Q:Where is the development of refractory industry?: Refractories for continuous casting is an important part of the continuous casting machine, in addition to the characteristics of general refractory material, also for the purification of molten steel and improve the steel quality, stable molten steel temperature and composition, control and regulate the flow of the molten steel and other functions, so it is called functional refractories.

Q:what is the fireproofing material of engine room? who knows it ?: 1. The new type fire?retardant?coating in fire retardant coating, the expanded vermiculite, expanded perlite heat insulation material and cenosphere adiabatic powder, etc. These inorganic component, is a major part of the thick coating type of fireproof coating, and they also are the major factor affecting the level of performance of fireproof coatings. The fireproofing thermal insulation properties of fireproof coating, is mainly determined by the fire back surface temperature of this factor, but also related to the fire endurance. If it reaches the same temperature for a longer time, it shows that it's fireproof thermal insulation is better, and the fire endurance therefore is higher. 2. The new fireproof board new fireproof board now is welcomed by the people and the important factor is its environmental protection, and with the increasing high-rise buildings, the fire protection requirements and strength requirements are also rising, it is a big challenge for the performance and standard of the fireproof board.. Now fireproof board is mainly used siliceous material or calcareous materials, and then mixed with the fiber material, lightweight aggregate, adhesives and chemical additives, it is not only be fireproofing, but also improve their thermal insulation performance, and light weight, good carrying capacity, good durability, no aging problem, more importantly, it is good in environmental protection.

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 are the refractories for converter?: Permanent layer (sintering) magnesia brick, the working lining gunning material for the working layer and the permanent layer gap, using magnesia ramming materials, MgO-C brick brick supply,

Q:what materials can make external wall fireproofing paint have the fireproofing effect: First, the width of fire barrier is greater than 30CM, and the thickness should be same to the thickness of insulation material. fire barrier zone insulation board must do the whole area sticking construction with the base wall during the construction. fire barrier zone insulation board is required to assistant binding by anchor bolt, anchor bolt must suppress the underlying mesh. fire barrier zone should be set at the upper position of door and window openings, the distance between the low edge of isolation belt and the upper edge of the window must be less than 50cm. When the fire barrier zone is set on the edge of the window, fire barrier zone at the upper part of the window should do flanging when sticking, flanging glass fiber mesh must exceed 10CM than firebreak insulation board. flanging network, underlying network and surface network can not be overlapped or butted at the top of the window. the thermal resistance of fire barrier zone must be half than EIFS thermal resistance in the cold northern areas, while the thermal resistance of fire barrier zone must be three times than EIFS thermal resistance in the hot summer and cold winter area. Cement foam insulation board is recommended to use as external insulation board materials, level A exterior wall cement foam insulation board is a new ultra-lightweight thermal insulation material, with the advantages of lightweight concrete and insulation performance, with characteristics of low production costs, simple process, easy to operate, small product density in 180250kg / m3, high strength, low water absorption and good insulation properties, thermal conductivity of 0.05 ~ 0.07W / m · K and level A non-combustible; it is suitable for external wall insulation and fire isolation belt, and can meet the urgent needs of the market of exterior thermal insulation. With the increase of the intensity of the building fireproofing, the products will become the leading products in building insulation market in the future.

Q:What are the material requirements of class A fire resistant door ?: What are the material requirements of class A fire resistant door ?

Q:The development prospect of fire-resistant material: Concrete has a broad employment direction while refractory material is not in popular demand. But if you do well, you are one of ethe experts.

Q:what is the requirements of roofing insulation materials fire rating?: The fireproofing requirements of architectural design are regulated by architectural design fire?safety?rules, roofing insulation material only has the requirements of materials combustion performance, namely non-combustible material. No fire rating requirements.

Q:Which refractory is better for building 1500 degree kiln ?: The top and wall use alumina hollow ball brick. If it is cubic kiln, the kiln bottom should use heavy corundum brick. If it is continuous kiln, burning zone should use alumina hollow ball brick, burning zone seal and kiln car face brick. If it is pit furnace, curved seal should use heavy corundum brick, and furnace wall and top should use alumina hollow ball brick. That depends on what kind of kiln it is. Curved seal and kiln car should use heavy corundum brick. You can add me friends to have further talks.
