Description

Technical Field

[0001] The utility model belongs to the technical field of furnace eye opening and plugging of ore-fired furnaces, and particularly relates to an integrated furnace eye opening and plugging device suitable for industrial silicon smelting. Background Art

[0002] The existing high-temperature ore-fired furnace tapping process requires two devices, namely, a furnace eye opening device and a furnace eye blocking device. The furnace eye opening device uses a burn-through technology, which uses a graphite rod to heat the furnace eye by electric arc. This burn-through method will consume the contact part of the graphite rod, and the graphite rod needs to be replaced frequently, and the price of this consumable material is too expensive; a large amount of electricity is required during the burn-through process to ensure the high temperature of the contact position between the stone grinding rod and the furnace eye, resulting in a large amount of electricity consumption and high economic cost; the furnace eye blocking process uses equipment to push mud balls mixed with coke powder, water and a small amount of graphite powder into the furnace eye to achieve the purpose of blocking the furnace. In the prior art, the industrial silicon tapping process uses two devices with furnace eye opening and furnace eye blocking functions to perform the tapping operation. The investment cost of the equipment and its auxiliary equipment is relatively large, the training cost of the early tapping personnel is high and the cycle is long, and the coordination between the equipment is difficult.

[0003] Currently, both devices are large in size and inconvenient to operate. In addition, after the furnace eye is burned through, viscous liquid and other block impurities will appear from the melted furnace eye and graphite rod. Furnace blocking equipment must be used to discharge slag and clear the furnace eye, which prolongs the furnace operation time and causes a large amount of silicon water waste.
