Q:What's the price of high alumina refractory bricks?

The price of high alumina refractory bricks varies greatly according to the content of AL2O3.

Q:What does refractory consist of?

Refractory materials can be divided into main raw materials and auxiliary raw materials according to their function in the production process of refractory materials.The main raw material is the main body of refractory. Auxiliary raw materials can be divided into binders and additives. The role of bonding agent is to make the refractory body in the production and use process has enough strength. There are commonly used lignin, phenolic resin, asphalt, cement, water glass, phosphoric acid and phosphate, sulfate, some main raw material itself has the effect of binder, such as clay; additive is to improve the production of refractory materials and construction technology, or strengthen the refractory material of some properties, such as stabilizer, water reducing agent, inhibitor, plasticizer, foaming agent, dispersing agent, bulking agent, antioxidant.

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

There must be a difference. They vary in color from the amount of aluminum, the weight, the temperature, and the color. For example: 75 high aluminum and 43 clay bricks, 75 single weight 4.5kg or more. 43 3.65kg or so, the use of temperature 75, high aluminum in about 1520, 43 of brick 1430 or so, the color of 75 pan white, 43 of the Loess color. In short, the difference is great.

Q:What are the reasons for the decline in the performance of high alumina bricks when we use high alumina refractory bricks?

The brick Pei boring and time. 6, Pei brick kiln installed between the brick and the brick Pei order, Pei and kiln top, kiln wall gap etc.. 7, high alumina brick kiln plan, and the lack of edges and corners of the scene should be avoided.

Q:How are the grades of high alumina bricks differentiated?

High alumina brick: aluminium silicate refractory product with a content of three Al2O3 (two) and more than 48%

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 refractory material does cupola lining use?

It's made of high quality refractory material: 1770 ~ 2000 centigrade.

Q:Aluminum content 38, silicon content 55 What refractory bricks?

Hello Only on behalf of the Zhengzhou colt as refractory product index your answer to this question is not entirely separate from the chemical index of aluminum content, silicon content and judgment, personally think that three types of refractory bricks may respectively is: Two: semisilica brick high alumina brick

Q:The difference between clay bricks and clay bricks

According to the hole rate: solid brick (no hole or hole rate less than 25% bricks), porous brick (hole rate is equal to or greater than 25%), the size of the hole is small and the number of bricks, usually used in load-bearing parts, higher strength level. Hollow brick (hole rate equal to or greater than 40%, large pore size and small amount of brick, commonly used in non load parts, low strength grade).Solid bricks and porous bricks are mostly used for load-bearing structural walls. Hollow bricks are mostly used in non load bearing structures.

Q:How many cubic bricks does a high alumina brick have?

Different content of aluminum, different proportion, weight is not the same. General grade T3 standard brick, 4.3~4.5kg, aluminium content 75. T3 size 230*114*65mm.
