Product Description

Refractory Alumina Cement

Description of alumina cement

Refractory cement is a kind of the refractory material use high quality corundum, alumina magnesia spinel and fused magnetite as raw materials, this refractory mate-

rial is characterized of resistance of high temperature, resistance of erode and

emersion, long life used. What's more, it can be made difference kinds of ladle as your request

Q:What is refractory brick?: Capability1. Refractory brick is also known as firebrick. It is faint?yellow or brownish. Refractory brick with 770 ℃ at high temperatures is called for short firebrick. It is mainly used for building and smelting furnace. It is a refractory material made by fring refractory clay or other refractory material.

Q:Does anyone knows which company produces the better refractory materials?: I recommend Xinjiang Yuanyangrefractory material Co., Ltd. Address: Near Xishan Road No.100, Saybagh District,Urumqi. Their products are both in good quality and reasonable price. In addition, there are Xinjiang Zhongwang refractory material factory, Address: Xi hongxi Road No. 769, Urumchi City. They all have a good reputation. You may think about it. 。

Q:What materials are needed to make the amorphous refractory bricks?: I am so glad to answer your question. The amorphous refractory brick is composed of a certain proportion of aggregate and powder, a binder and an additive.

Q:What kind of refractory materials can withstand 1500℃ when processing briquette stove core and meanwhile cost less?: The main material is quartz sand and it is the cheapest, and can resist 1500℃ without any difficulty.

Q:Please answer the questions about the packing and transportation requirements of refractory materials.. Requirements for packing of refractory bricks: Bricks are usually made from pallets.Generally take the automotive, coastal sea city.

Q:Are fire materials poisonous after burning?: High temperature oxide materials in refractory special applications, such as aluminum oxide, lanthanum oxide, beryllium oxide, calcium oxide, zirconium oxide, refractory compounds, such as carbides, nitrides, borides, silicides and sulfides; high temperature composite materials, including metal ceramics, high temperature inorganic coatings and fiber reinforced ceramics.

Q:What is the importance of silicon powder in refractory processing?: it depends on the type of refractory material, in addition to lS friends talked about, in the amorphous mobility&#92 strength should also have an impact

Q:How to divide the materials according to the National Fireproofing Material Standard?: Each country has its own fire safety standards, I do not know which country's standard do you want to know, and each country of fireproof material to the division level is not the same. GB GB 8624, the German standard DIN 4102-1, the British standard BS 476, French standard NF P92 -501 and so on. GB 8624 is Chinese building materials and grade of combustion performance. The information coming form fire resources network (FireTC.

Q:what is best for making refractory insulation for Blast furnace, hot stove.: High dimensional insulating blanket.

Q:whether the aluminum silicate thermal insulation material is fireproof or not?: aluminum silicate is fireproof, and the melting point is between -40 ~ 800 ℃. Aluminum: it takes the flint clay clinker as raw material, produced by resistance or electric arc furnace fusion and injection fiber-forming process. its characteristics: Low thermal conductivity, excellent thermal and chemical stability, without binder and corrosive material.
