Product Description
Graphite Electrode Description
Advantages of graphite electrodes
1. Graphite electrode production process is simple, high efficiency, and graphite loss is small 2. Fast processing speed and low production cost 3. Different sizes are available, including large diameter 4. Our graphite electrodes are very durable and have a long service life
5. Our graphite electrodes have low resistance, high density, high oxidation resistance, high processing precision, especially low sulfur and low ash, no secondary steelmaking
Graphite electrode application
1 for electric arc furnace; 2 for submerged arc furnace; for resistance furnace; 3 for producing special-shaped graphite products; 4 for producing special-shaped graphite products.
Electrode diameter: 75-800mm. We can produce various specifications according to customer requirements. Our advantages: Manufacturer from China; Buy directly from factory; High quality products; Profitable price.
