Mirror-surface roller processing method and method for processing mirror-surface aluminum board by utilizing mirror-surface roller

Abstract

The invention provides a mirror-surface roller processing method and a method for processing a mirror-surface aluminum board by utilizing the mirror-surface roller. A grinding machine is utilized to grind roller blank into a finished product mirror-surface roller with roughness smaller than or equal to 0.006 microns; and then, a rolling mill with the finished product mirror-surface roller is utilized to roll aluminum board blank into the mirror-surface aluminum board with roughness smaller than 0.006 microns. According to the invention, the mirror-surface roller is processed by virtue of a grinding process, and the mirror-surface roller is grinded on the grinding machine until the roughness is smaller than or equal to 0.006 microns, so that a complex process of grinding and then polishing in the prior art is replaced. The grinding process does not use a polishing machine, so that the grinding time of the mirror-surface roller is shortened to be about 6 hours, and therefore, polishing corrosion is avoided; the yield of the mirror-surface roller is higher than 85%; compared with a polished mirror-surface roller, the grinded mirror-surface roller has better durability, a long service life and lower cost. The rolling mill with the mirror-surface roller is utilized to roll out the mirror-surface aluminum board, and an original manufacturing method for polishing on the polishing machine is replaced, so that various quality problems, caused by the defects of the polishing process, of the mirror-surface aluminum board, are effectively avoided.

Description

technical field [0001] The invention relates to a method for processing a mirror-surface roll and a method for processing a mirror-surface aluminum plate by using the mirror-surface roll. Background technique [0002] In the prior art, the rolling mill can only be used to produce common aluminum sheets, and cannot directly produce mirror-faced aluminum sheets. This is because the roughness of the work rolls on the rolling mill itself is not low enough. If you want to use a rolling mill to directly roll out mirror-faced aluminum sheets, the work rolls must be mirror-faced rolls. At present, for the processing of the surface of the mirror roll, the roughness of the roll can only be ground to 0.02 micron on the grinding machine, and then the roughness of the roll is reduced to below 0.01 micron by the polishing machine, so as to meet the requirements for rolling the mirror aluminum plate. However, this processing method of first grinding and then polishing has the following di...

Problems solved by technology

However, this processing method of first grinding and then polishing has the following disadvantages: 1. The polishing time is long, which takes about 48-60 hours; 2. Long-term polishing is easy to cause corrosion of the roller surface; The finished product rate of the roll is less than 60%. 4. The service life of the finished mirror roll is short, usually 2-6 hours; 5. The processing cost is high, and the average mirror roll is more than 7,000 yuan
