Uses:
Due to the Carbon gouging rods get good chemical stability of high temperature and easy conduct . 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, become the most widely used non-metallic materials today . When cutting steel, does not require that the use of oxygen- acetylene flame cutting as flammable, explosive gas , low cost , operation safety. Arc cutting method can not be processed by gas cutting processing various metals , such as iron , stainless steel, copper, aluminum , high efficiency, and can obtain a more desirable effect.
Performance:
The device hard and brittle texture , expansion coefficient, thermal shock capability , easily deformed , good chemical stability, acid resistance strong , 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 rise of temperature of the element becomes larger hardness. The resistance of components , through a resistor outspoken reflected by the ministerial standards are defined in 25 micro- ohms. Meters measured . Element surface load current density and black carbon rod density formula of raw materials and pressed closely , can be adjusted according to need .
