Embodiment 2

[0066] Taking the descaling of high-strength steel with conventional width and thicker side scales as an example, refer to the attached figure 1 And attached image 3 , the specific implementation is as follows:

[0067] The metal strip 1 in this embodiment has a width of 1300-1600 mm, and the steel type is a hot-rolled strip of high-strength steel B600L for automobile structure. The scale on the surface of the metal strip 1 of this steel type is difficult to remove, and the thickness of the scale at the edge of the metal strip 1 is obviously greater than that at the middle of the metal strip 1, so there is a problem that it is difficult to remove the scale at the edge. Therefore, for the metal strip of this specification 1 descaling, grinding stick 4 selection as attached image 3 The shown curved profile grinding rod 21 is to strengthen the treatment of the edge scales; during the descaling work of the grinding rod 4, the distance between the middle part of the grinding ro...

Embodiment 3

[0069] Taking the descaling of high-strength steel with narrow width specifications and thicker side scales as an example, refer to the attached figure 1 And attached Figure 4 , the specific implementation is as follows:

[0070] The metal strip 1 in this embodiment is a hot-rolled steel strip with a width of 900-1300 mm and a steel type of high-strength steel B600L for automobile structures. The scale on the surface of the metal strip 1 of this steel type is difficult to remove, and the thickness of the scale at the edge of the metal strip 1 is obviously greater than that at the middle of the metal strip 1, so there is a problem that it is difficult to remove the scale at the edge. The width is narrow, so for the descaling of the metal strip 1 of this specification, the grinding stick 4 is selected as attached Figure 4 The curved contour grinding roller 21 is shown, and the curved contour grinding roller 21 has the ability to move axially. The formula for calculating the ...

Abstract

The invention discloses a device and method for grinding and descaling metal plate belts. The device comprises a descaling box body (2), abrasive particles (3), grinding rollers (4), an abrasive supplying device (5), recovering and feeding channels (6), a collecting groove (10) and a separating and filtering device (13), wherein the grinding rollers are arranged in the descaling box body, and theupper grinding roller and the lower grinding roller are symmetrical about the metal plate belts (1); the recovering and feeding channels are formed in the descaling box body and connected with the abrasive supplying device; the abrasive particles are stored in the abrasive supplying device and input into the descaling box body through the recovering and feeding channels; the collecting groove communicates with the bottom of the descaling box body and the separating and filtering device; an effective particle outlet of the separating and filtering device is connected with the abrasive supplyingdevice; and an ineffective particle outlet of the separating and filtering device is connected with a collecting barrel (19). According to the device and method for grinding and descaling the metal plate belts, the rapid and efficient descaling and the surface cleaning can be carried out on the metal plate belts passing continuously, so that the problems that scales on the edge portions of the metal plate belts are thick and difficult to remove are effectively solved, and the consistent descaling quality in the plate width direction is realized.

Description

technical field [0001] The invention relates to a surface treatment device and method for metal strips, in particular to a grinding and descaling device and method for metal strips. Background technique [0002] Metal materials will form a layer of dense metal oxide on the surface during hot rolling or heat treatment, commonly known as "scale skin". Before the subsequent processing of metal materials, this layer of scale must be removed, otherwise this layer of scale will have an adverse impact on the quality of the finished product and processing equipment in the subsequent process. When rolling, it will not only be pressed into the metal substrate, causing oxide skin pressing defects, but also damage the roll; the scale skin will also affect the coating quality of the workpiece, resulting in missed coating, uneven coating quality, and coating adhesion. Defects such as failure to meet standards. [0003] At present, the traditional scale removal technologies are mainly ch...
