Abstract

The invention relates to an air-blowing type descaling box device which comprises a descaling box. The descaling box is provided with a cavity structure and is internally provided with an upper nozzle and a plurality of flow guide plates, and the flow guide plates are vertically arranged and are inclined towards one side of the upper nozzle; the flow guide plates are arranged in the same direction at intervals, the first flow guide plate on one side in the direction is adjacent to the upper nozzle, a gap is formed between the second flow guide plate adjacent to the first flow guide plate and the top of the descaling box, and the top of the second flow guide plate is arranged downwards relative to the flow guide plates on the two sides; and an air outlet of the upper nozzle is located below the bottom horizontal plane of the first flow guide plate, and the air outlet direction of the upper nozzle inclines towards one side of the flow guide plate. The amount of oxide scales of a heating furnace is reduced, and the labor intensity is reduced. The oxide scales can be effectively prevented from splashing all around.

Description

technical field [0001] The invention belongs to the technical field of purging and descaling of continuous casting slabs, and in particular relates to an air blowing type descaling box device. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Before the continuous casting slab enters the heating furnace, the casting slab is in contact with air at a relatively high temperature, and a layer of iron oxide scale is formed on the surface of the casting slab, which not only affects the heat transfer of the heating furnace to the continuous casting slab, but also intensifies the heat transfer to the heating furnace. Environmental pollution leads to increased production costs and r...
