Embodiment 1

[0035] Such as figure 1 As shown, the descaling system for metal long products includes a descaling device, a washing device, a drying device and a circulation system. The workpiece enters the descaling device for descaling, then enters the rinsing device for surface cleaning, and finally enters the drying device for drying. dry to complete the entire process. The descaling device includes a fluidizer 1. In this embodiment, there are two fluidizers 1, and the two fluidizers 1 are arranged symmetrically above the workpiece. The ejectors 1 have their own independent drive motors for connection and transmission. The transmission mode is not limited to direct drive, and belt drive, gearbox drive or coupling drive can also be used. The ejector 1 sprays a mixture of abrasives and water to clean the workpiece. Surface scales.

[0036] The flushing device includes a flushing ring 2, which is supplied with water by a circulation system, and the inner wall of the flushing ring 2 is pr...

Embodiment 2

[0050] The difference between this embodiment and Embodiment 1 is that, as figure 2 As shown, there are two sets of second delivery pipe sets 70, one set of second delivery pipe sets 70 is connected to the water inlet end of the pumping device, and the other set of second delivery pipe sets 70 is connected to the inlet end of the filtration system. The third delivery pipe group 80 is provided with two groups, one group of the third delivery pipe group 80 is connected to the flushing device, and the other group of the third delivery pipe group 80 is connected to the mortar distributor 60 . That is to say, two sets of second conveying pipe sets 70 supply water to the pumping device and the filtration system respectively, and two sets of third conveying pipe sets 80 respectively supply water to the flushing device and the mortar distributor 60, so that the water supply volume is easier to control and the production efficiency is higher .

Embodiment 3

[0052] The difference between this embodiment and Embodiment 1 is that, as image 3 As shown, there are two jets 1, and the two jets 1 are arranged symmetrically above and below the workpiece.

Abstract

The invention discloses a descaling system for long metal materials, and relates to the technical field of workpiece descaling. The descaling system comprises a descaling device, a flushing device, a collecting box, a pumping device, a first water tank, a second water tank and a filtering system, wherein a sand inlet end of the pumping device is connected to the bottom of the collecting box, and a outlet end of the pumping device is connected with the descaling device through a mortar distributor; the upper portion of the collecting box is connected with the upper portion of the first water tank through a first conveying pipe group, and the lower portion of the first water tank is connected with the inlet end of the filtering system and the water inlet end of the pumping device through a second conveying pipe group; a water discharge end of the filtering system is connected with the upper portion of a second water tank; the lower portion of the second water tank is connected with the flushing device and the mortar distributor through a third conveying pipe group, and the upper portion of the first water tank is connected with a water supplementing system. According to the descaling system, continuous cyclic utilization of grinding materials and water is effectively achieved, and cyclic utilization of media is more efficient and stable.

Description

technical field [0001] The invention relates to the technical field of workpiece descaling, in particular to a descaling system for metal long products. Background technique [0002] The outer scales of metal long products, because in the metallurgical manufacturing process, the continuous casting billets of long products must undergo a series of high-temperature rolling to achieve the cross-sectional shape required by the end user, and then through open natural cooling in the factory building, to be finally delivered to the user. However, during this cooling process, the outer surface of the long material has sufficient exposure to oxygen in a high-temperature environment, resulting in the formation of a dense oxide layer during the high temperature period, which is composed of multiple oxide stacks. This oxide layer must be effectively removed before the long material is subsequently welded, anti-corrosion coated, etc. [0003] Traditional cleaning methods include dry sh...
