Abstract

PURPOSE: To remove scales from the surface of a steel strip at relatively low cost by using a grinding roll made by forming emery cloth coated with grain into a roll and grinding the surface of the steel strip after hot rolling and thereby omitting pickling process.
CONSTITUTION: A steel strip 7 after annealing is sent to a grinding roll 6 through a pinch roll 3. If necessary, it is further sent to the second grinding roll 6' to grind the surface and coiled by a coiler 3 through a pinch roll 3'. In this case, the rolls 6, 6' are made by laminating many cloths of discoid shape prepared by coating alumina grain on a sheet of cloth and forming it into a roll. Breaker rolls 4, 4', 4" can be arranged between the roll 3 and roll 6, between rolls 6, 6' and between the roll 6' and roll 3', respectively. The rolls 4W4" give necessary tension to the steel strip 7 between rolls 4W4" and billy rolls 5, 5'. The rolls 5, 5' are placed opposite to the roll 6, 6' with the steel strip 7 between and press the steel strip against the rolls 6, 6'.
