Abstract

PURPOSE:To manufacture a cold rolled bright steel sheet almost free from surface flaws by a dry system, by including a roll cleaning mechanism, which uses a temper rolling mill oil, in a dry system of temper rolling process. CONSTITUTION:The temper rolling mill oil 10, applied to the outlet side outer surface of a backup roll 2 of a cold temper rolling mill, is carried with the rotation of the backup roll 2 in the arrowed direction and forms an oil puddle at the contacting part (a) of the backup roll 2 and a work roll 1. Thus puddling temper rolling mill oil removes foreign matters, dirty substances, etc., from the surface of the work roll 1 whose surface is thereby made clean. A part of the temper rolling mill oil adheres to the surface of the work roll 1 and goes together with the rotation of the work roll 1; however, this oil is blown off by jetting compressed air from a nozzle 4 at the feed-in side, and at the same time, a remaining oil is completely removed away by a brush 5 having a sucking function. By the present method, a rolled steel sheet with excellently improved surface roughness and defectless surface area percentage is manufactured.
