Q:How does the physicochemical index change when the high alumina brick is used at high temperature?

When the high alumina brick is used at high temperature, the physical and chemical indexes and other constants will not change if the temperature is in the physical and chemical indexes and the softening temperature of the load.

Q:What is the difference between fireclay bricks and high alumina refractory bricks?

First of all, there is a difference in the material, one is clay, and one is high aluminum.Also known as clay brick brick, is a man-made small bulk building, clay brick clay (including shale, coal gangue powder) as the main raw material, through mud processing, molding, drying and roasting, solid and hollow.

Q:What are the specifications for bricks?

In a proper ratio of lime sand brick and quartz sand, sand or fine sand, the ground, Kazumi Wa, semi dry pressing and autoclaved curing and. The fly ash brick is made of fly ash as main raw material and mixed with cement material such as coal gangue, stone powder or clay. It is made up of batching, molding, drying and roasting. It can make full use of industrial waste residue and save fuel.

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:What's the difference between high alumina refractory bricks and high alumina refractory bricks?

The chemical pH value of high alumina refractory brick belongs to neutral and alkaline refractory brick, and clay refractory brick belongs to neutral and acid refractory brick.

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:Which thermal shock stability of clay brick and high alumina brick is good?

High alumina brick is made of superfine alumina, fused corundum and fused mullite as main refractory materials.

Q:What is the apparent porosity of high alumina brick?

In the production of high alumina bricks in addition to the entity, there are many different sizes and shapes of different pores, pores can be divided into three categories: one side closed the other side and the outside world is called open pores, closed in the product not communicated with the outside is called closed pores, penetrating through pores called the few products.

Q:What should be used as binder for making high alumina bricks?

Bond for making high alumina brick: soft clay has good plasticity, so the high alumina brick is usually made of soft clay as bond. However, the free Al2O3 free SiO2 and bauxite clinker clay in under 1200 degrees occurred two times of Mullization reaction, generate large volume expansion, silicon porosity, strength reduction. Therefore, the amount of clay powder in the ingredient should be no more than 5%.

Q:What causes breakage of refractory bricks?

There are many factors that lead to the damage of refractory brick, can be divided into: the chemical loss (e.g. salt penetration, redox phenomenon), heat loss (burning, thermal shock), mechanical loss (kiln deformation, thrust, brick masonry quality etc.).
