A method of manufacturing aluminum alloy sheet

Abstract: A method for manufacturing aluminum sheet stock which includes hot rolling an aluminum alloy sheet stock, annealing and solution heat treating it without substantial intermediate cooling and rapid quenching.

A method of manufacturing can body sheet

Abstract: A method for manufacturing aluminum alloy can body stock including a continuous, in-line sequence of hot rolling, annealing and solution heat treating without intermediate cooling and rapid quenching.

Method of manufacturing can body sheet using two sequences of continuous, in-line operations

Abstract: A method for manufacturing aluminum alloy can body stock including two sequences of continuous, in-line operations. The first sequence includes the continuous, in-line steps of hot rolling, coiling, coil self-annealing and the second sequence includes the continuous, in-line steps of uncoiling, quenching without intermediate cooling, cold rolling and coiling.

Method and apparatus for twin belt casting of strip

Abstract: An apparatus and method for strip casting of metals on at least one endless belt whereby the belt is cooled when it is not in contact with molten metal deposited on its surface.

Liquid edge bead removal device

Abstract: A device and a method are provided for the removal of liquid coolant or lubricant edge beads from the side marginal edges of a moving web, such as metal sheet or strip. The device consists of two or more pairs of manifolds, wherein the individual manifolds of each pair are positioned above and below the main surfaces of the moving web and the manifolds also extend beyond the side edges of the web. The manifolds are arranged at an angle to the side marginal edges of the web and compressed gas is introduced to the manifolds. The introduction of the compressed gas, such as air, through the manifolds provides vertical curtains of compressed gas parts of which impinge on the surfaces of the web and thus create turbulence at the side marginal edge portions where the liquid edge bead is located. Due to the turbulence created at the side marginal edge areas of the moving web effective removal of the liquid edge bead can be accomplished.

Contained quench system for controlled cooling of continuous web

Abstract: A method and apparatus for continuously cooling a moving web while simultaneously removing the cooling fluid from the web in which a stream of quenching fluid (18) is applied transversely across the web (12) to cool it and a fluid containment gas is positioned on either side of the quenching fluid to direct a containment fluid (50,51) toward the quenching fluid to establish a continuous containment fluid curtain stream to prevent passage of the quenching fluid beyond the point of which the containment fluid is introduced.

Corrosion-resistant aluminum alloy brazing composite

Abstract: A novel aluminum alloy brazing composition is provided consisting of a core alloy consisting of a core alloy and a cladding on at least one side of the core alloy and wherein the core alloy consists essentially of manganese from about 0.8 to about 1.5%, silicon from about 0.45 to about 0.75%, titanium from about 0.03 to about 0.1%, a combined magnesium, copper and zinc content not in excess of about 0.15%, an iron content not in excess of about 0.3%, the total quantity of other impurities not exceeding about 0.15%, balance aluminum; and wherein the cladding consists of an AA 4XXX series aluminum alloy. The aluminum alloy brazing composition can be employed in the brazing of evaporators such as plate-fin evaporators utilized in the automotive field.
