Problems solved by technology

Due to the deep molten pool of the tundish, the baking effect of the bottom of the tundish and the nozzle is poor. During production, accidents often occur due to the low baking temperature of the nozzle channel, resulting in the freezing of the casting or the nodulation of the nozzle during the casting process, which interrupts the production.

Embodiment Construction

[0016] as attached figure 2 Shown: a method for baking a horizontal continuous casting tundish, which is to install a negative pressure device 8 at the channel of the nozzle 4 of the horizontal continuous casting tundish, so that negative pressure is generated at the channel of the nozzle 4, and the horizontal continuous casting middle The heat flow in the tundish is directed to the nozzle 4 channel, changing the heat flow direction of the original horizontal continuous casting tundish baking, so that the horizontal continuous casting tundish nozzle 4 and the bottom 6 of the horizontal continuous casting tundish are quickly baked. The specific operation process is as follows:

[0017] When baking the horizontal continuous casting tundish, move the horizontal continuous casting tundish to the online baking position and add the tundish cover 2, install the tundish regenerative roaster 3, and then put the tundish in the negative pressure device 8 The large pipe of the exhaust p...

Abstract

The invention discloses a method for baking a horizontal continuous casting tundish. In the method, a negative pressure device is arranged at the position of a water port channel to generate a negative pressure at the position of a water port channel for inducing a heat flow in the horizontal continuous casting tundish to the water port channel in a way different from the heat flow for baking the conventional horizontal continuous casting tundish, and thus, the water port and the tundish bottom of the horizontal continuous casting tundish can be baked quickly. The invention also provides the horizontal continuous casting tundish with the negative pressure device. The horizontal continuous casting tundish is a rectangular and conical container with an opening on the upper end, and consists of the tundish bottom, a front wall, a rear wall and two side faces, wherein a tundish cover is arranged above the tundish; a storage type baking device is arranged on the tundish cover; the tundish water port is arranged below the front wall of the tundish; the negative pressure device is arranged at the position of the water port channel of the tundish; and the negative device consists of an exhaust pipe, a compressed air pipe, an air blower and a bracket.

Description

technical field [0001] The invention relates to the technical field of metallurgical continuous casting, in particular to a method for baking a horizontal continuous casting tundish in steelmaking continuous casting production and a horizontal continuous casting tundish with a negative pressure device. Background technique [0002] The horizontal continuous casting tundish is used as a container for the transition of molten steel between the ladle and the mold, and its nozzle is the channel for the molten steel in the tundish to flow into the mold. In the horizontal continuous casting production, due to the particularity of the process, the tundish molten pool is deep, and its nozzle channel is located under the front wall of the tundish, and because of the small size of the slab produced, the diameter of the nozzle channel is small, so the nozzle channel is A weak link in tundish baking. [0003] The existing horizontal continuous casting tundish in steelmaking and continu...
