- Q: is it correct that the higher the refractoriness is, the better refractory bricks are?
- Does not necessarily, it has a great relationship with the compression and bending and corrosion resistance.
- Q: What's the difference between a high aluminum brick and a clay brick, two?
- Lightweight high alumina bricks are usually made of high alumina bauxite clinker with a small amount of clay. After grinding, the bricks are poured and shaped in the form of slurry by gas or foam method. They are fired at 1300~1500 DEG C. Sometimes industrial alumina can be used instead of some bauxite clinker. Used for lining and insulation of masonry kilns, as well as for areas where there is no strong, high temperature molten material erosion and erosion. When contacting the flame directly, the surface contact temperature shall not be higher than 1350 degrees centigrade.
- Q: Refractory brick, high alumina brick, magnesia chrome brick, magnesia brick, clay brick, which type of brick has the highest refractory temperature?
- It depends. if high alumina brick is used in kiln, its temperature is above 1700 degree, clay brick is between 1500 degree to 1750 degree, magnesia bricks and magnesia-chrome bricks are about 1500 degree to 1650 degree.
- Q: Is there any special requirements for the building blocks of the smoke and gas wells, how about the refractory bricks?
- There are no special requirements. Not necessarily need refractory bricks, red bricks are ok. The building size of the flue is according to the smoke exhaust rate.
- Q: What are the disadvantages of sintered clay bricks?
- Fired common bricks are made of clay, shale, coal gangue or fly ash as raw materials, and the solid or hole ratio after roasting is not greater than the specified value, and the size of the bricks meets the requirements.
- Q: th choose of different refractory bricks in the rotary?kiln
- According to the characteristics of each belt, magnesium chromium brick. Take the most kiln foe example, the configuration of kiln refractory is not the same, the burning of the product is not the same. there are many kinds of rotary kiln. magnesia bricks are generally used in high temperature zone, anti-stripping alumina brick,silmo brick are used in temperate zone, clay brick is mainly used in low temperature zone. generally inlet and the outlet use corundum mullite, wear-resistant castable, spinel brick,etc. select brick of proper performance, but also take into account the economy
- Q: The boiler is divided into several categories according to the structure, what characteristics does each have?
- package boiler and assemble boiler are divided into vertical boiler and horizontal boiler. Vertical boiler. Assembled boiler adapts to boiler more than 6 tons, the package adapts to boiler less than 10 tons.
- Q: how to test the high alumina refractory brick mixed alumina?
- The first thing before producing bricks is to test whether the aluminum content reaches the standards, general testing on raw materials. Second: the shaped high aluminum brick will be tested in some professional equipment, you can know it from the professional inspection departments.
- Q: How many bricks, mortar and how much wear and tear does one side of the clay brick masonry need?
- In the standard brick wall of 1M3, the standard brick occupies 516.53 pieces of *0.24M*0.12M*.053M=0.788M3
- Q: Why is there cracks in the use of refractory bricks?
- Several reasons for the emergence of cracks: (1) temperature difference stress (2) mechanical stress (3) crystal type change stress
