ABSTRACT:
A process of treating metal strips using a linear electric motor with spaced apart motor elements comprises directing the metal strips into the space between the motor elements and operating the motor to produce a travelling wave and advancing the strip between the motor parts without contact thereof at a velocity greatly reduced with respect to the velocity of the linear electric motor wave so as to produce a slippage between the wave and the strip and to effect the heating of the strip as it is advanced. The apparatus includes a linear electric motor including a first motor unit spaced away from a second motor unit in the form of a linear motor or return bar so as to form a gap therebetween through which the metal strip is advanced. The apparatus includes means for feeding the strip through straightening rolls and cropping shears, S-rollers and coiling and uncoiling reels.
