Q:How many types do refractory bricks have? Where the quality of refractory material is best? What is the model?: Sinosteel Luoyang (Luoyang Refractory Material Plant in the past): High alumina(mainly blast furnace), Gongyi. There are also a series of high-tech materials (silicon carbide, carborundum, etc.) a major producer of high alumina; silicious: Resistant material for steel, glass furnace, cement kiln); magnesia. Divide from uses and divide from chemical texture; silicious(glass furnace): Xinmi, Hennan Province, Lengshui River, coke oven, etc.). As for the models, Yixing and Changxing in Jiangsu Province: Haicheng, Liaoning Province; silicious, I do not understand your intentions; magnesia (nonferrous, steel refining; magnesia: High alumina brick; Dashiqiao area! Please put it in detail.

Q:Does the aluminum silicate thermal insulation material fireproof?: With stable performance,long fiber length, strong tensile strength, strong seismic performance, low shot, light unit weight, low thermal conductivity, good insulation properties. it is not bad.

Q:Who knows the external wall thermal insulation materials fire rating requirements?: The requirements of Department of Housing and the Ministry of Public Security No. 46: Residential buildings: the height of building is greater than 100 meters, the combustion performance of insulation materials should be level A. The other civil buildings: 24≤ height

Q:how to use boiler fireclay: Boiler refractory, diluted with water to touch the places where needed, can be used after high temperature baking.

Q:What kind of material is good for cabinet fireproof board: What kind of material is good for cabinet fireproof board What are the advantages and disadvantages of using it? How much is the price? A about how much does one piece cost?

Q:Can I use ordinary cement with the addition of sand, clay, and salt as refractory material to paste the stove?: You can add some hair, sand, yellow mud and some salt, but don’t use cement, it would lead to a thermal explosion.

Q:What is required to do refractory material?: Can you be more specific about what aspect?

Q:I want to consult the fire resistant level standards of external wall thermal insulation materials.: 1, The thermal insulation material that has level A combustion performance: Spraying inorganic fiber, glass wool, foam glass, ceramic foam, rock wool, foam cement and perlite obturator, and so on. 2, The thermal insulation material that has level B1 combustion performance: Special processed extruded polystyrene board (XPS) / special processed polyurethane (PU), phenolic and polystyrene powder. 3, Thermal insulation materials that have level B2 combustion performance: Molded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU), polyethylene (PE), etc. See article 4.3.6 in the 2009 edition construction technical measures. Level A insulation material is just for fire protection, so its thermal insulation performance is worse than the organic XPS or EPS materials. Hope this will help you.

Q:Who knows what is the standard of insulation material whose fire proof is level A?: Non combustible materials of level A: WW inorganic active wall thermal insulation material, Cement foaming thermal insulation board, Glazed hollow bead insulation mortar, rock wool board, Glass wool board, Foam ceramic.Non combustible materials of level A, endowed with low density, low thermal conductivity, higher bearing capacity, convenient construction , economy and durability, are widely used in heat pipe, heat equipment, other industrial pipeline equipment , thermal insulating materials on industrial buildings, and used as heat preservation, thermal insulation, sound absorption materials of industrial and civic buildings.Non combustible materials of level A are used more for refractory protection coating material of steel structure because of its good thermal stability.

Q:What kind of material is refractory bauxite?: Bauxite (aluminous soil; bauxite), also known as alumina or bauxite ore whose main component is alumina oxde, is a hydrated alumina containing impurities. It is an earthy mineral. It is white or gray, and as it contains iron, it is also brownish yellow or light red. Density of 2.4-2.5g / cm3, hardness 1-3, opaque and crispy. It is extremely difficult to melt.
