PROCESS AND APPARATUS FOR COOLING A COLD ROLLED STEEL STRIP

摘要

A cold rolled steel strip having an elevated temperature is continuously cooled to a desired temperature at a desired cooling rate by a process comprising moving the cold rolled steel strip along at least one vertical cooling path, and; bringing a plurality of streams each consisting of a mixture of a cooling gas and a cooling liquid into contact with each surface of the steel strip, each mixture stream being prepared by jetting the cooling gas and liquid independently from others in directions intersecting each other before the vertical path of the steel strip.
