Q:How to test the aluminium bricks of high alumina refractory bricks?

Before making bricks, the raw materials are usually tested and tested to see if the aluminum content is up to standard

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 materials are used for roof insulation?

There are two kinds: one is a kind of cotton insulation board, such as rock wool board, aluminum silicate cotton board, but this is not environmental protection, harmful to life, foam board (this fire safety factor minimum), these relatively cheap.

Q:How to reduce the harm caused by two times mullite in high alumina refractory material

Prolong the sintering time and adjust the aluminum content of the high alumina brick.

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:Can high alumina brick resist carburizing?

The key is to look at the content of Fe3O2 metal oxides (so-called anti carburizing brick generally refers to the content of Fe3O2 less than 1% clay brick and Gao Lvzhuan) just a photo shoot, out for everyone to see, high alumina brick common in reductive atmosphere has been chalking up.

Q:What is the heat preservation material used in a laboratory furnace?

Silicon carbide (SiC) is made from quartz sand, petroleum coke (or coal tar), sawdust (green salt produced when adding green silicon carbide) and other raw materials by smelting with resistance furnace at high temperature. Silicon carbide also rare minerals in nature, Mo sangshi. Silicon carbide, also known as carbon silica. Silicon carbide is the most widely used and the most economical kind of refractory materials in C, N, B and other non oxide refractory materials. It can be called "carborundum sand" or "refractory sand".

Q:What is the price of the first grade high alumina brick?

The specifications and different prices, relatively large fluctuations of the main push of the refractory Dongxin high alumina brick high alumina brick prices generally around 3000 have various levels of Dongxin refractories

Q:Density of high alumina bricks

The density of high alumina bricks is determined according to the price. The average density is between 2.3-2.5g/cm3. The higher the density, the higher the price, the higher the aluminum bricks are in the industry. More than 2.4 are required.
