DC hollow carbon rod hollow carbon rod Yangzhou pioneering carbide carbide for non-metallic products, as carbon arc gouging cutting process of cutting a prerequisite before welding consumables, are made of carbon, graphite combined with the appropriate adhesive , by extrusion molding, after the baking section 2200 ℃ spin coated with a layer made of copper, high temperature resistance, good electrical conductivity, not broken, is adapted to meet the requirements of the shape of the metal is cut. Since the use of high temperature and easy conductive carbon rod good chemical stability. Now widely used in national defense, machinery, metallurgy, chemical, foundry, non-ferrous alloys, light and other fields, especially black carbon rod, is also used in the field of ceramic, semiconductor, medical, environmental, laboratory analysis and other applications become the most widely used non-metallic materials. When cutting steel, no used like oxygen acetylene flame cutting flammable, explosive gas, low cost, operation safely. Arc cutting method may be processed using a variety of gas cutting processing is not a metal, such as cast iron, steel, copper, aluminum, etc., high efficiency, and are able to give more satisfactory results. The element hard and brittle texture, expansion coefficient, thermal shock resistant, not easily deformed, good chemical stability, acid ability, does not react with strong acids, alkali poor ability to decompose at high temperature corrosion stick body. Flexural strength of the carbon rod, with the device temperature rises and becomes greater the hardness. Resistance element via a resistor straightforward reflection is based on ministerial standards prescribed in 25 micro ohm meter measurements. Element surface load current density and black carbon rod density formula of raw materials and pressed closely, can be adjusted as needed. Round carbide: gouging is mainly used for the weld, and remove the back slotted welding defects; rectangular carbon rod: the member for eliminating the residual temporary weld and weld scars, remove weld reinforcement and carbon arc cutting; connection-shaped carbon rod: suitable for automatic or manual type gun, continuous feed, you can reduce the loss of the use of the residual carbon rod, gouging high precision, smooth and uniform, good stability and high efficiency. 1, the carbon rod must be kept dry, damp subject to drying before using. 2, for the DC power supply carbide positive power supply, work then negative. 3, the air pressure to keep 0.5-1.6MPa. 4, the arc distance between the carbon rod and the workpiece about 3mm, carbon rods exposed jig about 100mm. 5, the carbon rod into a 45 ° angle with the workpiece, and the tangential (or line) direction of the planing. 6, must be well ventilated when using carbon rod. Press the operating current operations.
