Guidance of using

1.

Use special hoist tools to hoist graphite electrode. It is strictly forbidden to prize electrode ends up with crowbar. It must be handled with great care during transportation to avoid damage.

2.

Graphite electrode must be kept away from being moistened or wetted by rain, snow and water, and must be kept dry. It must be dried in the furnace before use. The drying temperature in the furnace shall be less than 100℃. The drying period shall be not less than 48 hours.

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 socked 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.
