High Temperature Castable Refractory Cement
Product Description
Refractoriness of not less than 1580 °C cement. According to the composition of different can be divided into low calcium aluminate refractory cement, calcium aluminate cement, calcium aluminate cement and dolomite refractory cement. It can be used for various refractory cement cement refractory aggregate (such as corundum, Calcined Bauxite,etc.) made of refractory mortar or concrete, used in cement rotary kiln and other industrial furnace lining.
Specifications
Refractory cement lining baking, must pay attention to the following matters:
1) at room temperature 350 degrees, most likely caused by local spalling, special attention should be paid to slow baked. As in the 350 degree heat preservation is still a lot of steam coming out, still should slow heating rate.
2) in poor ventilation, water is not easy to discharge conditions, to extend the preservation time.
3) when using heavy oil for baking, to prevent oil spray on the lining surface, to prevent local burst.
4) when using firewood baked, direct contact with the flame is often caused by local heating too fast, should be protected.
5) on refractory cement pouring, at least by 3D after baking.
6) for refractory cement lining cooling slowly, avoid the forced ventilation.

- Q:how about the performance of aluminum silicate fire proof thermal insulation?
- aluminum silicate fire proof thermal insulation board has a good performance. it is a artificial board that separates the wood and plant fiber by mechanical and chemical methods and mixed the adhesion agent and water-proofing?agent, molding by high temperature and high press. the density of fiber. tha above information is coming from the Internet and it is just for reference.
- Q:What are the filling refractories in door leaf of class A fire resistant door?
- Magnesium chloride, magnesium oxide, perlite and other mixtures.
- Q:What are the standards of refractory concrete ?
- Heat-resistant concrete refers to the kind of concrete which remain undamaged, do not lose the necessary bearing capacity at 200 ~ 1300 ℃ high temperature for long term, and still maintain its physical and mechanical properties.
- Q:what is the material of fixed first rate fire resistant window?
- Fixed first rate fire resistant window is produced by the steel sash windows, steel casement, fireproofing glass. Fireproof windows, is composed by steel window frame, steel casement, fire-proofing glass. it refers to the window which can isolate and stop the fire spreading. The fire window product is named after the main material of window frame and the window casement, window frames is made of steel, casement is made of wood or the sash frame is made of wood and the casement is made of fire window.
- Q:Who know about the knowledge of acid refractory material? Please explain in detail.
- Abrasion resistance of fire resistance material depends on the material group and structural material. The abrasion resistance of dense single crystal materials depends on the hardness of mineral crystal. The higher the hardness, the more resistance the material is to abrasion. non mineral crystals with fine grain material has a high wear resistance. The abrasion resistance of materials is related to bulk density or porosity. Aluminium refractory material can resist a temperature as high as 700~900 degree within the elastic range. The higher the temperature, the lower the resistance. Abrasion resistance will be increased with elastic modulus as temperature increase. In many cases, refractory material will often cause a lot of harm due to mechanical abrasion.
- Q:How to understand qualitative and qualitative refractory materials?
- Such as amorphous refractory castable, referred to as bulk loading, cast material, ramming material, refractory clay etc., utensils and other special products. Amorphous refractory material products, refractory heat insulating bricks and experimental and industrial crucible, spraying materials, such as burning bricks, electric melting brick, turn it into required shape and process heat treatment in where it is used.
- Q:I wanna ask what are the acidic refractories?
- (1) silica?brick with stronge acidity, unshaped silicious refractory, quartz glass and fused silica combined products; (2) semi-silica refractory with moderate acidity and pyrophyllite refractory; (3) clay-based refractory with weak acidity.
- Q:What are the materials of white firebricks?
- The commonly-used firebricks include alumina bricks, corundum bricks, chamotte bricks, high alumina bricks, diatomite bricks, zircon bricks, lightweight corundum bricks, zirconia bubble bricks and so on ~~~
- Q:What's the difference of fire-resistant material's density, specific gravity and bulk specific gravity?
- glass
- Q:What is the difference between the fire?rating and the fire resistant level of the fire-fighting equipment?
- Fire rating and fire-fighting rating are the misnomer to the building fire resistant level. The building fire risk is measured by fire resistant level. The article 3.2.1 and 5.1.7 of "Architectural design code for fire protection" have made provision respectively on the fire resistant level of plant (the storeroom) and civil construction. Article 3.0.2 of "Code for fire protection design of tall buildings" has made provisions on the fire resistant level of tall buildings. As for the warehouse building "category malonate", it refers to one of the fire risk of goods storage, which is divided into A, B, C, D, E, and each category is refined depending on the nature of different substances. "Malonate class" specified in article 3.1.3 of "building design for fire protection" refers to the flammable solid.
