  • Continuous annealing apparatus
    Patent number: 4575053
    Abstract: A continuous annealing apparatus for metal strips comprises cylindrical rolls each arranged at a location immediately before the metal strip passes about a hearth roll in a high temperature heat-treatment region of the apparatus. An axis of the cylindrical roll is finely tilted relative to the hearth roll within 0.15 degree in directions compensating for shifted distances of the metal strip on the hearth roll in response to every 50 mm shift of the strip, thereby preventing meandering and buckling of the metal strip caused by the hearth rolls.
