Embodiment Construction

[0029] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] As shown in the figure, the electric furnace slag-less tapping method in the present invention includes step (1), setting up a retaining wall 3 at the front of the tapping hole 2 in the eccentric tapping electric furnace 1, the bottom and side walls of the retaining wall 3 Corresponding to the closed connection with the furnace bottom and furnace wall of the eccentric tapping electric furnace 1, so as to separate the furnace chamber of the eccentric tapping electric furnace into two regions of the electric furnace molten pool area 1a and the eccentric area 1b; step (2), on the retaining wall 3, open A long and narrow tapping launder 4 communicates with the tapping hole of the electric furnace molten pool area 1a and the eccentric area 1b. When tapping, unlike the traditional electric furnace, the molten steel must pass through the ta...

Abstract

The invention belongs to the metallurgy field and particularly relates to a less-slag tapping method for an electric furnace and a slag baffling device. A baffling wall which divides a furnace chamberof an eccentric tapping electric finance into an electric finance melting tank region and an eccentric region is arranged in the eccentric tapping electric finance, a long and narrow tapping runner for communicating the electric finance melting tank region with the eccentric region is formed in the baffling wall, and meanwhile, a replaceable slag baffling bar is arranged on the tapping runner andis used for baffling steel slag, so that the take-out amount of slag in the later tapping period is reduced. According to the method and the device, molten steel slag inclusion is reduced, and the quality of the steel is improved; and the slag-off procedure during the production is reduced, and the energy loss and the metal loss are reduced, so that the total economic benefit of electric furnacesteelmaking is substantially increased.

Description

technical field [0001] The invention belongs to the field of metallurgy, and in particular relates to a method for tapping steel with less slag in an electric furnace and a slag retaining device. Background technique [0002] Reducing the amount of slag in the molten steel during the tapping process of the electric furnace is an important direction to improve the steel quality, reduce the slag removal link (energy saving and consumption reduction) and increase the yield. [0003] In the process of steelmaking, whether it is an electric furnace or a converter, a large amount of slag will be produced. These slags float on the surface of the molten steel and will flow into the ladle together with the tilting of the furnace at the later stage of tapping. Generally speaking, this slag is mixed into the steel. The quality and production process of steel are unfavorable, as if harmful components are added, and the increase of slag removal links will cause energy and metal loss, whi...
