Embodiment Construction

[0012] The operation steps for grinding 00 section of continuous casting coil are:

[0013] 1. Place the blank (stainless steel continuous casting coil slab 00 section) on the grinding machine trolley; 2. The grinding head feed is 40mm, the reduction parameter is 2500, and the surface is normally ground twice; 3. The grinding head feed The amount of 30mm, the reduction parameter is 3000, and the grinding head is 3 meters away from the billet end; 4. The grinding head feed is 30mm, and the reduction parameter is 3000, and the grinding head is 2 meters away from the billet end. The feed volume is 30mm, the reduction parameter is 3000, and the grinding is again 1 meter away from the billet end; 6. Check the surface, if there are sporadic inclusion defects, the grinding head feed is 40mm, the reduction parameter is 2500, and the point grinding treatment Until there are no visible defects, turn the steel (turn the blank over) and use the same method for grinding once.

Abstract

The invention belongs to the field of slab polishing, and particularly relates to a polishing method for a stainless steel continuous casting rolled slab 00 section. The method comprises the steps of step 1, placing the stainless steel continuous casting rolled slab 00 section onto a polisher lathe and polishing the superficial black skins of the 00 section, wherein the grinding head is 40mm in feed rate and 2500 in pressing parameter; step2, polishing once at the position 3m away from a slab outlet end with the grinding head feed rate being 30mm and the pressing parameter being 3000, polishing once at the position 2m away from the slab outlet end and polishing once at the position 1m away from the slab outlet end; step 3, if a few blended defects still exist, performing point polishing with the grinding head feed rate being 40mm and the pressing parameter being 2500 until naked eyes cannot see the defects; step 4, adopting the same steps as the steps 1, 2 and 3 to perform polishing on the second face after steel turning. The polishing method solves the problem that the blended impurities can not be cleaned in the polishing process of the stainless steel continuous casting rolled slab 00 section.

Description

Technical field [0001] The invention belongs to the field of slab grinding, in particular to a method for grinding 00 section of a stainless steel continuous casting coil slab. Background technique [0002] The 00 section of stainless steel continuous casting coil slab (the first section of rolling) has remained high after rolling for many years. It has always been the main factor affecting the quality index after rolling, and it is also the key to improving the quality of cast slabs. It is necessary to improve the grinding quality of the 00 section of the continuous casting coil slab, so as to reduce the waste products after the 00 section of the coil slab. [0003] Because the 00 section of the continuous casting coil slab must undergo pouring, speed increase, and mold level automatic control process operations during the production process, the first 3 meters of slabs have the lowest pouring temperature and the largest mold level fluctuations. During the manual control period, ...
