Problems solved by technology
[0007] The purpose of the present invention is to solve the problem that the work rolls used in the strip steel alkali scrubbing process have poor stability during high-speed operation and make the work rolls easily vibrate during use, and provide a method for manufacturing work rolls with high dynamic balance performance. The shaft shoulders at both ends of the work roll are finely ground before cleaning the tank so that the outer diameters of the shaft shoulders at both ends are the same, and the shaft shoulders at both ends are respectively supported by two identical supports, so that the axis of the roll body is parallel to the direction of the milling groove of the boring head. And adopt the method of rotating the work roll after milling 0.2mm each time to carry out circular groove milling, so that the shape, width and depth of the three brush grooves on the roll body are the same, thereby ensuring that the processed work roll has a high dynamic balance performance

The invention discloses a method for manufacturing a work roll with high dynamic balance performance, and belongs to the field of work roll manufacturing technology. In the manufacturing method of the work roll of the present invention, before milling grooves, the shaft shoulders at both ends of the work roll are finely ground to make the outer diameters of the two shaft shoulders the same, and then the shaft shoulders are erected on two identical supports, thereby ensuring that the work roll roll The axis of the body is parallel to the groove milling direction of the boring head, and the milling groove is carried out by rotating the work roller after each milling 0.02mm, so as to ensure that the shape, width and depth of the three brush grooves are the same, and can be processed in real time The last work roll has high dynamic balance performance.
Description
technical field [0001] The invention relates to the technical field of work roll manufacturing technology, and more specifically, relates to a method for manufacturing work rolls with high dynamic balance performance. Background technique [0002] Galvanized steel strip is a strip-shaped steel obtained by complex physical or chemical reactions between the steel substrate after cold rolling or hot rolling and the molten metal zinc plating solution. Because of the compact zinc-iron alloy coating formed on its surface, it has strong corrosion resistance. [0003] A good surface condition and cleanliness of the steel strip before hot-dip galvanizing is a prerequisite for obtaining a good coating. It is generally difficult to obtain a bright coating with good adhesion and excellent corrosion resistance when hot-dip galvanizing is carried out on the surface of the strip steel with oil stains. Therefore, the strip steel must go through a cleaning process before entering the annea...
