Shaanxi graphite carbon rod graphite carbon rod uses

Henan Henan graphite carbon rod graphite carbon rod factory price graphite rod commonly used in high-temperature vacuum furnace electric body, the maximum temperature up to 3000 ℃, susceptible to oxidation at high temperatures, in addition to the vacuum, but only in a neutral atmosphere or reducing atmosphere use. Its thermal expansion coefficient is small, a large thermal conductivity, a resistivity of (8 ~ 13) × 10-6 Ω · m, the workability than SiC, MoSi2 rods, high temperature resistance, extreme cold or heat is good, the price cheaper. Graphite rod for non-metallic products, carbon arc gouging cutting process as a necessary pre-cut welding consumables, are made of carbon, graphite combined with a suitable adhesive, by extrusion, by 2200 ℃ baking spin rear section made of copper plated layer, high temperature, good electrical conductivity, not broken, cut into a suitable shape to meet the requirements of the metal. Uses: As the use of high temperature carbide easy conductivity good chemical stability. Now widely used in national defense, machinery, metallurgy, chemical, foundry, non-ferrous alloys, light and other fields, especially black carbon rod, also used as a field of ceramics, semiconductor, medical, environmental, laboratory analysis and other applications become the most widely used non-metallic materials. When cutting steel, not like the oxygen - acetylene flame cutting as the use of flammable, explosive gas, low cost, operation safety. Arc cutting method can not be processed by gas cutting processing of a variety of metals, such as cast iron, stainless steel, copper, aluminum, etc., high efficiency, and can obtain more satisfactory results. Performance: This component hard and brittle texture, expansion coefficient, thermal shock resistant, not easily deformed, good chemical stability, acid ability, does not react with strong acids, alkali resistance is poor, at high temperature corrosion Decomposition rods. Flexural strength carbon rod, with the device temperature rises becomes greater the hardness. Resistance element via a resistor straightforward reflection is based on ministerial standards prescribed in 25 micro ohm-meter measurement. Element surface load current density and black carbon rod density formula of raw materials and pressed closely, can be adjusted as needed. Carbide classification: 1, round carbide: mainly used for gouging weld, welding defects on the back of the slot and clear; 2, rectangular carbon rod: the member for eliminating the residual temporary weld and welding scars, clear carbon arc weld reinforcement and cutting; 3, carbon rod-shaped connection: Suitable for automatic or manual type torch, continuous feed, you can reduce the loss of the use of the residual carbon rod, high precision planing, smooth uniform, stability Well, high efficiency. Carbide for use: 1, carbide must be kept dry, damp subject to drying before using. 2, for the DC power supply connected to the positive supply carbon rod, then negative work. 3, the air pressure to keep 0.5-1.6MPa. 4, the arc distance between the carbon rod and the workpiece about 3mm, carbide expose fixture about 100mm. 5, carbon rod angle of 45 ° with the workpiece, and tangential (or line) direction planing. 6, must be well ventilated when using carbide. Press the operating current operation. Gongyi City, Henan Ruifeng graphite products company /// Henan graphite carbon rod graphite carbon rod factory price
