Embodiment 1

[0166] Embodiment 1 is a metal processing system that includes variable sized heat treatment equipment having an opening for receiving a metal strip moving at a strip speed in a direction of movement. The heat treatment apparatus includes a heating unit positionable adjacent to the metal strip on a first side of a separation plane intersecting the metal strip to increase the strip temperature of the first portion of the metal strip on the first side of the separation plane during the heat treatment temperature or higher than the heat treatment temperature; and a cooling unit, which may be positioned near the metal strip on the second side of the separation plane to maintain the second portion of the metal strip on the second side of the separation plane below the heat treatment temperature.

Embodiment 2

[0167] Embodiment 2 is the system of embodiment 1, wherein the separation plane is parallel to the metal strip, wherein the heating unit extends across the width of the metal strip proximate the first side of the separation plane, and wherein the cooling unit is on a second side proximate the separation plane. The side metal strips extend across the width.

Embodiment 3

[0168] Embodiment 3 is the system of embodiment 1, wherein the separation plane is parallel to the longitudinal axis of the metal strip and perpendicular to the top surface of the metal strip, wherein the thermal processing apparatus further comprises the metal strip positionable proximate to the first side of the separation plane and an additional heating unit opposite the metal strip from the heating unit; and an additional cooling unit positionable adjacent to the metal strip on the second side of the separation plane and opposite the cooling unit.

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 heattreatment, 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.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Patent Application 62 / 408,853, entitled "METAL SHEET WITH TAILORED PROPERTIES," filed October 17, 2016, which is hereby incorporated by reference in its entirety. technical field [0003] The present disclosure relates generally to metalworking, and more particularly to heat treating metal strip. Background technique [0004] Metal components are used for many purposes, such as structural supports for vehicles such as automobiles. Metal components may be formed from metal strip, for example by cutting the metal strip into individual blanks and deforming each blank into the desired part shape (eg by stretching). [0005] Certain components may require high strength, for example when used as structural supports. However, sometimes the metal must have sufficient elasticity or other desirable properties in order to properly form the components. Metals such as alumi...
