Sizes of Carbon Arc Air Gouging Rods
Application of Carbon Arc Air Gouging Carbon Rod
Due to the high operating temperature of carbon rods, good electrical conductivity, and excellent chemical stability, they are now widely used in various fields such as national defense, machinery, metallurgy, chemical engineering, casting, non-ferrous metals, and light industries. In particular, black carbon rods are also used in ceramics, semiconductors, medicine, environmental protection, laboratory analysis, and other fields, making them the most widely used non-metallic materials today. When cutting steel, there is no need to use flammable and explosive gases like in the oxygen-acetylene flame cutting process, making it cost-effective and safe to operate. The electric arc cutting method can process various metals that cannot be processed by gas cutting, such as cast iron, stainless steel, copper, aluminum, etc., with high efficiency and ideal results.Carbon Arc Air Gouging Carbon Rod Performance
This element has a hard and brittle texture, a low coefficient of expansion, and can withstand rapid cooling and heating without deformation. It has good chemical stability, extremely strong acid resistance, and does not react with strong acids. However, it has poor alkali resistance and can decompose at high temperatures.
The flexural strength of the carbon rod increases with the increase in element temperature. The resistance value of the element, which is truly reflected by its resistivity, is measured according to the standard specified by the department, at 25 micro-ohms per meter.
The surface current density of the element is closely related to the formula of the black carbon rod material and the compaction density, which can be adjusted as needed.
