graphite electrode paste supplier
Is electrode paste harmful to the human body?
The length of the electrode working end and the depth of the furnace should be strictly controlled in accordance with the requirements of the process operation. The graphite electrode paste supplier needs to accurately measure once after each shift. The number of measurements for each phase electrode is not less than three. If the deviation is large, take more measurements. Take the average of the three times with small deviations as the electrode working end length, and accurately grasp the electrode working end length and furnace entry depth to determine the operation plan of the class, and to book the pressure release length of the three-phase electrode of the graphite electrode paste supplier. frequency.
Since the molten pool of submerged arc furnace not only bears strong high temperature, but also is corroded and mechanically washed by charge, high temperature furnace gas, molten iron and high temperature slag, it is necessary to select specific refractory materials. Requirements for refractory materials: high refractoriness, large changes in shape and volume at high temperatures, high temperature strength, good slag resistance, good chemical stability at high temperatures, and various refractory materials should maintain a clean appearance and complete structure , The corner corrugation has no defects and no cracks on the surface. The copper-aluminum composite block is used for crimping. The construction features are simple construction, convenient process supervision, not affected by magnetic fields, and controllable pressure drop. In 2008, an aluminum factory used this method of connection. Due to technical problems at that time, the test failed and the short-circuit explosion accident occurred. However, as the current design of the electrolytic cell becomes larger and larger, the welding construction becomes more and more difficult. Graphite electrode paste supplier should see that the advantages of crimping methods are becoming more and more obvious, and I believe that improved crimping methods will appear and gradually adopted.
(1) Ordinary power graphite electrode. Graphite electrodes with a current density lower than 17A/m2 are allowed, which are mainly used in ordinary power electric furnaces for steelmaking, silicon making, and yellow phosphorus making.
(2) Graphite electrode with anti-oxidation coating. Graphite electrodes coated with an anti-oxidation protective layer form a protective layer that is both conductive and resistant to high-temperature oxidation, reducing electrode consumption during steelmaking.
(3) High-power graphite electrode. Graphite electrodes with a current density of 18-25 A/m2 are allowed, and they are mainly used in high-power electric arc furnaces for steelmaking.
