But it in use, adopts the hot rolling ubiquity roll coil of strip head 50m～200m lower surface of this technology to scratch phenomenon; And the scratch streak of middle made-up belt lower surface just results from the roller of uncoiling mechanism and the perching knife head is adjacent to and along in the process of slippage under the coil of strip cylindrical.Its reason is as follows:
1, in uncoiling process, between cold conditions shovel head and the tropical base volume excessive thrust is arranged, sliding friction between the two very easily causes the scratch on made-up belt surface.
2, the nose angle of " right angle " shape of shovel two end, in uncoiling process, can produce every now and then and contact the tropical base volume that is in rotation and double swerve, make the cylindrical of the direct scratch made-up belt volume of nose angle, thereby on same width, stay the lengthwise streaking of discontinuity at the made-up belt lower surface of being left.
3, in uncoiling process, the partial oxidation iron filings are bonded at the shovel head and go up indefinite " dross " in formation position, and these " drosses " form rectangular continuous scratch streak when contacting with made-up belt volume cylindrical.
4, in uncoiling process, because uncoiling arm shovel head is to be close to the hot strip steel surface from the top down to slide, and the shovel head is the cold conditions metal, very easily produces to scratch.
Particularly particularly evident for stainless production, because the rolled stainless steel temperature is higher, hot state lower surface scratches and is difficult to healing or elimination; And, these scratch streaks are fatal for the quality influence of stainless steel hot-rolling finished product, because the scuffing at stainless steel hot state lower surface is difficult to be eliminated in the seven frame mm finishing mill unit in step of back, cause the serious quality problems of stainless steel hot-rolling finished product volume, so problem perplexs countries in the world hot-rolled stainless steel manufacturer always.
Summary of the invention
