Product Description

 Alumina cement, also called as pure calcium alumina cements, are produced by calcining industrial aluminium oxide and fine limestone under strict mineralogical control in rotary kilns into clinker, cooling and then grinding in ball mills. The excellent rheological properties make alumina cement suitable to formulate the top grade and high-temperature-resistant low cement and ultra low cement castables. It is an absolutely necessarilly excellent hydraulic binder used in refractory materials for high temperature equipments in the area of metallurgy, chemistry,building material and fire-electricity applications.

Q:who knows the requirements of refractory for forge furnace?
Forging heating furnace working temperatures above 1000 ° C, reasonably choosing refractory for build furnace has an important meaning for guaranteeing the normal operation of the heating furnace, improving the service life of furnace and energy saving. refractory is generally required to have the following properities: 1, it should be equipped with the properity of no deformation and melting under certain temperature. 2, it should be equipped with the neccessary structural strength without softening deformation in high temperature. 3, volume stability at high temperature, brick body won't be deformation or cracked due to expansion and contraction; 4, not broken and peel off under rapid changes of temperature or uneven heating; 5, resistant to chemical erosion of molten metal, slag and furnace gas,etc.
Q:what's the materials of fireproof housing?
what's the materials of fireproof housing? what's the fire rating? how much is it? What are the key installation points?
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:Why the corundum can be used as refractory
Because the main component of corundum is aluminum oxide!
Q:Which basic refractory is better?
Zhengzhou Xindeyuan Refractories Co., Ltd.and Zhengzhou Rongsheng Kiln Refractories cO.,Ltd. Their basic refractories mainly refer to refractories with magnesium oxide and calcium oxide as main components what can resist errosion of basic slag, including magnesia bricks, magnesia-alumina bricks, magnesia-chrome bricks, dolomite bricka and so on(magnesia bricks), among which magnesia bricks is the most common. Magnesia brick containing more than 80% to 85% magnesium oxide, has good resistance to basic slag and iron slag, and higher refractoriness than clay and silica brick. It is mainly used for open-hearth furnace, oxygen-blown converter, electric furnace, ferrous metal smelting equipment and other high temperature equipments.
Q:What is the principal part of silicious refractory material
blast furnace hot blast stove and ceramic tunnel kiln vault, etc., the softening temperature under a fixed load is high (1690-1710 degree), glass melting furnace, lightweight silica bricks and generally the silicon dioxide is greater than 93% and used above the 600 degree. I had undertaken to complete the 50,000 tons over two advanced silica brick production line design. It is a typical acidic refractory. At present, it is mainly used to coke oven which the masonry operating temperature is higher than 600 degree, with good acid resistance of slag erosion, including silica brick, good thermal conductivity, high thermal vibration stability, product with fused quartz, close to its refractoriness silicious refractory SiO2 which is as the main component of refractory products.
Q:How is grade of fire endurance divided?
You can search the answer on the Internet, thank you!
Q:What is the definition and classification of amorphous fire resistance materials?
9.8. brick made of refractory bone material and powder material can be used directly or after adding appropriate liquid formulation Refractory paint. Refractory slinging material 6. Prefabricated cubes, bonding agent or other additives. fire-resistance sparying material compround additives. Refractory pressed into the material, binder. Refractory ramming material 3, The material is a new fire proof material without calcination Heavy aggregate and lightweight aggregate: Inorganic binding agent and organic bond, its fire resistance is not less than 1580. Refractory castables 2 mouldable refractory Classification according to the type of bonding agent: 1. Classification according to refractory aggregate. According to the production and construction method, refractory mud or refractory mire, with a certain proportion of the mixture
Q:Can polystyrene foam color steel plate be used as decorative fireproofing material ?
As far as I am concerned, polystyrene foam color steel plate cannot be used as decorative fireproofing material. Because polystyrene flame retardant and non-flame retardant of the points, from the fire retardant is generally self-extinguishing. Polystyrene is the polymer synthesized by styrene monomer through free radicals polycondensation reaction. It is a transparent thermoplastic plastic. With above 100 ℃ glass transfering temperature,it is often used to make a variety of disposable container and disposable foam lunch box which have to withstand the boiling water temperature.
Q:Is there anyone who can explain how to grade the level of fire insulation board?
1, Combustion performance of building material is divided into the following several class according to China's national standard GB8624-97 Class a: Non combustible building materials: Non-conbustible material. Class B1: Refractory building materials: Flame retardant materials have good flame retardant effect. It hardly catch on fire in the case of open flame and high temperature, do not spread fire quickly, and when the fire source is removed, fire will be stopped immediately. Class B2: Combustible building materials: Combustible materials have certain flame retardant effect. In case of fire or under high temperature, it will immediately burst into flames, easily leading to spread of fire , such as poles, wooden frame, timber, and wood stairs. Class B3: Combustible building materials: Without any flame retardant effect, will be burnt easily, resulting in high risk of fire. I Hope my answer will help you.
