Coil Grinding Lines

Product description

During the production of hot strip, surface defects can arise that cause quality losses during the subsequent production processes. These surface defects are transferred to the rolls and roll surfaces, with the result that they are applied to the strip again. By using a strip grinder, the strip is freed from damaging surface defects.

The next process is grinding in order to obtain a structured surface and to improve flatness.

During grinding, the strip is cooled by mineral oil and freed from grinding sludge. Most of the oil, which is now on the strip, is removed by wipers or squeegee rolls at the end of the grinding cabins. After grinding, the oil is cleaned with the aid of a vacuum belt filter so that it can be reused. The rest of the grinding swarf is treated, briquetted, and can be smelted during steel production.
