Being hard and brittle, artificial graphite electrodes shall be specially handled.Proper operation may reduce the consumption and cost.
1.Professional tools should be used for graphite electrode hoisting. The use of crowbars is strictly prohibited. Avoid impact and damage during transportation.
2.The graphite electrode is not allowed to be immersed in rain, snow, or water droplets and should be kept dry. If it is found to be damp, it should be dried before use. The drying temperature should not exceed 120 ℃, and the drying time should not be less than 48h.
3.Do not stack it near clay, slag and other debris to avoid contamination of the graphite electrode surface which will affect the conductive effect.
4.Before connecting the graphite electrode, carefully check whether the electrode joint hole is intact, whether the joint thread is damaged, whether the joint bolt is lost, and when the electrode is hoisted, prevent the ground terminal electrode joint thread from being damaged.
5.The dust and debris in the joints and joint holes should be blown clean with compressed air.
6.The graphite electrode should be tightly connected, and it is not allowed to tilt when connecting. A torque wrench should be used to prevent excessive or small force, and the gap should not be greater than 0.4mm.
7.The electrode holder should be clamped, not loose and in good contact, and no arc should be generated. Otherwise, the joint will become red and oxidized rapidly and broken.
8.When the electrode lifting device of the electric furnace is running, it should be kept stable. After the furnace cover is repaired, check whether the position of the furnace cover is correct. During smelting, use refractory materials to seal the lid of the electric furnace to prevent the flame in the furnace from oxidizing the upper electrode.
9.The holder should be clamped outside the safety line of the electrode joint hole area.
10.When charging the molten pool, the big pieces are on the bottom and the small pieces are on the top. Do not put the charge with poor conductivity on the top. During the melting period, the unmelted charge should be processed in time to prevent the material from collapsing and breaking the electrode.
