Graphite electrode, which is made of petroleum coke and needle coke as raw materials and coal tar pitch as binder, is made by calcination, batching, kneading, pressing, roasting, graphitization and machining. It is a conductor that releases electric energy in the form of electric arc to heat and melt the furnace burden. According to its

The use of graphite mold is mainly its high temperature resistance, such as pure copper casting temperature of about 1200 degrees, graphite at this temperature is still stable, thermal barrier and cold shrinkage are very small, can be neglected. On the other hand, lubrication is relatively good, the solidification process of metal liquid is not

(1) Ordinary power graphite electrode: Allow the use of current density of less than 17a/cm 2 graphite electrode, mainly used in steelmaking, smelting silicon, refining of yellow phosphorus, such as ordinary power electric furnace. (2) Anti-oxidation coating graphite electrode: The surface coating a layer of antioxidant protective layer of graphite electrode, forming both conductive and

Application Method of Graphite electrode 1. By the wet graphite electrode, before use to dry. 2. Remove the foam protective cap on the hole of the standby graphite electrode and check whether the thread is intact in the electrode hole. 3. With oil-free and water compressed air to clean up the spare graphite electrode surface and hole

At present, the market price of graphite electrode in China is at a relatively low level, and it is unlikely that the market will continue to decline substantially. From the beginning of June to now, the mainstream transaction prices of ultra high, medium and small specifications and super large graphite electrodes are mainly stable, and the overall

Lantern Festival is a traditional festival in China. The formation of the custom of Lantern Festival has a long process, which is rooted in the ancient custom of turning on lights and praying for blessings. Turning on the lights and praying for blessings usually begins on the 14th night of the first month. On the
