How and Why to Punching Furnace
2017-02-13
Punching furnace is to stir the inside of the bulk of the charge and the material of the sintering area, in order to increase the material surface permeability, expand the crucible, the furnace furnace to speed up the chemical reaction.
Ferrosilicon smelting, the silica at high temperatures still have a great bond. If not timely pound furnace, affecting the permeability, resulting in fire, dry down, the furnace reaction speed and Liao Liao speed are slow and so on. Obviously, the stove is an important operation to increase the material surface permeability and expand the crucible volume.
Punching furnace requirements:
1. Punching furnace faster, and strive to reduce the heat loss.
2. Mix the side of the furnace or add coke.
3. Punching furnace to adapt to the air permeability of the region really pick open, pay attention to less damage to the crucible. The round bar of the punching machine is not allowed to bump the electrode and the copper tile.
4. Punching large pieces of sticky material should be pushed to the center and covered with charge.
Capacity of small electric furnace stove operation, should be flexible to master.
5. Punching furnace is completed, should be timely feeding, so that the electrode into the stove charge.
