Wet-cooled graphite electrodes should be air-dried before application; remove the plastic foam maintenance caps on the graphite electrode holes that are reserved, and check whether the thread of the electric-grade hole is detailed; screw the electric-grade lifting tool (a high-purity graphite material lifting tool is recommended) Into the wall of the electric level hole at the other end of the reserved electric level.

Use a torque wrench to screw the reserved electrical level until the inner holes of the two electrical levels are inseparable (the proper connection gap between the electrical level and the connector is less than 0.05mm). When using a graphite electrode diameter, refer to the allowable current load and current strength of the power stage.

Use oil-free and water-free air compression to remove the surface of the reserved graphite electrode and the thread of the hole; prevent the stainless steel wire ball or metal material from brushing the sandpaper; carefully tighten the connector to the side of the reserved graphite electrode (it is not recommended to immediately connect the connector The electric-level hole wall of the electric level that is put into the furnace and removed can not hit the external thread.

When hoisting the electric level, pad a soft object to the side of the side of the reserved electric level connector to avoid damage to the connector by the road surface; use a lifting hook to reach into the lifting ring of the hoisting tool and hang it. The hoisting level should be stable to avoid The electrical level is loosened by the B terminal or hit with other positioning devices.

Hang the reserved power level above the power level to be connected, and point it down to the power level hole; turn the reserved power level to make the spiral lifting hook and the power level lower together; within the two power levels When the hole distance is 10-20mm, use air compression again to remove the exposed part of the two inner holes of the power stage and the connector; when the power stage is finally completely lowered, it should not be too fierce, otherwise the power stage holes and connectors will be caused by strong impact. Damage to the external threads.
