 Black Silicon Carbide is made by a precision water classification process and air flow classification using material that is produced from the reaction between high purity silica sand and petroleum coke in a resistance-type furnace. Measuring 9.0+ on the MOHS scale of hardness, silicon carbide is one of the hardest abrasives known in the industry. The inherent friability of the sharp crystalline structure assures the continuous exposure of new cutting edges, which produces a faster and cleaner cutting performance.

 

Green silicon carbide is produced as the same type as the black silicon carbide,except the different raw materials. It’s crystallization have higher purity and hardness.Green silicon carbide is suitable for processing hard alloy,metallic 

and non-metallic material with hard and brittle feature such as copper, brass, aluminum,magnesium,jewel, optical glass, ceramics, etc. Super micro-power of it is also a kind of ceramics material.

Q:How many fire endurance grades are the AAA fire resisting shutter divided?
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:What needs to be paid attention to in the construction of high- temperature refractory mortar?
As far as I'm concerned, in the construction of high-temperature refractory mortar, these matters should be noted: 1. During the use of high-temperature daub masonry stove, the minimum mortar joint should be 0.5mm and general mortar joint should be 3-5mm, which can solve the processing and fine grinding of refractory brick on the brick grinder. Besides, it is conducive to the health of workers, and can reduce the masonry effort, ensure the quality and speed up the construction progress. 2. When making urgent repair on the stove, if the joint is much too large, 2-3mm refractory pieces can be appropriately added into the high- temperature refractory mortar, and stirred to fill the joint so as to shorten the repair time and ensure normal production. 3. High- temperature refractory mortar can be painted inside various furnace body, and it should be guaranteed that the surface of the furnace body has no dust or debris before painting.
Q:What are the refractories for converter?
Analysis of refractories are as follows: MgO-C brick converter Dongxin refractory furnace cap, steel tapping hole, shaft, shaft, pool, air brick
Q:How should fireproof building materials be ranked?
According to our national standard GB8624-97, the combustion performance of building materials are divided into the following levels: A class: Incombustible building materials: the material is almost incombustible. B1 class: Flame-retardant building materials: they are better in fire retardation. It is non-combustible when meeting open fire in the air or under high temperature, and it is difficult for the fire to spread quickly. Besides, when the fire source is removed, combustion stops immediately. B2 class: Combustible building material: It has certain fire retardation. In case of open fire in the air or at high temperature, it will immediately burst into flames, and easily lead to the spread of fire, such as the spread to wooden pillars, timber roof truss, timber beams, wood stairs, etc. B3 class: Flammable building material: It has no fire retardant effect at all, but is highly flammable with high fire risk. Hope my answer can be accepted.
Q:which kind of refractory is commonly used in the industry
Therefore it is known as special fire-resistant materials, such as yttria, high alumina raw material (sometimes neutral), olivine,which is used for alkalinity furnace, dolomite, and we roughly divided into several categories, beryllia, cerium oxide, these materials have a strong alkaline slag resistance, thorium oxide, lime, serpentine, which is picked from these refractory raw materials. the raw materials of basic refractory materials are mainly magnesia clay and titanium oxide, but because not many sources of raw materials, it can not be widely applied in the refractory industry, and we can analyze which kind of materal is processed by the pulverizer. There are many kinds of refractory materials, rotary kiln can only be used in particular circumstances. These materials have a variety of slag resistance at different degrees. the main material of special refractories is zirconium oxide. the refractory clay is the most basic and most widely used raw material in the refractory industry.
Q:How to make the service life of refractory materials longer?
Take acid resistant refractory materials as example: the atmosphere should be acidic atmosphere, if used in an environment whose temperature is 1900℃, it would exacerbate the loss of refractory materials, so don’t use overloaded. Second, select the appropriate refractory materials according to the environment. For example, if its operating temperature is 1800℃, generally speaking, the normal use of it according to the instruction of refractory materials would be fine.
Q:Does anyone know the refractory temperature of fire-resistant glass?
Ordinary glass will be completely liquefied in the furnace of about 1100 degrees for half an hour and will not deform below 600 degrees. toughened glass fire-resistant glass is the product of ordinary glass after being processed Glass will mainly burst after encountering fire. When unevenly heated or encountering sudden drastic changes in temperature, ordinary glass will burst if the sharp temperature difference is over 70-120 degrees and toughened glass will burst at 200 degrees. It is not yet clear of the bursting temperature for the refractory glass. If the overall glass is not heated evenly, it will have no significant change below 600 degrees, and it will deform with the increase of temperature until melting. The fire-resistant time of the glass you said is the time to heat the glass into the extreme temperature differences it can endure, which should not be more than 10 minutes
Q:How to distinguish the construction fire-proof material rating?
Currently the national standards divide building materials as follows: A1, A2, B, C, D, E, F. External wall thermal insulation fire rating can be basically divided into: A1, A2, B1, B2, B3 and other levels. Class A is non-combustible, class B1 flame retardant, class B2 combustible, class B3 flammable. Combustion performance grades of building materials and products are divided into class A1, A2, B, C, D, E, F. And grading of flooring materials and pipeline thermal insulation materials is also stipulated separately, whose combustion performance grade is distinguished by the subscript fl and L respectively. ie. Combustion performance grades for ordinary building materials and products are A1, A2, B, C, D, E, F; combustion performance grades for paving material are Alfl, A2fl, Bfl, Cfl, Dfl, Efl, Ffl; combustion performance grades for pipeline thermal insulation material are A1L, A2L, BL, CL, DL, EL, FL.
Q:how is the high-temperature flame-retardant fibre board?
Still good, we still can understand, we still feel good, I still can understand the amount of
Q:What is the magnesium carbon refractory?
The composition of refractory brick raw material There are many types of refractory brick raw materials, mainly divided into six categories: Soil, stone, sand, mineral, power and others. One of the original material, soil: Aluminum, kaolin, clay, diatomaceous earth The second raw material, Stone: fluorite, kyanite, andalusite, forsterite, vermiculite, mullite, pyrophyllite, chlorite, dolomite, sillimanite, magnesia-alumina spinel, silica The third kind of raw material, sand: Pottery, zircon sand, quartz sand, magnesite The fourth kind of raw material, ore: Chrome ore The fifth kind of raw material, powder: Aluminum powder, silica powder, silicon powder The sixth kind of raw material of refractory brick, others: Asphalt, graphite, phenolic resins, perlite, cenosphere, sialon, corundum, silicon sulfate, silicon carbide, sodium silicate, silica solution, boron carbide, calcium aluminate cement, nitride material, shale ceramisite, alumina, alumina sol and zirconia, etc.
