Grinding method for high-grade stainless steel frosted plate surface

Abstract

Provided is a grinding method of the surface of a high-grade stainless steel frosted plate. The steps of grinding method include that, (1) throwing pills, firstly, after a steel plate is annealed, cooled and scale broken, the steel plate is taken into a pill throwing machine, new steel pills are stopped from being added at the time of five hours earlier of the steel plate being taken into the pill throwing machine, then, when narrow materials throws pills, throwing head speed is 1850-2000 revolutions per minute, and when broad materials throws pills, throwing head speed is 1600-1700 revolutions per minute, (2) rolling overall pressure rate of a cold rolling being equals to or over 65%, (3) starting a first upper grinding head, a second upper grinding head and a third grinding head in the grinding time, firstly, the grain size of a abrasive band is polished, the new abrasive band is firstly ground to be attenuated on other steel coils, an abrasive band of the attenuation equal to or over 100 minutes and an abrasive band of the attenuation equals to or over 200 minutes, secondly, the abrasive band of the attenuation which equals to or over 100 minutes is mounted on the first upper grinding head, and then two abrasive bands of the attenuation equal to or over 200 minutes are installed on the second upper grinding head and the third grinding head to be precisely ground. The grinding method improves the surface quality of the frosted plate of the cold rolling and reduces the surface defects of the steel plate.

Description

technical field

[0001] The invention relates to a grinding method for the surface of a high-grade stainless steel frosted plate. Background technique

[0002] Stainless steel frosted plates are mainly used in products, decoration, construction and other industries. Due to the particularity of their use, stainless steel frosted plates have very high requirements on the surface. After entering 2006, the export volume of frosted plates has continued to increase, while foreign frosted plates Users have stricter requirements on the surface quality of products, not only high-grade and defect-free surface quality, but also strict requirements on the length, depth and uniformity of the grinding wire. Frosted boards have a wide range of uses, and are often used in elevator decoration, architectural decoration, electrical products, kitchen equipment, decoration and decoration, etc. The different uses of the products determine different requirements for the surface, especially the dome...
