Patent number: 5666846Abstract: An apparatus and method for manufacturing seamless tubes from hollow billets that will not contain metal oxide, which may be introduced into the extruded metal tube from an oxide layer formed on the inner surface of the hollow billets, so as to improve the quality of the extruded product and extend the service life of the extrusion piercer rod. A de-oxide latch, which has a substantially circular disk shape and is dimensioned such that it is slightly larger than the inner diameter of the hollow billet, is placed in front of the piercer rod so as to remove the metal oxide layer formed on the inner surface of the hollow billet through an upsetting shearing force ahead of the normal stress generated by the forward movement of the extrusion stem. The extrusion apparatus also utilizes a screw and pierce doughnut combination to securely affix the piercer rod to the stem and to effectuate the extrusion of the hollow billet through an extrusion die to form seamless tubes.Type: GrantFiled: July 9, 1996Date of Patent: September 16, 1997Assignee: Industrial Technology Research InstituteInventors: Chin-Fu Chen, Wen-Hwa Lu, Shan-Chang Chueh

Patent number: 5632319Abstract: A process for making high-quality foamed aluminum articles is disclosed. This process comprises the step of: (a) placing a raw aluminum feedstock into a mold, the raw aluminum feed stock contains at least 50 wt % spent (i.e., recycled) aluminum and does not contain any extraneous viscosity enhancing agent such as metallic calcuim or magnesium; (b) heating the mold so as to melt the raw aluminum feedstock to form a liquid aluminum mass; (c) stirring the liquid aluminum mass in open air to increase its viscosity by a factor of at least about 1.3 to 1.8; (d) adding a foaming agent into the liquid aluminum mass; (e) continuing stirring the liquid aluminum mass containing the foaming agent so as to generate and uniformly distribute gas bubbles inside said liquid aluminum mass; and (f) cooling and solidifying the liquid aluminum mass to room temperature so as to form the foamed aluminum article. In a preferred embodiment, recycled foamed aluminum materials are used as the raw aluminum feedstock.Type: GrantFiled: October 4, 1995Date of Patent: May 27, 1997Assignee: Industrial Technology Research InstituteInventors: Chin-Chen Yang, Shan-Chang Chueh, Kou-Chang Su, Ting-Huey Chiou
