Use special hoist tools to hoist graphite electrode. It is strictly forbad to prize electrode ends up with crowbar. It must be handled with great care during transport to avoid being struck. 2. Graphite electrode must be kept away from being moistened or wetted by rain, snow and water, and must be kept dry. 3. Carefully checking before making connection, make sure that socket and nipple thread is not damaged, nipple pitch plug is in. 4. Blow the nipple and socket threads with compressed air. 5. It must be dried in the furnace before use, the drying temperature in the furnace should be less than 150,the drying period should be more 30 hours 6. Graphite electrode must be connected and contacted closely and straightly.Use moment spanner for connecting electrode with suitable force. Mustnt decline. 7. The holding device must hold the electrode tightly, good contact and no arc. 8. To avoid the electrode breakage, put the large materials in lower part and small materials in the upper part. Insulating materials should not be put into the furnace. The working current of electrode must be conformity with the allowable current of electrode in the instructions.
Xinhong carbon advantage: Strictly control of raw material ensures it is from the best origin; Advanced production technology & facilities &experienced workers; Strict quality tracing system to ensure each ge excels buyer needs; Technical assistance & after service are available whenever needed; Sufficient stock in factory to ensure competitive price&fast delivery; Graphite electrodes Graphite electrode is made of petroleum coke, needle coke, and bonding coal pitch. Its production process is: calcining, dosing, mixing, forming, baking and impregnation, graphitization in a high temperature of over 3000c, then precision machining. Graphite electrode is acting as a conductive body which release heat in the form of arc for heating and melting steel in the furnace.According to the application, it can be divided into regular power(rp), high power(hp) and ultra high power(uhp). Graphite electrode is an important conductive material in smelting industry with good electrical conductivity, thermal conductivity and high mechanical strength, good corrosion resistance under high temperature. Graphite electrode is widely used in eaf, lrf, submerged arc furnace(producing ferroalloy, pure silicon, yellow phosphorus, calcium carbide etc), resistance furnace (such as the graphitization furnace, glass melting furnace and silicon carbide furnace etc). Packed in wooden crate or as your requirment.
Ordinary power graphite electrode products are mainly suitable for electric arc furnaces used in steelmaking. We are a manufacturing company that produces, sells, exports and provides a wide range of graphite electrodes. Our products have good electrical conductivity and perform particularly well under harsh smelting conditions.RP graphite electrode is mainly used for regular power electric arc furnaces to smelt scrap steel, silicon and yellow phosphorus.
