Uses of graphite rods
1. For electric arc steelmaking furnaces:
Graphite electrodes play a critical role in electric furnace steelmaking, where current is introduced into the furnace via these electrodes. The high-intensity current generates an electric arc discharge through the gas at the lower end of the electrodes, and the heat produced by this arc is utilized for smelting processes. Depending on the capacity of the electric furnace, graphite electrodes of varying diameters are employed. To ensure continuous operation, electrodes are connected using threaded joints. Graphite electrodes used in steelmaking account for approximately 70% to 80% of total graphite electrode consumption.
2. For electric furnaces with submerged arc heating:
In this application, the lower portion of the conductive electrode is buried within the charge material. In addition to the heat generated by the electric arc between the electrode and the charge, additional heat is produced due to the electrical resistance of the charge itself when current flows through it.
3. For resistance furnaces:
Resistance furnaces are widely used in the production of graphite products, glass melting, and silicon carbide manufacturing. In these furnaces, the materials placed inside serve dual purposes: acting as both heating resistors and the objects being heated. Prior to processing, graphite rods undergo shot blasting treatment to remove impurities, thereby reducing processing intensity and enhancing efficiency.
Carbon rod outer wall shot blasting machine
The carbon rod outer wall shot blasting machine is essential equipment for manufacturers of carbon electrodes and carbon rods. It offers the following advantages:
1. The machine employs a cantilever centrifugal shot blasting system with high shot blasting capacity and rapid ejection speed, significantly improving cleaning efficiency and achieving excellent cleaning quality.
2. All design drawings for the carbon electrode outer wall shot blasting machine and the carbon rod outer wall shot blasting machine are created using computer-aided design (CAD), ensuring rational selection and layout of shot blasting equipment. Simultaneous rotation and forward movement of the carbon electrodes and rods enhance projectile utilization, increase labor productivity, ensure consistent cleaning results, and minimize wear on the chamber guard plates.
3. The cleaning chamber is protected by Mn13 guard plates, which are currently considered the most advanced protective plates for shot blasting cleaning equipment in China. These plates are cost-effective, easy to manufacture, simple to replace, and have a long service life (up to 5 years). Additionally, the separator utilizes advanced technology, greatly reducing daily maintenance costs while maintaining operational reliability.
4. Application:** Suitable for surface cleaning of cylindrical carbon rods of various diameters, meeting the shot blasting cleaning requirements of carbon rods used in steel mills.
