What about low ash graphite electrode used in eaf(for smelting steel) besides high temperature resistance? 1. Low ash graphite electrode used in eaf (for smelting steel) is not only resistant to high temperature but also has good wear resistance , The smaller the coefficient of friction, the better the lubricating performance. 3. Graphite has good toughness and can become very thin flakes. 4. In addition, graphite can withstand drastic changes in temperature without being damaged when used at room temperature. When the temperature changes suddenly, the volume of graphite will not change much and no cracks will occur. In summary, the wear resistance of the low ash graphite electrode used in eaf (for smelting steel) is also very good.

EDM parameters of low ash graphite electrode used in eaf(for smelting steel)

Low ash graphite electrode used in eaf (for smelting steel) EDM parameters The selection of EDM parameters for graphite and copper materials is quite different. EDM parameters mainly include current, pulse width, pulse gap, and polarity. The following introduces the basis for the rational use of these main parameters. The current density of low ash graphite electrode used in eaf (for smelting steel) is generally 10~12 A/cm2, which is much larger than that of copper low ash graphite electrode used in eaf (for smelting steel), so the current allowed in the corresponding area In the size range, the larger the current selection, the faster the graphite electric discharge machining speed, and the lower the loss of the low ash graphite electrode used in eaf (for smelting steel), but the surface roughness will become coarser. The larger the pulse width, the lower the loss of the low ash graphite electrode used in eaf (for smelting steel). However, a larger pulse width will make the processing stability worse, and at the same time make the processing speed slower and the surface rough. In order to ensure the low loss of the low ash graphite electrode used in eaf (for smelting steel) during rough machining, a larger pulse width is usually used. When the value is between 100 and 300 us, the low ash graphite electrode used in eaf (for smelting steel) can be effectively realized. steel) low-loss processing.

In order to obtain a fine surface and stable discharge effect during finishing, a smaller pulse width should be selected. Generally, the pulse width selected for low ash graphite electrode used in eaf (for smelting steel) is about 40% less than that of copper low ash graphite electrode used in eaf (for smelting steel). The pulse gap mainly affects the EDM speed and processing stability. The larger the value, the better the processing stability. It is helpful to obtain better surface uniformity, but the processing speed will decrease. In the case of ensuring stable processing, a smaller pulse gap can be selected to obtain higher processing efficiency, but when the discharge state is unstable, a larger pulse gap can be selected to obtain higher processing efficiency. In the low ash graphite electrode used in eaf (for smelting steel), the pulse gap and pulse width are usually set at 1:1, and usually the pulse gap in copper low ash graphite electrode used in eaf (for smelting steel) And the pulse width is set by 1:3. In the case of stable graphite processing, the ratio of pulse gap to pulse width can be adjusted to 2:3. When the pulse gap is small, it is beneficial to form a covering layer on the surface of the low ash graphite electrode used in eaf (for smelting steel), which is helpful to reduce the loss of the low ash graphite electrode used in eaf (for smelting steel).

The new low ash graphite electrode used in eaf (for smelting steel) material is worthy of vigorous promotion, and its superiority will gradually be recognized and accepted by the domestic mold manufacturing industry. The correct selection of low ash graphite electrode used in eaf (for smelting steel) materials and the improvement of related process links will bring high efficiency, high quality and low cost benefits to mold manufacturing enterprises. When the Carbon Company was founded, it established the development strategy of “Technology, Innovation, and Leading”, adhering to the business philosophy of “Quality First, Service First”, after technological improvement, quality improvement, and market development, Hongsheng Carbon has become a Jin, Ji, The largest graphitization processing enterprise in Mongolia. Its main business includes low ash graphite electrode used in eaf (for smelting steel), Shijiazhuang low ash graphite electrode used in eaf (for smelting steel), and Datong silicon carbide.
