 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:What requirements should refractory materials meet?
Ladle is an necessary equipment to undertake molten steel and continuous casting. As many kinds of steel needs to be processed in the ladle, including argon blowing tempering, alloy composition fine-tuning, refining dusting and vacuum processing, working conditions of the ladle lining have worsened. Their working conditions are as follows. (1) The temperature of molten steel is higher than mold casting ladle. (2) the molten steel stays longerin the ladle. (3) ladle lining are subjected to volatilization and agitation of molten steel under high temperatures and in vacuum. (4) The impact on the lining when undertaking steel liner when the impact effect. Therefore requirements of the ladle refractories are as follows: (1) It can resist high temperature. Molten steel should be able to withstand high temperatures without melting. (2) It can resist thermal shock and can withstand molten steel without cracking and spalling. (3) It can resist slag erosion. The ladle should be able to withstand the erosion of lining caused by slag and alkalinity changes of slag. (4) it should have sufficiently high temperature mechanical strength to withstand the agitation and scouring of molten steel. (5) lined should have certain swelling property so that lining will be united as a whole under the effect of hyperthermal molten steel.
Q:What are the requirements for the performance of refractory materials?
Performance requirements for electric furnace lining refractory: 1, sufficient refractoriness and softening point. Because of eletric arc, the inner surface temperature of lining can be as high as 1500 to 1800 degree. 2, strong resistance to slag. Because the dust penetrate into the furnace through pore lining, and the refractory material subject to loss, leading to spalling. 3, good thermal and shock resistance. Because during steelmaking, opening door and lifting of the furnace will lead to sudden changes in the temperature of the furnace lining refractory material, so spalling and cracking may occur, damaging the lining premature. 4, enough strength, because the lining is impact during charging, tilted when vibration,and eroded by metal, slag and airflow. 5, the thermal conductivity shall be small, and the conductivity shall be low. The commonly used furnace refractories are dolomite brick, magnesia brick, high alumina brick, silica brick and magnesia ramming etc.. Because of different working conditions of the various parts of the furnace, the refractory materials are not the same.
Q:What kind of refractory materials are used in the intermediate frequency furnace?The domestic boric acid can be used as a lining?, how much is the rate?
Acid, neutral, basic and composite materials are used in intermediate frequency furnace. Boric acid is used according to the type of steel, the specific ratio is too generalized, and it shall be determined when the type of steel is detailed.
Q:What are the main components of refractory cement?
Refractory cement, also known as aluminate cement, can also be gray. Aluminate cement is often yellow or brown. Aluminate cement takes bauxite and limestone as raw materials, alumina content of about 50% as the clinker. And it is a hydraulic cementing material made by grinding. The main mineral of aluminate cement is mono calcium aluminate (CaO · Al2O3, abbreviated CA) and other aluminates, and a small amount of dicalcium silicate (2CaO · SiO2), etc.
Q:What defect does fused cast refractories have ?
The impact on the quality of glass is mainly the defects that eroded down refractory materials mixed in the glass, thus being prodeced of grass products. Defects are mainly foreign body defects such as sand, knot and wave reinforcement.
Q:How to count the construction costs of refractories?
In winter, the temperature of the the fire-resistant masonry, fire-resistant plastic, sodium silicate, phosphoric acid castable should be maintained above 5 ℃. Usually greenhouses in which heating facilities are installed to maintain the appropriate temperaturere for the construction environment should be erected in refractory masonry. The temperature around the construction site of the industrial furnace and refractory masonry shall not be lower than 5 ℃.
Q:What is the criterion of entry of refractory clay industry?
Refractory clay refers to clay which has a refractoriness of more than 1580 ℃ and can be used as refractory material and bauxite which used as refractory material . In addition to a higher refractoriness, they can keep the stability of volume under high temperature conditions and have slag resistance and thermal shock resistance and mechanical strength, so they are extremely firm after calcination.
Q:Kinds of refractory mortar
It needs no heating when hardened. There are two kinds of refractory mortar, the finished products and semi-finished products. Clinker is compounded in proportion according to the hardening temperature. (3) Chemical bonding refractory mortar is made from refractory aggregate and chemical binders (inorganic, high alumina refractory mortar). After this refractory mortar with thermal hardness is hardened, it has some contraction. Ther is a wide variety of refractories used on the constrcuction sites: // a, Advanced refractories (1770 ~ 2000 ℃) and AAA level refractories (2000 ℃ above). It can only be delivered in dry state. Air hardening refractory mortar is often compounded air hardening binders such as sodium silicate. It will harden below ceramic bonding temperature. According to different binding agents.
Q:Why does refractory need to add coarse firstly and then add fine aggregate?
Binding agent can wrap particles and improve binding effect.
Q:Fire insulation and fireproof insulation board materials What is the difference in performance?
Fireproof Materials prevents burning through insulating while others by chemical reactions. The overall heat conductivity coefficient of Insulation materials are generally lowered by thermal conductivity of the material itself and the structure of it. Inorganic active insulation material uses ordinary cement, insulation stone, calcium powder, Platycodon grandiflorum as the main raw material.
