(4) Water-cooled composite graphite electrode.
The water-cooled composite graphite electrode is a conductive electrode used after joining the graphite electrode with a special steel pipe, and the double-layer steel is located at the upper end.The inner part of the pipe is cooled by water, and the graphite electrode at the lower end is connected to the steel pipe through a water-cooled metal joint, and the electrode holder is located on the steel pipe, which can be greatly reduced.The surface area of the graphite electrode exposed in the air is reduced, thus the oxidation consumption of the electrode is reduced, and the operation of the dry connecting electrode is troublesome and affects the production efficiency of the electric furnace.Therefore, this kind of water-cooled compound graphite electrode has not been used in our country at present.
(5) Hollow graphite electrode, hollow graphite electrode is hollow electrode.
The preparation of this product is directly pressed into a hollow tube when the electrode is formed or during processing.The center of the electrode is drilled, and other production processes are the same as those of ordinary graphite electrodes.The production of hollow graphite electrode can save carbon raw materials and reduce hoisting graphite electrode.Weight: using the hollow zone channel of the graphite electrode, the alloy and other materials needed for steelmaking or the required gas can be added.But the production of hollow stone and other electricity.The molding process of the pole is complex, the saving of raw materials is limited, and the rate of finished products is low, so the hollow graphite electrode has not been widely used.
(6) regenerated graphite electrode.
The recycled graphite electrode is made from recovered artificial graphite particles and powders, and coal tar pitch is added to it after kneading, molding, roasting and.It can be prepared by machining.Compared with coke-based graphite electrode, its resistivity is higher and its performance index is poor. at present, there is only a small amount of recycled graphite electricity.Extreme products are used in the field of refractory production.
