-1700 the temperature is higher than 1600 C. 3, the refractory bricks that won't deform or crack in the 1600 degrees Celsius for a long time includs the following several commonly used bricks: GMZ-80 GMZ-75 the temperature is higher than 1650 DEG C, 2, corundum mullite brick type
Q:Does circulating fluidized bed boiler's furnace wall use refractory to have thermal insulation?
Now all use castable refractory, the outer layer is generally pouring refractory castable, the inside layer is a heat insulation castable refractory.
Q:The matching ratio of masonrying refractory bricks cement
When building refractory bricks, use matching chamotte, do not use cement
Q:What are the factors that determine the weight of the refractory bricks?
(5) Under high temperature, the volume is stable, the inner part of brick will produce unrecoverable volume shrinkage or expansion because of the internal transformation. Therefore, masonry inner will produce stress to make the material break and peel off, and the weight of a ton of bricks is determined by the bulk density and quantity, how much is the weight of refractory bricks, refractory bricks should have the ability to resist the damage, the weight of a piece of brick is determined by the bulk density: Refractory bricks are used under high temperature for a long term: Refractory bricks in the use of the process. Cooltech refractory brick used in various high-temperature equipment: The temperature of some parts of metallurgical furnace and other industrial furnace is uneven due to rapid temperature change during operation. (3) good thermal stability: Refractory bricks should not only have a high fusion temperature, no softening deformation and collapse, causing damage to the masonry. (4) strong resistance to slag: Modern metallurgy and the other industrial furnace heating temperature is generally between l000~1800. Refractory bricks should have the performance that is not easy to melt under high temperature. Therefore. Therefore, it is subject to high temperature conditions of physical and chemical corrosion and mechanical damage, the refractory brick must have the ability to resist high temperature chemical corrosion, the volume of refractory brick is required to be stable under high temperature. (2) High-temperature structural strength, chemical corrosion of metal, but also should have been built in the stove brickwork load or other mechanical vibration, often has the high temperature slag, so the refractory materials performance should meet the following requirements: (1) high refractoriness
Q:Whether yellow dextrin is used in refractory bricks?
The production of refractory bricks needs yellow dextrin as bonded materials.
Q:does all the refractory refer to refractory bricks when making steel?
Not only are refractory bricks, and shapeless refractory material; blowing agents, drainage sand, and oxygen are all metallurgical auxiliary materials.
Q:What are the differences between sintered bricks and refractory bricks?
Sintered bricks belong to a type of refractory bricks.
Q:What is the density of the high alumina refractory brick?
it depends on the aluminum content, the higher it contains, the larger the density is. the hjghest is 3, the lowest is 2.
Q:How much is the silica powder in refractory bricks.
It's not easy to construct, also need to consider the technical and economic indexes, DH3, 1 kg silica powder replaces 1 ~ 3 kg cement, which is the reason why silicon powder was not used and spreaded in concrete in past, choose some silica power fume. In general, with the smoke escaping by special capture device for collecting and processing To determine the mixing method of silica powder, when mixing silica powder, you should find out the optimal dosage in order to obtain the best results, as the study, the content is 5% ~ 30%, H, the mixing of super high strength concrete, use same amount of silicon powder to replace equal cement to main same fluidity, Microsilica or Silica Fume, it is mainly according to the design requirements, and does not reduce the amount of cement, sand and stone to adjust the optimal dosage of water reducer, when deciding the best mixing amount of silica fume, the concrete is too sticky, most use naphthalene water reducing agent.
