What is the details of our grog brick?

1.Made by bauxite clinker and binder through Crushing,Mixing,Shaping,Drying and high temperature Sintering.

2.Al2O3 content is 48%-80%.

3.Main mineral components are corundum and mullite phases.

4.Refractoriness is usually above 1770°C,refractoriness under load is 1420-1550°C.It is a neutral refractory material so that it enjoys excellent resistance to acid and alkali corrosion.

5.Working temperature:1350°C -1650°C.

Q:What are the high aluminum bricks made of?
We specialize in the production of various LeiBao refractory refractory material, such as corundum, zirconia products, alumina hollow ball products, mullite products and so on.
Q:How does the physicochemical index change when the high alumina brick is used at high temperature?
If the range of softening temperature exceeds the load, the constants of other physical and chemical indexes will also increase or decrease.
Q:Refractory brick, high alumina brick, magnesia chrome brick or magnesia brick, clay brick, which type of high temperature refractory brick?
The super high alumina brick in high alumina refractory brick has the highest refractoriness, and the corresponding production cost is higher.
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 price of the latest thermal insulation material?
Also through online pre understand the products and prices, and now have large-scale manufacturers are generally opened on the cable business. Goods than three, manufacturers on-site inspection, confirm the quality of goods after considering cooperation.
Q:What is the standard classification of high alumina bricks or high alumina bricks?
High alumina brick is one of refractory materials. The main component of this kind of refractory brick is AL2O3. High alumina brick refractory clay brick and brick than refractoriness to high. It belongs to high refractory. High alumina brick Al2O3 more, close to the neutral refractory material, can resist acid slag and alkaline slag erosion, because it contains SiO2, so the ability of alkaline slag resistance than acid resistant slag ability is weaker.According to the number of AL2O3 content is divided into, 55,65, 75,80 and so on several grades.
Q:What is the difference between metal compounds and metal solid solutions?
A series of intermetallic compounds occurring between transition metals in intermetallic compounds. The most important are L sigma sigma phase and ves phase, they are topologically close packed (TcP) phase, they consist of a small atomic radius of a dense layer, which is inlaid with a large atomic radius of atomic structure, this is a highly dense pile. In addition to atomic size factors, their formation is also influenced by the concentration of electrons.
Q:How to make refractory bricks and boiler wall adhesion more firm?
If the condition, the user heat-resistant steel welding grip nails, expansion joints can not be too big.. Also to use high temperature aluminum brick, high temperature resistance, but also to extend its use cycle.
Q:Corundum, high alumina and fireclay refractory difference is what
In fact, they are not consistent with raw materials, corundum refractories can use white corundum, white corundum, brown corundum corundum material, alumina content of these materials is higher than 90%, while the high aluminum refractory material is bauxite, alumina in 90 to less than 70, and clay raw materials the aluminum content is less than 70..
Q:How high can aluminum bricks expand at 80O degrees of heat?
When an object is heated, the particle moves faster and thus occupies additional space. This phenomenon is called dilation.
