china supplier graphite rod
What are the main types of china supplier graphite rod?
(1) Natural china supplier graphite rod. The natural china supplier graphite rod is an electrode produced with natural flake graphite as raw material. Coal tar pitch is added to natural graphite, after kneading, forming, roasting and machining, it can be prepared into natural china supplier graphite rod, its resistivity is relatively high, generally 15-;m, the biggest disadvantage of natural china supplier graphite rod is The mechanical strength is low and it is easy to break during actual use. Therefore, there are only a few small-sized natural china supplier graphite rods used in some special occasions.
(2) Artificial china supplier graphite rod. Using petroleum coke or pitch coke as solid aggregate and coal pitch as binder, after kneading, molding, roasting, graphitization and machining, an artificial china supplier graphite rod (abbreviated as china supplier graphite rod) can be prepared. The man-made china supplier graphite rod is a high temperature resistant graphite conductive material. According to different raw materials and production processes, china supplier graphite rods with different physical and chemical properties can be prepared and divided into ordinary power china supplier graphite rods, high power china supplier graphite rods and ultra-high power china supplier graphite rods. Carbon material companies, which mainly produce china supplier graphite rods, constitute the metallurgical carbon material industry.
(3) Anti-oxidation coating china supplier graphite rod. The anti-oxidation coating of china supplier graphite rod adopts &;alternating spraying and melting method&; or &;solution dipping method&; to form an anti-oxidation coating on the surface of the processed china supplier graphite rod to reduce the china supplier graphite rod The purpose of oxidative consumption. Since the coating has increased the price of china supplier graphite rod and there are some problems in its use, there is currently no large-scale promotion of the use of anti-oxidation coating china supplier graphite rod in our country.
(4) Water-cooled composite china supplier graphite rod. The water-cooled composite china supplier graphite rod is a conductive electrode used after the china supplier graphite rod is joined to a special steel pipe. The double-layer steel pipe at the upper end is cooled by water, and the china supplier graphite rod at the lower end is connected to the steel pipe through a water-cooled metal joint. The holder is located on the steel pipe, which greatly reduces the external surface area of the china supplier graphite rod exposed to the air, thereby reducing the oxidation consumption of the electrode. However, the operation of connecting the electrode is troublesome and affects the production efficiency of the electric furnace. Therefore, the current China has not yet adopted this type of water-cooled composite china supplier graphite rod.
(5) Hollow china supplier graphite rod. The hollow china supplier graphite rod is a hollow electrode. This product is prepared by directly pressing the electrode into a hollow tube during forming or drilling in the center of the electrode during processing. The other production processes are the same as the ordinary china supplier graphite rod process. The production of hollow china supplier graphite rods can save carbon raw materials and reduce the weight of the china supplier graphite rods; using the hollow area channels of the china supplier graphite rods, alloy materials and other materials required for steelmaking can also be added or required for access gas. However, the molding process for producing hollow china supplier graphite rods is complicated, the raw material saving is limited, and the production yield is low, so hollow china supplier graphite rods have not been widely used.
(6) Recycled china supplier graphite rod. Recycled china supplier graphite rod is prepared by using recycled artificial graphite scraps and powder as raw materials, adding coal tar pitch, kneading, molding, roasting and machining. Compared with coke-based china supplier graphite rods, its resistivity is relatively large and performance indicators are poor. At present, only a small number of small-sized recycled china supplier graphite rods are used in the field of refractory production.
