A kind of molten steel jacket at the top feeding place of oxygen-enriched side-blowing furnace

Abstract

The invention discloses a steel water jacket at the feed position of the furnace top of an oxygen-enriched side-blown furnace. The steel water jacket comprises a bottom plate and a cover plate. The bottom plate and the cover plate form a cavity. The outer side of the bottom plate and the outer side of the cover plate are connected with a rib plate with holes. The two ends of the bottom plate are connected with vertical plates. The vertical plates are connected with a bottom steel plate through triangular rib plates. A plurality of claw hooks are arranged below the bottom plate. A top rib plate is arranged above the cover plate. Water inlet pipes and water outlet pipes are arranged on the outer side the upper portion of the cover plate. The center of the bottom plate, the center of the cover plate and the center of the top rib plate are each provided with a through hole corresponding to a charging port. A fixing device is arranged at the through holes and comprises a flange, a flange connecting pipe and flange rib plates, wherein the flange is welded to the flange connecting pipe, and the flange and the flange connecting pipe are connected with the cover plate through the flange rib plates. The steel water jacket at the feed position of the furnace top of the oxygen-enriched side-blown furnace is simple in structure and convenient to install and replace, is installed at the feed position of the furnace top, and can protect a feed port of the furnace top against damage, improve the safety performance of the furnace and prolong the service life.

Description

technical field [0001] The invention relates to the technical field of copper smelting equipment, in particular to a molten steel jacket at the top feeding place of an oxygen-enriched side-blown furnace. Background technique [0002] In the field of copper smelting technology, side blowing furnace is a common production equipment. At present, the roof and furnace wall of most side-blowing furnaces are made of refractory materials. The roof is made of refractory materials. The high-temperature flue gas in the furnace is easy to wash and corrode the roof, which will eventually shorten the life of the side-blowing furnace. In addition, the molten slag splashed in the furnace is easy to accumulate on the furnace roof, and when the large nodules fall off, it is easy to peel off the refractory bricks, resulting in faster burning of the refractory bricks at the feed inlet of the furnace roof, and it is not easy to replace, and the furnace roof adopts Made of durable materials, the...

At present, the roof and walls of most side-blowing furnaces are made of refractory materials. The roof is made of refractory materials. The high-temperature flue gas in the furnace is easy to wash and corrode the roof, which will eventually shorten the life of the side-blowing furnace.

In addition, the molten slag splashed in the furnace is easy to accumulate on the furnace roof, and when the large nodules fall off, it is easy to peel off the refractory bricks, resulting in faster burning of the refractory bricks at the feed inlet of the furnace roof, and it is not easy to replace, and the furnace roof adopts Built of durable materials, the stove top is very heavy and difficult to install and disassemble
