What are the key points of high temperature frit furnace smelting operation

What are the key points of the high-temperature frit furnace smelting operation? What are the points that must be paid attention to when it is charging? Today, the editor of Huarong will talk to you.

1. Wet tools cannot directly contact molten steel.

2, the following matters must be paid attention to when loading:

①When charging, the height of the stack from the bottom of the furnace should be appropriate, not too high, to prevent the furnace bottom from being damaged by the charge.

② After charging the furnace of the high-temperature frit furnace, if the charge is too high, if the furnace body cannot be opened, the charge must be leveled and the charge must not collide with the furnace lid. When dropping the furnace cover, do not use excessive force to avoid damage to the furnace cover.

③When the molten malleable cast iron is poured into the electric arc furnace from the cupola using the ladle (the double method is used to promote the ancestor, and the composition is adjusted), the operator should stay away from the furnace body to prevent the molten iron from splashing and hurting people.

④When the molten iron enters the high-temperature frit furnace, the inclination of the electric arc furnace should rotate with the height of the ladle, and the molten iron is not allowed to flow out of the charging port.

3. During the smelting process of the high-temperature frit furnace, if the electrical equipment needs to be repaired or the electrode is lengthened, the following matters must be paid attention to:

①The entire control system should be powered off.

②The three-phase indicator must be clearly indicated before proceeding.

③When removing the electrode, first install the aluminum connector and hang it on the hook, and then remove the electrode clamp.

④After unloading the electrode and hooking it up, the operator avoids and pulls out the electrode to avoid injury.

⑤When repairing and replacing electrodes, do not stand on the lid of the high-temperature frit furnace, and use special flat joints.
