- Q:What material is used to make furnace pipe of refractory bricks?
- Furnace pipe of refractory brick is an indispensable part of casting cupola. Furnace pipe is divided into upper and lower part. Radial direction and axial breathing. The upper furnace pipe adopts double layer steel structure and countercurrent air supply mode. The lower furnace pipe is made by processing integrated heat resistant steel in flange, fin and inner wall in wearing parts. The operation life is over 3000h. There is radiating rib of heating air on the edge of furnace pipe liner by using the heat of casting cupola to heat air in cupola. Hot air temperature is about 180-250℃, which contributes to improve trhe thermal efficiency of production equipment, decrease production cost and improve economic benefit of enterprises.
- Q:What's the heat conductivity coefficient, specific heat capacity and density of the refractory material of magnesite-chrome brick and magnesia-alumina brick respectively?
- It is suggested that you find some samples of well-known manufacturers, such as Ogilvy and Mather Group, and that will be more correct.
- Q:Who knows what is the external wall thermal insulation materials for level A fireproofing?
- external wall thermal insulation materials level A fireproofing: Incombustible building material is a material that does not occur any burning. Class A1: Monomer inorganic non-combustible. Noncombustible means no open fire. Class A2: Non-flammable organic compound is namely composite materials and non-flammable, the amount of smoke must be qualified. Class B1: nonflammable building material: non-flame material has good flame resistance. It is difficult to fire under the condition of open fire in the air or high temperature, and it is not easy to quickly spread, and when the combustion?source is removed, the combustion will stop immediately. Class B2: combustible?building?materials: flame material has a good flame resistance. In case of fire in the air or at high temperature, it will immediately burst into flames, and easily lead to the spread of fire, such as wooden column, timber roof truss, timber beam and wooden stairs.
- Q:What are the refractory stocks?
- The company produces energy saving, environmental protection type functional refractory materials and unshaped refractory materials. It is the main functional refractory material and unshaped refractory production enterprise in china. Company's products to new green high-quality refractory materials, energy saving and environmental protection as the leading iron and steel industry technological progress and improve the level of technology and equipment to adapt to meet the "development policy" refractories industry to develop industry, has a strong competitive advantage in the market. The main domestic refractory products company can only use part of the products of refractory materials production of iron and steel industry, iron and steel industry production and Pu resistant can be used in the vast majority of refractory products, iron and steel industry with the most complete refractory products. Therefore, the future development of the company is closely related to the prosperity of the iron and steel industry. More than more than 2000 enterprises in refractory industry, the company is the largest supplier of refractory materials in China, and the market share is less than 2%. Iron and steel group integration will inevitably lead to the overall contract cost control, supplier refractory decreases by seventy or eighty to two or three. The company's overall contract accounted for 37% (Montreal 68%), the overall contract increase will enhance the market share and profitability. China's urbanization, industrialization and investment in the 4 trillion infrastructure will stimulate sustained and rapid growth of China's steel demand. Therefore, in the long run, the prospects for the development of refractories for iron and steel are broad.

- Q:Refractory inquiries
- Special refractories are new inorganic non-metallic materials developed on the basis of traditional ceramics and refractory materials.
- Q:What effect does aluminium powder play in refractory bricks?
- Aluminum powder can increase the high melting point of refractory refractory, while increasing material density, hardness and other changes in physical properties of aluminum powder in the application of unshaped refractories in the gas can be discharged in the material, prevent the refractory sudden warming occurred during the burst.
- Q:What's the difference between refractory metal raceway and fireproof raceway?
- In terms of fire protection, fireproof raceway means that it is composed of the material with certain combustion performance and generally made of flame retardant or incombustible?material. While for the refractory raceway, according to GA 479-2004 "Fire Resistant Cable Tray", its most important properties are: Fire resistance of the cable tray should meet with the following requirements: The cable tray of I grade fire resistance should keep the working time more than 60min, of II grade fire resistance should keep the working time more than 45min, and of III grade fire resistance should keep the working time more than 30min. Hope this is helpful for you! Thank you.
- Q:How to distinguish the fire resistant level of construction materials?
- There are 3 conditions for building components to reach fire endurance, namely: Loss of ability to support; loss of integrity; loss of fire insulation function. As long as one condition occurs, fire endurance is reached and the time before it is called fire endurance. 1), loss of ability to support: If the specimen bearing capacity and rigidity reduce, section area shrink, collapses or deformation exceeds specified numerical value because it cannot bear the load of original design under flame or high temperature, it loses the ability to support. 2), loss of integrity: It mainly refers to the thin wall separating component(such as stairs, windows,partitions, ceiling, etc.) burst or partially collapse under flame or high temperature, and penetrating?fracture or opening appears, and the reverse side even burn. For example, when the floor is under flame or at high temperature, the flame spread to the upper room, which indicates that the integrity has been damaged. 3), loss of fire insulation function: It mainly refers to that seperating components loses thermal insulation and excessive heat conduction. In experiment, if the average temperature of component unexposed surface exceeds 140 ℃, or if any spot at the unexposed surface exceed the initial temperature of 180 ℃, the component loses fire insulation function.
- Q:how to use boiler fireclay
- Boiler refractory, diluted with water to touch the places where needed, can be used after high temperature baking.
