Product Description
Aluminate cement is a hydraulic cementitious material prepared by calcining aluminum clinker and limestone as raw materials, with calcium aluminate as main component and alumina content of about 50%.
Aluminate cements are often yellow or brown color, and even gray color The main minerals of aluminate cement are calcium monocalcium phosphate (CaO·Al2O3, abbreviated CA) and other aluminates, and a small amount of dicalcium silicate (2CaO·SiO2). The colors are mostly gray and white.

- Q:What refractories have good mechanical property resistance and heat expansion and cold contraction property?
- Aluminium oxide ceramics. I would like to know that what kinds of refractory materials can combine together and what kind of masonry way can be used for these materials so as to achieve the perfect combination.
- Q:Preparation of refractory clay
- Is it to make refractories? Add some andalusite to the refractory mortar will improve the effect.
- Q:Does anyone know the difference between refractory and thermal insulation material?
- The main difference between insulation bricks and refractory bricks are as follows: 1. Insulation effect The heat conductivity cofficient of insulation bricks is usually 0.2-0.4 (average temperature of 350 ± 25 ℃) w / mk while the heat conductivity coefficient of refractory bricks is 1.0 (average temperature of 350 ± 25 ℃) w / mk or more. Thus it can be seen that the insulation effect of insulation bricks is much better than that of refractory bricks. 2. Refractoriness The refractoriness of insulation bricks is generally below 1,400 degrees centigrade while the refractoriness of refractory bricks is above 1,400 degrees centigrade. 3. Density Insulation bricks are generally light-weight insulation material, and the density is generally 0.8-1.0g / cm3. But the density of refractory bricks is above 2.0g / cm3.
- 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:Does the aluminum silicate thermal insulation material fireproof?
- How does its fireproof?performance? this is the material that the decoration master worker recommands to me, how do you think of it?
- Q:What are the types of steel refractory materials
- (1) clay refractory brick (2) high alumina refractory brick
- Q:How many refractory materials does the annual output of 1 million tons of coke oven require?
- The production of dense synthetic Magnesium Oxide requires many steps, briefly summarized as follows:(1) Mgcl2+Ca, Mg (OH) 2, =Mg (OH) 2+CaCl2Sea salt or brine, dolomite, magnesium hydroxide, residual salt(2) Mg (OH) 2 Mg0 (low density);(3) MgO, Mgo (compact)The resulting compact Magnesium Oxide generally has a purity of up to 95%-99%, depending on the manufacturing process and the final application requirements. As shown above, Magnesium Oxide can be obtained from sea water and slaked lime. The density of the final product is through the high temperature roasting in shaft furnace and the large area obtained by calcination, and the mechanical compaction. Through the pre sintered refractory material to fundamentally eliminate the permanent contraction or extension is extremely important, it is obviously, because we cannot expect excessive contraction or extension in the use of the materials can be used to store the proper degree of molten metal or slag. The production of magnesium oxygen throughout the world (Fang Meishi) large factories in the United States, Michigan by brine well production, and by the sea water production Magnesium Oxide factory is located in Florida, Texas, California and Maryland.
- Q:How to solve the shell, the crack problem of refractory material in the process of forming.
- Pressure mode and number of pressure control "spallation". 2, multiple pressure, pressure degree and discharge way: 1, reduce friction, choose appropriate, than big pressure disposable pressure produced by the plastic deformation, allocate reasonable grading, internal and external friction, reduce billet particles and high die wall bright. 4.--- solve the light one firstly. --moisture content being too high easily cause spallation - the compressibility of water is small and have certain elasticity, appropriately to extend the pressuring time is beneficial. The material can produce large plastic deformation under the effect of continuous load. The right amount of lubricant. - body under the condition of less pressure but long effect time molding. Mould structure is reasonable and improve billet natural stacking density. 5.3, measures to improve the unburned brick molding quality. Many times continuously pressure relief is better than one-off sudden unloading, and controlling the appropriate moisture content;- - is beneficial to air overflow.
- Q:How can refractory material of the electric furnace be used for longer.
- I do not know if you are referring to super high power arc furnace for steelmaking, if you are, I have a easy solution for I have been doing this work.
