Abstract
Moving metal strips can be heat treated with any number or combination of dimensionally variable tempers across widths, lengths, or thicknesses of a metal strip. To provide dimensionally variable heat treatment, an apparatus can include one or more heating units suitable to increase the temperature of a metal strip moving proximate the apparatus to a heat treatment temperature. The apparatus can also include one or more cooling units positioned near the heating units to absorb heat and cool the metal strip to minimize the amount of heat transferred from a first region of the metal strip that is to be treated to a second region of the metal strip that is not to be treated.
