five days a crude steel mills for Pocket increase

摘要

A skin pass mill for increasing the oil pockets of a steel sheet is provided to remove peaks from a steel sheet by a skin pass roll before introducing the steel sheet between topochrome rolls for guaranteeing the contact between the hemisphere of the TOPO(Trioctylphosphine Oxide) chromium rolls and the steel sheet. A skin pass mill for increasing the oil pockets of a steel sheet includes a grinding stand(30) having polishing rolls(32) for grinding the surface of a steel sheet(10) and a first skin pass stand(40) having first TOPO chromium rolls(42) for forming oil pockets in the steel sheet. A second skin pass stand(50) has second TOPO chromium rolls(52) for increasing the oil pockets in the steel sheet. The shape and distribution of the first and second TOPO chromium rolls are random.
