Embodiment 1

[0039] What this embodiment grinds is 304 for domestic high-grade stainless steel grinding plate, and its surface quality is N0.4, see Fig. 1, steel plate surface roughness R a The value of 0.04 ~ 0.06. The width is 1000mm, and the finished product thickness is 1.2mm.

[0040] (1) Raw material shot blasting

[0041] 1. Stop adding new steel shot 5 hours before sending the steel strip after raw material annealing, cooling and scale breaking to the shot blasting machine of the production unit.

[0042] 2. The present embodiment is a narrow-width raw material. When the raw material is shot blasted, it adopts low-speed shot blasting under the premise of cleaning the surface (without residual scale on the surface). min.

[0043] 3. The surface has no deep defects and is suitable for the production of raw material coils for frosted boards. The inspectors of each raw material annealing and pickling unit will stamp the seal "Special Material for Frosted Boards" on the upper left co...

Embodiment 2

[0052] What this embodiment grinds is 304 domestic high-grade stainless steel frosted plates, and its surface quality is N0.4. The difference between this embodiment and embodiment 1 is that the third grinding head is installed with a cumulative decay time of 420min. Abrasive belt. Other steps are the same as those in Embodiment 1.

Embodiment 3

[0054] What the present embodiment grinds is 304 for export high-grade product stainless steel abrasive plate, and its surface quality is No. ) See Figure 2, steel plate surface roughness R a The value of 0.06 ~ 0.08. The width is 1300mm, and the finished product thickness is 1.0mm.

[0055] (1) Raw material shot blasting

[0056] 1. Five hours before the raw material annealed, cooled and scale-broken steel plate is sent to the shot blasting machine of the production unit, the shot blasting machine stops adding new steel shots.

[0057] 2. This embodiment is for wide-width raw materials. When the raw materials are shot blasting, the speed of the blasting head is adjusted according to the deceleration ratio of the narrow-width raw materials.

[0058] 3. The surface has no deep defects and is suitable for the production of raw material coils for frosted boards. The inspectors of each raw material annealing and pickling unit will stamp the seal "Special Material for Frosted Bo...

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...
