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 are the electrical fire protection materials?: Electrical fire protection materials are the following: 1, fire proof board It is the most commonly used materials in the market, which has the advantages of fire prevention, moisture, abrasion, oil, easiness to clean, and more varieties of colors. Installed in the building exit corridors, stairs and corridors, such as fire ceiling ceiling, it can ensure that people can be evacuated safely, and to protect people from the spread of the fire. 2, fire proof door, fire proof door is divided into wooden fire door, steel fire door and stainless steel fire door. Fire proof doors are usually used for the opening of the firewall, the entrance of the staircase, the evacuation of the aisle, the openings and other parts of the pipeline, the fire prevention, playing an important role in reducing the loss of fire. 3, fire shutter It can be set in the location where it is not convient to install a fire proof wall, fire shutter generally has functions such as good fire resistance, heat insulation, smoke, compression, anti aging, wear and corrosion. 4, fireproof and mothproof wood fire wood moth is made by putting ordinary wood into the solution containing calcium and aluminum, and then into the solution containing phosphate and silicate. In this way, two ion will be undergong chemical reaction in the wood, forming materials similar to the ceramic, and filling the gap of cells and tissues, so that allowing it to have fireproof and mothproof performance.

Q:What is the limit of fireproof rolling shutter?: According to the national standard 14102-2005 GB standard, the provisions of 14102-2005 GB specify that: According to provision 14102-2005 GB: If fire resistance limit of fire resisting shutter is no less than 3 hours, it is AAA fireproof rolling shutter. Therefore, the fire resistance limit of AAA grade fireproof rolling shutter should be 3 hours.

Q:Who knows about the B-level fireproof insulation materials?: Organics, extruded sheet, polyphenyl board and phenolic resin. The fireproof?performance of sea capacity module (fireproof and thermal insulation material) is B1-level with the heat conductivity coefficient of only 0.028w / m · k. It is a good choice. A-level: Rock wool, glass wool, silicate, aluminum silicate, calcium silicate, phenolic aldehyde, and foam glass. B-level: Rubber and plastic, extrusion molding, polyphenyl, PEF.

Q:Does anyone know what is a lightweight refractory material?: Heat preservation and insulation layer used only for Thermal Equipment has poor wear resistance, loose organization and high porosity(40%~85%) . The definition of light refractory material: low thermal conductivity, good performance in thermal insulation , weak mechanical strength, low volume density(generally below 13).

Q:What brands are the best in the A-level refractory materials?: 1 International (It is a well-known brand in the field of global boats and protective coatings, the products are famous for its safety, strength and smoothness, Akzo Nobel (China) Investment Co., Ltd.) 2 LANLING (It is a high-tech enterprise, and a large provider of industrial coatings, started in 1980, as well as a famous brand of Jiangsu Province, Jiangsu Lanling Chemical Group Co., Ltd.) 3 Champion (It is a high-tech enterprise who is involved in developing a number of industry standards, it is a industry-leading brand brand of Jiangsu Province Jiangsu champion coating Technology Group Limited) 4 BBMG Coating (It is a large coating enterprise and a leading brand of fire-resistant coating who draft up the fireproof coating industry standards, Beijing BBMG Coating limited liability company) I hope my answer can help you .

Q:How many fire endurance grades are the AAA fire resisting shutter divided?: The different fire resistant levels of the building have different requirements of the fire endurance of the building component. According to the fire endurance, the fire doors can be divided into Class A, Class B and Class C fire doors with the fire resistances are not less than 1.20h, 0.90h and 0.60h. Even the fire resistant level of B can also use the first rate fire resistant door.

Q:Does anyone know which materials belong to light fire resistant material?: Fire partitions can be divided into organic and inorganic fire partitions, the main ingredient of organic fire partitions is organic material, which can be used for cable tray with corrosion-resistant and fire protection requirements, and the main ingredient of inorganic fire partitions is inorganic material, mainly used for fire protection. As the main component is inorganic material, it can not be use in projects with acid-resistant and alkali-resistant requirements. Of course, the price of the same amount of organic fire partitions is generally more expensive than that of the inorganic fire partitions . The fire endurance of these two products of general enterprises are 3 hours.

Q:What does the function of SiC for refractories?: Anti-wear! High intensity!

Q:How can refractory material of the electric furnace be used for longer.: Minimize mechanical shock, Electrical furnace commonly referred to must be electrical arc furance. The wall of electric arc furnace should be constrcuted with magnesite carbon brick. Its hearth permanent layer should be constrcuted with mansornary magnesia brick. High alumina brick is usually used to aviod furnace cover suddenly get hot and cold. But its service life is lower. At present integral casting furnace cover is made of alumina magnesia. Terminal will be created even without the use of refractory material. Consumption is much faster if using refractories material or whole knottiing mainly.
