Embodiment 1

[0031] Such as figure 1 with figure 2 Commonly shown, the metal strip grinding and descaling system includes a descaling device 1 and a strip conveying device.

[0032] The descaling device 1 includes a descaling box 10, the two sides of the descaling box 10 are provided with an inlet and outlet, the descaling box 10 is provided with an upper extrusion plate 11 and a lower extrusion plate 12, and the descaling box 10 is provided with a drive upper The driving mechanism 15 that the extrusion plate 11 and the lower extrusion plate 12 move toward or back to each other;

[0033] The driving mechanism 15 is an electric push rod or a cylinder or a hydraulic cylinder controlled by a solenoid valve. Taking the cylinder as an example, two cylinders are respectively fixed on the top and bottom of the descaling box 10 , and a guide sleeve is provided between the drive shaft of the cylinder and the descaling box 10 . The drive shaft of the cylinder above is affixed to the top of the u...

Embodiment 2

[0047] The difference between this embodiment and Embodiment 1 is that, as image 3 As shown, the descaling device 1 is set as a continuous three-stage structure, which is the first descaling unit 1a, the second descaling unit 1b and the third descaling unit 1c in sequence. The hardware configuration of the three descaling devices 1 is the same, And the extrusion force of each descaling device 1 can be adjusted independently.

[0048] The metal fiber mesh body 14 used in the first descaling unit 1a has a single equivalent diameter of 400-500 μm, and the particle size of the abrasive 140 filled between the pores is 400-600 μm. The material is high-carbon cast steel grit, HRC>60 ;The extrusion force of the clamping metal strip 7 is 2.0~3.0MP metal strip grinding and descaling system; the function of the first descaling unit 1a is to realize the destruction of the surface scale layer and the treatment of large scales; after the first descaling After the unit 1a is processed, mor...

Abstract

The invention discloses a metal strip grinding and descaling system, which relates to the technical field of workpiece descaling, and includes a descaling device and a strip conveying device. The descaling device includes a descaling box, and an upper extruding plate and The lower extruding plate and the descaling box are provided with a driving mechanism that drives the upper extruding plate and the lower extruding plate to move toward each other or back; the opposite sides of the upper extruding plate and the lower extruding plate are provided with grooves; It includes a metal fiber mesh body, the metal fiber mesh body is partially accommodated in the groove, and the metal fiber mesh body is filled with abrasive grains. The invention solves the problems of high cost and poor effect of the descaling system in the prior art, realizes continuous grinding and removal of scales on the surface of metal strips, has low manufacturing cost, and has remarkable descaling effect.

Description

technical field [0001] The invention relates to the technical field of workpiece descaling, in particular to a metal strip grinding and descaling system. Background technique [0002] During the hot rolling process and the subsequent cooling process of the metal strip, a layer of dense metal oxide will be formed on its surface, commonly known as "scale skin". The presence of scale will adversely affect the subsequent processing of metal strips (such as cold rolling, stamping, painting, etc.), so it must be removed. [0003] The traditional descaling methods mainly include pickling and dry shot blasting. The pickling process is currently the most commonly used descaling technology, but pickling has the problem of pollution discharge (waste acid, acid-containing wastewater, acid mist), and the increasingly tightened environmental regulations and policies further limit its application; while dry shot blasting There are also pollution problems caused by dust emissions and safe...
