Notes of usage:
Being hard and brittle, artificial GE shall be specially handled. Proper peration may reduce the consumption and cost.
1. Use special hoist tools to hoist electrodes. It is strictly forbid to prize electrodes ends up with crowbar. It must be handled with great care during transport to avoid damage.2. GE must be kept away from being moistened or wetted by ram, snow and water, and must be kept dry. It must be dried in the furnace before using. The drying temperature in the furnace shall less than 120ºC. The drying period shall be not less than 48hours.3. Not to be stored up near clay, slag etc. to avoid surface pollution and increasing resistivity.4. Carefully checking before connection, make sure that the socket and nipple thread is not damaged, nipple pitch plug is in. Nipple screw shall not be damaged during lifting. 5. Blow the nipple and socket threads with compressed air.6. GE must be connected and contacted closely and straigtly. Use moment spanner for connecting electrode with suitable force. The gap between elelctrodes shall be less than 0.4mm.7. The holding device must hold the electrode tightly, good contact and non arc. Otherwise, the connecting area will get red, oxidized and thin, leading breakage.8. Threaded portion of nipple socket shall not be damaged during hoisting by metal plug. Hoisting plug shall pin out and keep nipple socket clean.9. Lifting device of electrode must move stably when moving electrode. Carefully check the position of the furnace cover after being repaired. To seal the cover with refractory to prevent up electrode from being oxidized by fire.10. The holding device shall hold the electrode beyond the socket area.
11. For charging the furnace, the large scrap should be put at the bottom. The small ones on the top, charge material with low electric conductivity shall not been put pn the top. In the course of melting, unmelted material shall be taken in time to avoid electrode breaking by falling material.
APPLICATIONGraphite electrode is a conductive material for smelting iron and steel, brown corundum, metal silicon and so on in electric furnace. Circuit steelmaking
