User Manual

Graphite is a brittle material, with limited flexibility.

For reducing the consumption & cost, please handle your graphite electrodes carefully.

Brife Introduction Of How To Use Graphite Electrodes

transportation-caution

Transportation

Graphite electrode should be covered with rain-proof tarpaulin in the process of transportation.

transportation-caution

Forklift Transport

Note 2: Forklift Transport Be careful when transporting and pilling the electrodes with forklift and avoid collisions. One layer of goods at a time, notice the balance and alignment to avoid falling or breakage

transportation-caution

Loading Caution

When loading and unloading with forklift, additional wire rope must be used and steel wrapping tape can not be employed directly to fetch electrode.

storage-caution

Note 4: Storage Caution

Electrode should be stored in clean and dry place. When stocked in open area, it should be covered with rain-proof tarpaulin and the number of piling layers ought not to exceed four.

dried-before-use

Note 5: Precautions Before Use

Electrodes should be dried next to electric furnace before using. The temperature should not exceed 120 °C and the time should not be less than 48 hours.

wrapping-cut-method

Note 6: Wrapping Tape Cutting

When using electrode, special tools should be employed to cut the steel wrapping tape, and crane should not be adopted to avoid bursting.

installation-caution

Note 7: Installation Caution

Please clean the electrode threads first before connection, then screw the nipple into one end of the electrode. Don’t touch the thread, and don’t put the joint directly into the working electrode on furnace.

thread-clean-caution

Note 8: Electrode Thread Cleaning

Steel-wire ball, metallic brush or emery cloth is not allowed for cleaning electrode thread, but compressed air free of oil and water is available.

hoisting-attention

Note 9: Hoisting Attention

Use revolved resilient hanger and put soft cushions under the electrode nipple to avoid breakage of thread.

thread-clean-compressed-air

Note 10: Connection Caution

Before connecting, clean the screw thread of electrode with compressed air free of oil and water.

nipple-center-axis

Note 11: Nipple Connection

When connecting, the electrode is aligned with the center axis of the nipple to which is the connected.

electrode-tight-caliper

Note 12: Tighten the Electrode

Use special caliper to tight electrode according to rated torque by mechanical way, hydraulic pressure or wind pressure equipment should also be available.

clamp-holder-position

Note 13: Electrode Clamp Position

Electrode clamp holder must be placed between the two white guard lines. Clamp holder and interfaces of the electrode must be cleaned regularly to keep good touch with electrode. Cooling water jacket of the clamp holder should be tight to prevent water leakage.

electrode-working-current

Note 14: Graphite Electrode Selection

To avoid the electrode breakage, 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.

large-material-place

Note 15: Large Material Smelting

In order to avoid electrode breakage, put the large materials in lower part and small materials on the upper part.

nipple-connecting-torque

Note 16: Nipple Connecting Torque

If the two poles of electrode are 6untouched or touched in overpressure, this may cause bad effect. Please refer to the rated torque in the below form.
