Abstract

PURPOSE:To decrease the cracks generating on the hearth rolls, by sending the cold rolled thin steel belt into the heating furnace after having preheated the above steel belt by sucking the combustion gas of the plenum chamber and blowing the jet stream of the gas of high temperature from the outlet side of the blower on the cold material of the above steel belt.
