Graphite Electrode Selection
Graphite electrode oxidation is one of the significant factors affecting electrode consumption during EAF steelmaking. When oxidation occurs, the electrode loses its structural integrity, leading to rusting and flaking.
The sublimation and dissolution of graphite electrodes can also lead to considerable consumption rates during EAF steelmaking.
Spalling and breaking of graphite electrodes are also significant consumption factors during EAF steelmaking.
The diameter and length of the graphite electrode are also crucial factors to consider when choosing electrodes for EAF steelmaking.
Graphite Electrode Maintenance
Once you have chosen the right graphite electrode, it's essential to maintain it properly to minimize electrode consumption. Regular inspections and cleaning are necessary to remove any debris or slag buildup on the electrodes, which can increase resistance and reduce efficiency. Additionally, the proper storage of electrodes is vital to maintain their quality. Storage areas must be dry, well-ventilated, and free from contaminating elements such as oil or moisture. It's also essential to handle the electrodes with care to prevent damage during transportation and installation.Proper use and maintenance can effectively reduce graphite electrode consumption.
We are the manufacture owned complete production line and professional team.
For every production processing,we have complete QC system for the chemical composition and Physical properties.After production,all the goods will be tested.We will use the gauge imported from Japan with high-precision measurement between nipple and electrode. We also will inspect other specifications such as resistance, bulk density etc. will be checked and tested by the professional equipment before delivery from our manufacture.
Currently, Gufan mainly produces high quality graphite electrodes including UHP,HP,RP grade,from diameter 200mm(8”) to 700mm(28”).which are capable for using in Electric Arc Furnace. The large diameters, such as UHP700,UHP650 and UHP600, get good feedback from our customers.
