Before connecting the electrode, its threads shallbe firstly cleaned up, and when the nipple is carefully screwed in one end of electrode, the lifting nipple shall be screwed in the other end thereof,without colliding the thread. It is not recommended that, the nipple is directly installed on the electrode being used on the furnace.
The steel wool or metal brush and abrasive cloth are not allowed to clean up the threads of electrode, only the compressed air free of oil and water can be used.
The rotatable elastic hook shall be used, and the soft support pad shall be put below the electrode nipple, to prevent the thread from damaging.
Before connecting the electrode, its hole shall be cleaned up with the compressed air free of oil and water.
The electrode shall be lifted and conveyed on the furnace with the elastic hook for centering, slowly moved down, slightly screwed in, and then, tightened with shroud ring.
The shroud ring is screwed with special calipers according to the specified torque, and either mechanical or hydraulic is adopted. The air pressure equipment shall be screwed to the specified torque.
No contact between end faces of the two electrodes or the contact pressure is too large, will affect the normal use of electrode. Please refer to the torque specified in the Figure.
The electrode holder must be located within the two white warning lines. The contact surface between the holder and electrode shall be frequently cleaned, to keep good contact with the electrode. The water leakage is strictly prohibited in the cooling water jacket of holder.
To avoid the electrode from breaking off, the insulating materials shall not be allowed in the furnace. The working current of electrode shall be adapted to the allowable current of electrode in the Instructions.
To avoid the electrode from breaking off, the block materials should be placed at the bottom of the furnace, and the small materials should be placed at the top thereof.
