Product Description
Bauxite Material sand brown fused alumina
1. Specifications
1).High purity and good sutability. 2).Corrosion resistance and high hardness.
3).Controlled quality and Stable supply 4).Timely delivery
2. Description
China Black Silicon Carbide Abrasive for Refractory features high hardness(HV=3100-3300kg/mm2), is brittle and has a sharp nature and maintain certain electrical conductivity and thermal
conductivity and thermal conductivity.
P Series: P16-P2500, 27 Grit Numbers
F Series: P14-P1200, 30 Grit Numbers
3.Advantages
1). Corrosion resistance, high strength, high hardness.
2). Good wear-resisting performance,resist to shock.
3). It is a cost-effective substitute for Ferrosilicon.
4).It costs less than ferrosilicon and carbon combination.
5). It has no dust nuisance while feeding the material.
4. Applications
The abrasive tools made from China Black Silicon Carbide Abrasive for Refractory is applicable to non-ferrous materials with tensile strength, such as nonferrous metals, wood, leather, plastic, rubber, stone material, gray
cast iron, silicate material (glass, ceramic, concrete and refractory matter), etc. Adding a proper amount of black
silicon carbide as deoxidant during the smelting of steels can significantly improve the quality of steels. Due to its heat resistance, resistance to chemical attack and thermal shock resistance, it is widely used in high quality
refractory matter and other industries.
- Q: What are unshaped fire-resisitance materials?
- Refractory castable, refractory plastic material, usually classified according to construction and manufacture method, unfired bricks precast block, refractory pressed into material, refractory cast material, refractory coating, refractory ramming material there are many classification methods
- Q: Urgently!! Refractory problems, online, etc.
- Uneven contraction. When the magnesia block wall is made, the steel wire mesh can be added to the magnesium block wall. That will solve the problem.
- Q: Which industry does refractory belong to?
- It belongs to inorganic refractory: Ceramic refractory bricks (used in steel-making furnaces) There is also organic polymer in heavy industry: Halogen-containing and halogen-free It belongs to construction industry.
- Q: How long is the fire endurance of Grade A fire resisting shutter
- The fire endurance of Grade A fire resisting shutter is not lower than 1.20h. Use fire resisting shutter as fire?compartment separation in places where it is difficult to set firewall. When fire resisting shutter whose unexposed surface temperature rise is used as judging condition of fire endurance is used, its fire endurance should not be lower than 3h. When fire resisting shutter whose unexposed surface temperature rise is used as judging condition of fire endurance is not used, individual protection of ?closed automatic water spray system shoule be set at two sides of the shutters and duration of water spray system should not be less than 3.0h.
- Q: How to choose thermal insulation materials for flood heating?
- By controlling the foaming ratio, nucleating agent size, moudle pressure, temperature of screw, vacuum foaming technology, extruded sheet of different density can be made. The density of commonly used plastic extruded board is 25-50 kg per cubic meter. Plate density is the main factor affecting the cost of the extruded plate. The higher the plate density, the higher the cost price. Plate density is the main factor affecting the cost of the extruded plate. The lower the density of extruded board, the worse quality performance. Plate density of common plastic extruded is between 30 to 38 kilograms per cubic meter. The density of plastic extruded plate of exterior wall is between 30-35, if the density is too low, then the plate will not be strong enough, if high, flexibility of plastic extruded board will be inadequent, unable to bear the stress brought by housing settlement deformation, resulting in cracks in the wall. With the extrusion plate for floor heating should be in 36 kilograms per cubic meter. If it is too low, ground subsidence will occur due to the low strength, resulting in the ground crack. If density is too high, the thermal conductivity coefficient will increases, impacting energy saving. High density extruded plate is generally used for occasions having special requirements for compressive. Parking lot roof should use extruded plate above X350, whose density is 40 kg per cubic meter. The aircraft need to use the Ping extruded board above X500, density in 45 kilograms per cubic meters. High speed railway subgrade need to use extruded plastic board above 700KPA,
- Q: What is the material composition of the new fire-resistant coating?
- New fire?retardant?coating materials are produced by non-toxic expanding materials and special process, with no pollution. Use natural bite when installing, without using the formaldehyde and other toxic glue. It consists of a variety of organic matters, so it adapts to the natural environment, with long time of fire-resistant; The fire-resistant time for new fire retardant module is up to 4 hours or more, three hours more than the standard prescribed by the state. It is composed by the specially formulated materials, with no flying smoke, good heat insulation effect, fast heat dissipation, scientific and rational design, easy using and no falling off and long period of effective.
- Q: What high-molecular polymers can be used as fire-resistant material binder?
- Melamine resin should be compounded with fire-resistant material and acrylic acid material is easy to burn. But high-molecular polymers can be used along with the above two. Polysulfone is featured by heat resistance and high temperature resistance. Polyurethane is difficult to process and compound with fire-resistant material. Phenolic resin is not easy to burn. Epoxy is expensive and self-extinguishing once away from fire.
- Q: Can refractory be used as sealing element?
- It can. For example, a kind of irregular part that is made of fiber or some injection mix is used for sealing things.
- Q: How many kilns using refractories are needed? What are the furnaces respectively?
- There are many magnesia-chrome bricks and alkali insulation tiles); aluminum manufacturer roaster; The bottom of the glassworks regenerative chamber generally use the clay checker bricks, which is popularly used in many places of the steel mill. the upper of the power plant uses low pore brick and magnesia bricks. The forehearth uses the corundum bricks, and the cement plant uses dry and wet rotary?kiln (silmo brick
