Problems solved by technology

Therefore, the three forms of heat transfer (radiation, convection and conduction) will cause the molten iron to lose a lot of heat during the tapping process. At the same time, due to the poor sealing of the tapping process, in order to ensure the environment of the tapping site, the dust removal air volume of the dust collector is increased. Increased smelting cost

Abstract

The invention discloses a seal cover comprising a cover body which is provided with an annular wall and arranged between a taphole and a hot metal ladle. Molten iron flowing out of the taphole enters the hot metal ladle through a cavity of the cover body. The sealing conditions of a tapping site can be improved through the seal cover, and the air volume of a dust collector can be reduced; the radiation and thermal convection of the tapping process are reduced, and the molten iron heat loss of the tapping process can be reduced greatly.

Description

technical field [0001] The invention relates to the technical field of blast furnace production, in particular to a sealing cover. Background technique [0002] During the tapping process of the blast furnace, the temperature of molten iron is 1400-1550°C, which is much higher than the ambient temperature; the drop of molten iron from the casting plant to the ladle is large; There is no sealed space formed in the iron process. Therefore, the three forms of heat transfer (radiation, convection and conduction) will cause the molten iron to lose a lot of heat during the tapping process. At the same time, due to the poor sealing of the tapping process, in order to ensure the environment of the tapping site, the dust removal air volume of the dust collector is increased. Increased smelting costs. [0003] Therefore, how to provide a sealing cover to reduce the heat loss of molten iron is a technical problem to be solved urgently by those skilled in the art.
