High alumina brick with unique advanced technology, the temperature of refractoriness under load is normally above 1420~1550°C , which is higher than the fireclay brick and it increases along with the AL2O3 content enhances.
Characteristices of high alumina brick
1. High intensity for pressure
2. Good thermal shock stability
3. Strong abrasion and corrosion resistance
4. High cold crushing strength
5. Excellent abrasion resistance at cold and hot conditions
Advantages of high alumina brick
Good ability of anti-acidity, anti-metal fluid corrode and anti-oxidation.
Applications of high alumina brick
1. Lower the heat capacity of the furnace
2. Used normally in industry furnaces such as Blast furnace, hot-blast furnace and EAF etc
- Q: What are the high aluminum bricks made of?
- It's OK to use corundum bricks and alumina hollow ball bricks to build a furnace,
- Q: How much is one ton of high alumina refractory brick?
- Three high aluminum refractory brick Zhengzhou Kuwait is generally around 800. 32 years of experience, good.
- Q: What are the requirements for Rubble backfill height?
- 1, filling thickness is not greater than 50cm.2, filling, the use of layered filling.
- Q: What is the content of free silica in the refractory bricks of high alumina bricks?
- In the meantime, the free silica content of silicon brick is as high as 90% above. Therefore, the most serious damage is silicon brick, followed by clay brick, high alumina brick, magnesia brick and so on.
- Q: Which is faster for heat transfer between corundum bricks and high alumina bricks?
- There must be a difference. They vary in color from the amount of aluminum, the weight, the temperature, and the color.
- Q: What kinds of minerals are there in the five major categories of ore crystal chemistry?
- Natural element minerals. Of minerals produced by an element (elementary substance). There are about 90 natural elements in the earth's crust, accounting for 0.1% of the total weight of the earth's crust. Can be divided into metal elements, mainly platinum and copper, silver, gold, etc., non-metallic elements, carbon, sulfur, etc., half metallic elements, arsenic, bismuth and so on.
- Q: Corundum, high alumina and fireclay refractory difference is what
- Corundum is unknown. The high alumina brick has higher aluminum content than the clay brick, and the temperature resistance is higher than 300 degrees. It is more durable and durable than the clay brick. The production process of high alumina brick is better than that of clay brick. For example, the weight of good clay brick is 3.7kg, and that of high alumina is 4.2kg. Good density. But the price of high aluminum is too high: ordinary clay brick (standard brick example) in 1.1--2.5 yuan / block, high aluminum to 4.5 yuan / block, or even more expensive. The extra high aluminum has reached 5000 tons. Say straight white point is: under the same conditions, clay brick for a period of one year, then the high aluminum for more than three years.
- Q: Are there any differences between insulating bricks and refractory bricks?
- The insulation performance of thermal conductivity of insulating brick in general 0.2-0.4 (average temperature 350 - 25 DEG C) w/m.k, and the thermal conductivity of refractory brick in 1 (the average temperature of 350 - 25 DEG C) above w/m.k, which can obtain the insulation performance of insulating brick than refractory brick insulation performance is much better.
- Q: What are the requirements for refractory materials in heat treatment furnace?
- Refractoriness is the property of a refractory against high temperature, which means the temperature at which a refractory is softened to some extent after heating, but not its melting point. According to the degree of refractory, refractory materials can be divided into: General refractories, refractory degree is 1580 to 1770 DEG C; advanced refractories, refractory degree is 1770 to 2000 DEG C; special refractory material, refractory degree is greater than 2000 DEG C.
- Q: What are the lining structures of lime rotary kilns and what are the requirements for refractories?
- The current configuration of domestic calcining active lime rotary kiln refractories are as follows: the discharge end of low cement high alumina castable with 3% steel fiber; the cooling zone and the firing zone: dry magnesia spinel brick with high aluminum brick with high temperature; preheating: high alumina brick; low temperature preheating zone: clay brick light clay brick; feeding end: low cement high alumina castable with 3% steel fiber; in addition, brick size also have the corresponding requirements; dimensional tolerances: dimensional tolerances used in different parts of the requirements are not the same, the general control in 2mm; corner damage: general permit edge damage 40mm and 5mm deep within angle loss in the hot and cold surface is allowed to have only one, three edges and the length of not more than 50mm; there are cracks parallel to the use of surface crack is not allowed, cracks of brick surface are allowed.
