For non metal products as carbon, carbon arc gouging cutting process is an essential pre welding cutting supplies, is composed of carbon and graphite with appropriate adhesive, through the extrusion, the temperature of 2200 DEG C after baking rotary plating a layer made from copper, high temperature resistance, good electrical conductivity, not easy to break that is suitable for metal cutting into required shape.
purpose
The chemical stability of carbon using high temperature conductive good. It has been widely used in machinery, metallurgy, national defense, chemical, foundry, non-ferrous alloy, light and other fields, especially black carbon is also used as the field of ceramics, semiconductors, medicine, environmental protection, laboratory analysis, become non metallic materials widely used. When cutting steel, it is not necessary to use flammable and explosive gas, such as oxygen acetylene flame cutting. You can use the method of processing a variety of arc cutting can not use gas cutting processing of metals, such as iron, stainless steel, copper, aluminum, high efficiency, and can obtain the ideal effect.
performance
The element is hard and brittle, the coefficient of expansion is small, the ability to quench the heat, not easy to deformation, good chemical stability, acid fast ability, and strong acid does not react, alkali resistance is poor, at high temperature can be decomposed.
The flexural strength of carbon, with the increase of temperature and hardness of the element becomes large. The resistance value of the element is reflected by the resistance, which is determined by the standard of the Ministry in 25 micro ohm meter.
The raw material formula of surface load current density and carbon black elements are closely related and pressed density, can be arbitrarily adjusted.
Element classification
Round rod: mainly used for weld root cleaning, cleaning and back notch welding defect;
Rectangular carbon: for temporary weld residual eliminating member and welding scar, remove excess weld metal and carbon arc cutting;
Connection: carbon is suitable for automatic or manual welding gun, continuous feed, can reduce the loss of residual carbon use, gouging high precision, smooth, good stability, high efficiency.
Instructions
1, carbon must be kept dry, moisture is subject to drying can be used.
2, for the DC power supply is connected to the power supply is connected to the anode cathode work.
3, compressed air pressure to maintain 0.5-1.6MPa.
4, the carbon electrode and workpiece arc distance of about 3mm, is exposed fixture is about 100mm.
5, the carbon electrode and workpiece at a 45 degree angle, and along the tangent direction of plane (or line).
6, carbon use must be well ventilated. Operating current.
