Abstract
A method and system solution heat treat, at an elevated first temperature, a coil of aluminum alloy sheet to form a heat-treated coil and while at least a portion of the heat-treated coil is being solution heat treated, uncoil a heat-treated portion of the aluminum alloy sheet from the heat-treated coil and continuously quenching the uncoiled heat-treated portion to form a quenched sheet.
Claims26
A method of manufacturing aluminum alloy sheet comprising:
- heating, in a heat-treatment furnace and at an elevated first temperature, a coil of aluminum alloy sheet to form a heat-treated coil;
- while at least a portion of the heat-treated coil remains in the heat-treatment furnace:
- uncoiling a heat-treated portion of the aluminum alloy sheet from the heat-treated coil;
- passing the uncoiled heat-treated portion of the aluminum alloy sheet through an outlet of the heat-treatment furnace;
- and
- continuously quenching, by a quenching unit, the uncoiled heat-treated portion to form a quenched sheet.
3 more elements
A system, comprising:
- a heat-treatment furnace comprising a housing enclosing a volume dimensioned to receive a coil formed from an aluminum alloy sheet, the housing comprising an inlet port dimensioned to receive the coil into the furnace room and an outlet port, separate from the inlet port, for outputting a heat-treated portion of the aluminum alloy sheet uncoiled from the heat-treated coil, the inlet port having a larger opening size than the outlet port;
- and
- a quenching unit comprising one or more quenching devices and sheet inlet and outlet ports to receive the heat-treated portion and output a quenched sheet, respectively, wherein the sheet inlet port of the quenching unit is spatially proximal to the outlet port of the heat-treatment furnace and wherein the one or more quenching devices are positioned within the quenching unit to quench the heat-treated portion to form the quenched sheet.
A method comprising:
- solution heat treating, at an elevated first temperature, a coil of aluminum alloy sheet to form a heat-treated coil;
- while at least a portion of the heat-treated coil is being solution heat treated:
- uncoiling a heat-treated portion of the aluminum alloy sheet from the heat-treated coil;
- and
- continuously quenching the uncoiled heat-treated portion to form a quenched sheet.
