Brief introduction:

Refractory materials can be divided into shaped refractory products(Such as: Refractory brick ,Fire clay brick,High alumina brick, Heat insulation brick,Ceramic fiber products ect) andunshaped refractory materials(Such as:Refractory castable, Plastic refractory, High temperature refractory mortar ect), Widely used in metallurgy, petroleum, chemical industry, Cement, Glass, Casting,carbon,building materials, machinery processing, military, etc.

Refractory raw material: The chamotte, Calcined flint clay, Calcined kaolin, Sintered mullite,Bauxite,flint clay, aggregate, fused mullite

Made process:

Made from the natural high quality bauxite, our product is through multi-level homogenozaotpm and then calcined at about 1750 degree. it possesses many good characteristics such as high bulk density, stable quality, good thermal shock resistance, small index of high temperature creep and good resistance to cheamical  corrosion, it is an ideal raw aterial for the following refractory products like a variety of shaped and unshaped refractories, advance ceramic asanitary ware body, precision casting models and so on.


Application: metallurgy, petroleum, chemical industry, building materials, machinery processing, military, etc of thermal technology equipment.

Features: High strength, good thermal stability, impact resistance, scouring resistance, wear resistance, long service life by the combined technology of low cement and adding superfine powder and efficient dispersant. Excellent raw materials and high temperature performance, castable refractoriness reaches 1790 °C. Mixing by machine, convenient construction, the construction period is greatly shortened, and the economic benefit is remarkable.

Purposes: Cement kiln preheater lining, cooling machine lining, pipe lining, coal injection gun wrapping, kiln mouth, and high temperature parts. Prefabricated into various sizes and also can be applied to spraying construction (preheater lining).

Usage: add water to form mortar or make prefabricated block, semi-dry method spraying construction is available for spraying type.

Storage: 25 kg/bag sealed packaging at room temperature for 3 ~ 4 months

Q:Does anyone know the characteristics of refractory for glass kiln?
Refractory is a kind of non-metallic material with refractoriness not less than 1580 ℃, which has better thermal shock resistance and chemical erosion resistance, low heat conductivity coefficient and low expansion coefficient. Refractoriness is the centigrade temperature of refractory cone specimen wiyhout any load resisting high temperatures without melting down Refractory is widely used in industries like metallurgy, chemical, petroleum, machinery manufacturing, silicates, power, etc., which is mostly used in the metallurgical industry, accounting for 50% to 60% of total output.
Q:Is there vermiculite in refractory?
Foreign horticultural vermiculite includes four levels according to the diameter: 3 8mm is No. 1; 2 3mm No. 2, the most commonly used; 1 2mm to No. 3; 0.75 1mm to No. 4, suitable for seed germination. Vermiculite has strong water absorption capacity,
Q:What refractories are resistant to fluorine gas?
It is recommended to use fused-quartz brick, which will produce hydrofluoric acid fluorine (an acidic gas) when water vapors. It is cheap. While it is recommended to use silica brick if it exceeds 1,200 degrees. So acidic refractory is an advisable refractory for using. It works well if the temperature is below 1200 degrees.
Q:Who knows how many kinds of fireproof insulation materials are there in the market?
The so-called A-level materials in fire insulation materials, namely, the WW non-combustible insulation materials, and the WW material s are A-level. Inorganic fireproof and thermal insulation materials can be used as wall insulation materials to replace red bricks, therefore, they, as thermal and cold insulation materials, can reduce the thickness of walls, and save energy, as well as expand applicable areas indirectly, decreased structure weight. They are very good.
Q:How to apply the alumina powder on refractories?
What kind of the refractories can make the aluminium oxide increase the aluminum content and specific gravity, and erosion-resistant.
Q:In entering fire door, which material does well?
Cold rolled steel, or after a flame retardant willow eucalyptus wood, filled up with perlite inside! Fireproof heat insulation. Price is between 300-900, depending on what technology it uses! Company's large-area substrate door (paint) is cheap door, in commonly 350. Followed is without lacquer, which has a layer of decorative materials, generally between 380-500. Finally there is high-grade, which price is around $900. 0...
Q:Could you tell me the fire-resisting time of class B fire proof door?
The fire-resisting time of class B fire proof door is 1h and thickness of door can't be lower than 45mm.
Q:what's the application of fireproofing abs materials?
ABS alloy shell, a toy of child, low load bearing, refrigerator lining, it can be processed into various wear-resisting sheets, plates,and has good electrical performance, it can be used as electronic components or auto parts, all kinds of insulation materials, it's easy to machining on the surface, so it can be made into designated special products (such as electroplate), and easy coloring,
Q:Which refractory quality inspection authority is good?
National testing agencies include National Refractory Inspection Center (i.e. LIRR), China Building Materials Academy (Guanzhuang, Beijing), National Center for Ceramic and Refractory Materials Inspection (Shandong) and China Metallurgical Research Institute (Beijing).
Q:Who knows the highest temperature the high-temperature refractory coating can resist?
The temperature resistance degree of high temperature coating is different according to different coating types. The temperature resistance degree is vary from tens to thousands, magnesia brick: Greater than 2000 degrees dolomite brick: Greater than 2000 degrees casting corundum brick: Greater than 1990 degrees. The above data come from the network, for reference only.
