Production of silicon carbide rod in electric thermal industry
Silicon carbide (sic), also known as carborundum, is a compound of silicon and carbon with chemical formula sic. It occurs in nature as the extremely rare mineral moissanite. Silicon carbide powder has been mass-produced since 1893 for use as an abrasive. Grains of silicon carbide can be bonded together by sintering to form very hard ceramics  that are widely used in applications requiring high endurance, such as car brakes, car clutches and ceramic plates in bulletproof vests. Electronic applications of silicon carbide as light-emitting diodes (leds) and detectors in early radios were first demonstrated around 1907. Today sic is used in semiconductor electronics applications that are high-temperature, high-voltage or both. Large single crystals of silicon carbide can be grown by the lely method; they can be cut into gems known as synthetic moissanite. Silicon carbide with high surface area can be produced from sio2 contained in plant material.
Black silicon carbide use quartz sand and petroleum coke as the main raw material, smelting the raw material at high temperature electric resistance furnace . Black silicon carbide contains SiC about 95%. The toughness is higher than that of green silicon carbide, black crystals. The microhardness is HV3100-3280kg / mm², brittle and sharp and has a certain electrical conductivity and thermal conductivity. Abrasive made of black silicon carbide is suitable for grinding cast iron, nonferrous metals and rubber, leather, plastic, wood, minerals and other non-metallic materials. Additionally, you can make advanced refractory material and so on.

Stainless steel is an iron alloy with a chromium content of at least 10.5%. Chromium forms a thin oxide layer on the surface of steel, known as the passivation layer.
This can prevent further surface corrosion. Increasing the chromium content can improve corrosion resistance.
Stainless steel also contains varying amounts of carbon, silicon, and manganese.
Other elements such as nickel and molybdenum can be added to impart other useful properties, such as enhanced forming ability and increased corrosion resistance.
Waste stainless steel refers to stainless steel waste generated from industrial manufacturing and stainless steel processes, as well as stainless steel equipment that has been damaged or scrapped due to long-term use, and stainless steel utensils used in daily life. Our factory produces approximately 20 tons of stainless steel per day, and we have abundant inventory of stainless steel waste with guaranteed quality. Scrap stainless steel is a high-grade alloy steel with a higher value than ordinary scrap steel.
In its mineral form Bauxite, Aluminium is the most abundant metal in the earth's crust. Bauxite contains one of a variety of hydrated aluminium oxides (gibbsite, boehmite or diaspore), which are often expressed as Al2O3xH2O but are more commonly regarded as impure Al2O3. Bauxite is claylike and earthy, and ranges in colour from white to deep brown or red according to the nature and quantity of its components. The major impurities in Bauxite are iron oxides (goethite & hematite), silicon dioxide, the clay mineral kaolinite as well as small amounts of anatase (TiO2). Consequently, its composition varies considerably with alumina constituting from about 50% to about 70%. Aluminium content can be accurately and precisely determined over a broad analytical range simultaneously along with Si, Fe, Mn, Ti, Zr and up to 20+ other elements.
