Description¡gthe electrodes carry the electricity that heats electric arc furnaces, the vast majority steel furnaces. They are made from petroleum coke after it is mixed with petroleum pitch, extruded and shaped, then baked to sinter it, and then graphitized by heating it above the temperature (3000xc) that converts carbon to graphite. They can vary in size up to 11 ft. Long and 30 in. In diameter.Usage: an increasing proportion of global steel is made using electric arc furnaces, and the electric arc furnace itself is getting more efficient and making more steel per tonne of electrode 35 kgs paper bag

Wealson offers carbon and graphite felts in a variety of widths and thicknesses to meet a wide range of applications. These products are easy to cut and install. The felts can be sewn in place using carbon cordage. Felt material is generally used as thermal insulation in inert and vacuum furnaces. For special applications, this felt is available with graphite coatings which will reduce the permeability of the felt and improve its resistance to erosion. Wealson's felt can be surface coated with graphite foil bonded or combined with carbon/carbon face plates to provide an insulation system that is utilized with operations such as rapid gas quenching, resulting in longer useful life of the insulation system. Additionally, Wealson's carbon and graphite felt is available in a rigid form that can be manufactured into various shapes, including: Baffle, Cylinder, Ring and Board.
A crucible is a container used to hold metal for melting in a furnace and it is needed to withstand the extreme temperatures encountered in melting metals. The crucible material must have a much higher melting point than that of the metal being melted and it must have good strength even when white hot. Graphite crucible can withstand the high temperature, and has good resistance to chemical erosions and thermal shock. Especially graphite crucible is ideal for the melting of aluminum, copper and other metals. Quartz crucible has the advantages of high purity ,high temperature resistance, with big size ,good thermal insulation, economization on energy ,quality stability etc. Fused quartz crucibles are used in the manufacture of silicon metal for semiconductor wafer applications and polysilicon. In order to produce high quality wafers, starting materials are added to a crucible heated to high temperatures and pulled from the melt as a single crystal. Fused Quartz is one of the few materials that can combine the high purity and high temperature properties required for this process. GW offers graphite crucibles & Ceramics (Quartz) crucibles in different sizes and types. Whenever you need crucibles, just feel free to contact us, and we will reply you in a shortest time.

Pure graphite is a mineral form of the element carbon (atomic number 6) and its symbol is c. It forms in veins in metamorphic rocks as the result of the metamorphism of organic material included in limestone deposits. It is an extremely soft mineral at 1 to 2 on mohs' hardness scale. It is black and has a black streak. (streak is the color of a mineral when it is crushed to a powder). Its softness and streak make graphite useful in making f+leadf+ for pencils. Crystals are uncommon, but when they occur, they are found as rough, six-sided (hexagonal) flakes. It breaks into minute, flexible flakes that easily slide over one another. Mineralogists call this basal cleavage. This feature is the cause of graphite distinctive greasy feel. It is this greasy characteristic that makes graphite a good lubricant. Because it is a solid material, it is known as a dry lubricant. Graphite is the only non-metal element that is a good conductor of electricity. 25kg/bag;1 ton.Kraft bag.20ton/20fcl.

Natural graphite is used mostly in what are called refractory applications. Refractory applications are those that involve extremely high heat and therefore demand materials that will not melt or disintegrate under such extreme conditions. One example of this use is in the crucibles used in the steel industry. Such refractory applications account for the majority of the usage of graphite. It is also used to make brake linings, lubricants, and molds in foundries. A variety of other industrial uses account for the remaining graphite consumed each year. 25kg/bag;1 ton/ kraft bag;20 ton/20fcl or ad the customer request.
