Q:How should carbon deposits be treated?: At certain temperature, can make alloy and carbon can react in the engine surface coated with a layer of graphene film, graphene nano particles can fill the pores, wear scratches, on the friction surface repair function.

Q:Is graphite electrode good for foreign trade?: Foreign sales commission depends on the price you talk to the customer, and the profit is objective.

Q:What is anodized graphite?: Electrochemical graphite is made of graphite, coke and other raw materials, placed in the high temperature of more than 2500 degrees in the furnace, processed into products.

Q:What is the graphite furnace electrode with a diameter of 400?: The variety and specifications of graphite electrodes used in modern EAF steelmaking are mainly determined by the technical parameters of the steelmaking furnace.

Q:How long is the graphite electrode machining cycle?: When the cut depth is less than 0.2mm, the graphite will break down very little, and the surface quality of the side wall will be better.

Q:Jiqiu conductive graphite electrode, how to compare with copper is relatively large resistance value?: This is not a good estimate of the sheet graphite resistance after 5mm

Q:Graphite powder produced by graphite electrode and what we usually call graphite is a kind of thing?: Coal tar pitch as binder is made by calcination, batching, kneading, pressing, roasting, graphitization and machining

Q:Graphite electrode press device: (1) ordinary power graphite electrode, using graphite electrode with current density lower than 17A / cm 2, is mainly used in steel-making, smelting silicon, refining yellow phosphorus and other common power electric stove(2) anti oxidation coating graphite electrode. The surface is coated with an anti oxidation protective layer of graphite electrode to form a protective layer which has both conductive and high-temperature oxidation resistance, thus reducing the electrode consumption during steelmaking

Q:Carbon graphite electrode and what is the difference?: The material is composed of carbon carbon, but without graphite, after molding sintering temperature is only more than 1000 degrees, no graphitization.

Q:What does graphite electrode GSK mean?: Graphite board material is GSK, GSK refers to model specifications
