Q:How much is the bending temperature aluminum silicon carbide brick for torpedo car

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

Q:What is the difference between corundum and high alumina??

The main component of high purity 99 corundum brick is corundum sand,90 corundum brick is mainly composed of corundum sand and a small amount of Suzhou soil, mullite.

Q:How to distinguish the good or bad of the high aluminum brick?

In the procurement of high alumina brick, the first color, high quality aluminum brick, brick surface smooth, yellow color pale, four sides equal, no broken angle, no cracks.

Q:What are the high aluminum bricks made of?

The amount of refractory mud accounts for about 6% of the brick weight

Q:What are ordinary bricks, refractory bricks, hollow bricks?

Hollow brick is divided into cement hollow brick, clay hollow brick, shale hollow brick. In March 2011 Yunnan Yingjiang earthquake occurred in 5.8, the use of cement hollow brick houses collapsed and killed several people, due to safety concerns that Yunnan intends to disable the cement brick, Shandong Qingdao in the construction of real estate has also been halted the use of cement hollow brick. Professional claims in the construction industry argue that the prohibition of the use of such statements is unscientific and unprofessional. Misleading the public, it must be corrected. Hollow brick is only a kind of building material, and it is no problem to use it in scientific way. Hollow brick in use is very scientific, high quality requirements, the investigation of the foundation is suitable for the use of hollow bricks, how to design, construction, cement and other related ingredients, there are no problems. According to strict procedures, scientific use, strict implementation of relevant national standards, the use of qualified hollow bricks, there is no problem. Similarly, if the use of solid bricks does not strictly comply with the relevant standards of the state, the same will be a problem.

Q:What is the difference between high alumina brick and clay brick?

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:What kind of material is the general metal case?

Ordinary computer chassis and the material itself does not produce high-energy radiation, only in the space environment of the computer is the external defense requirements, and in the space structure, the use of lead as protective materials, unbearable weight.

Q:What is the standard size of high alumina brick?

The country has laid down a number of criteria for the use of refractory bricks to unify market demand.

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 are the high temperature refractory mortars made of?

Products used in metallurgy, building materials, machinery, chemical, power industry, industrial thermal furnace, for masonryBuilding clay brick, high alumina brick and corundum brick have the characteristics of full grey seam, good airtightness, high bonding strength, high temperature performance and suitable construction time
