Carbon rods are made of carbon, graphite, and other substances plus adhesives, which are highly conductive and difficult to break.
Carbon rods are made of carbon and graphite with an appropriate adhesive, extruded, baked at 2200℃, and coated with copper, which are high-temperature resistant, good conductivity, not easy to break, and suitable for cutting the metal into required shapes. Today carbon rods supplier will take you to understand carbon rods.
It is hard and brittle, has small expansion coefficient, can withstand rapid cold and heat, is not easy to deform, has good chemical stability, has strong acid resistance, does not react with strong acid, has poor alkali resistance, and can be decomposed by corrosion at high temperature.
The bending strength of carbon rods becomes harder as the temperature of the element rises. The resistance value of the element, as reflected by the resistivity, is measured at 25 micro-ohms, as specified by the ministerial standard. The resistance of the element, as reflected by its resistivity, is measured at 25 µm.
The surface load current density of the component is closely related to the raw material formulation and pressing density of the black carbon rods, which can be adjusted arbitrarily according to the needs.
Round carbon rods: mainly used for root cleaning, backside grooving and removal of welding defects; rectangular carbon rods: used for shaving off the residual temporary weld path and weld scar on the components, removing the residual height of the weld and carbon arc cutting; connected carbon rods: suitable for automatic or manual torches, continuous feed, which can reduce the loss of residual carbon rods during use, high precision, smooth and even grooving, good stability and high efficiency.

It has been widely used in national defense, machinery, metallurgy, chemical industry, foundry, non-ferrous alloy, light chemical and other fields, especially black carbon rods, but also used as ceramics, semiconductor, medical, environmental protection, laboratory analysis and other fields, has become the most widely used non-metallic materials.
When cutting steel, there is no need to use flammable and explosive gases like oxy-acetylene flame cutting, low cost, safe operation and use. The arc cutting method can be used to process a variety of metals that can not be processed by gas cutting, such as cast iron, stainless steel, copper, aluminum, etc., high efficiency, and can be more ideal results.
1.The carbon rods must be kept dry and can only be used after drying when wet.
2.When it is used in DC power supply, the carbon rod is connected to the positive pole of power supply and the work is connected to the negative pole.
3.The compressed air pressure is 0.5-1.6MPa.
The arc distance between the carbon rod and the workpiece is about 3mm, and the carbon rod is about 100mm from the clamp.
5.The carbon bar and the workpiece make an angle of 45°, and planing along the tangent (or straight line) direction.
6.The carbon rods must be well ventilated when using. Operate according to the working current.
