Graphite Rod with Dia. 50mm/75mm/140mm

Advantages of graphite rod

1.Graphite rod used in high temperature vacuum furnace heating body, the highest temperature can reach 3000 ℃, is easy to be oxidized at high temperature, in addition to vacuum, can only be used in the neutral atmosphere and reducing atmosphere 2.Its small thermal expansion coefficient, thermal conductivity, resistance coefficient is (8 ~ 13) 2 x 10-6 M, work ability is SIC, MOS12 bar is good, high temperature resistance .The extremely cold heat resistance is good, price is declared 3.Because of the characteristics of graphite rod has the nature of high temperature resistant, so we can often see it in the metallurgical industry, it can be used to make into a graphite crucible, so when it is used in steel can be referred to as protectant , resistance is the remedy for gold. 4.When the production of chemical products can be used to fire graphite rod, because it can produce volume under the condition of heat, and then swelling and suffocation flame, so have the effect of isolation from the flame, to guarantee safety in chemical products in the production process.

The use of graphite rod

Due to the carbon rods use high temperature easy conductive good chemical stability. Has been widely used in national defense, machinery, metallurgy, chemical, casting, non-ferrous metal, light, and other fields, the nine is black carbon rod, is also used as ceramic, semiconductor, medical, environmental protection, laboratory analysis and other fields, become the most widely used non-metallic materials today. When cutting steel, do not need to use like oxygen - acetylene flame cutting is flammable, explosive gas, low cost and operation safety. Can use the method of arc cutting processing a variety of can not use gas cutting processing of metal, such as cast iron, stainless steel, copper, aluminum, high efficiency, and can get ideal effect. Carbon rods can also be used for aluminum hot metal mixing water, oxidation resistance, corrosion resistance.
