Title: Hot rolling method for titanium or titanium alloy
Inventor: KIDA TAKAYUKI
IPC: C22F1/18
Filed: 1993-10-04
Abstract: PURPOSE:To prevent the generation of scabs at the time of cold rolling executed after hot rolling by growing qui-axed crystals on the surface layer, regulating the thickness of a high concn. oxidizing layer to a uniform one and executing the hot rolling. CONSTITUTION:In the final stage of blooming or in the initial stage of hot rolling, recrystallized grains are grown in an alpha phase single temp. region to form the crystals from the surface of the material to a depth of >=60mum into qui-axed ones, and after that, it is heated in the temp. range of an alpha phase single region or in an (alpha+beta) two phase region in an atmosphere contg. oxygen and is subjected to hot rolling. In this way, the formation of a locally deep high concn. oxygen layer is checked, and a uniform oxidizing layer can be obtd. Thus, the perfect removal of the oxidizing layer in a descaling stage before cold rolling is made possible, and the generation of scabs at the time of cold rolling caused by the local remaining of a high oxygen concentrated layer can be prevented.

Filed: 1984-11-27
Abstract: PURPOSE:To make such a highly accurate positioning as being below 0.1mum performable in a stable manner without producing overload in a driving mechanism, by checking a vibration to be generated in time of a sudden table stop in a way of making full use of damping action inherent in an overcurrent. CONSTITUTION:A guide mechanism 4 is installed on a base plate 1 and provided with a table 2, while it pivotally supports this table 2 free of slide motion in an arrow 3 direction. And, a damping mechanism 6 checks a vibration to be produced in time of an end of travel in the table 2 by a driving mechanism 5. In addition, a control part outputs a control signal to the driving mechanism 5 and performs the positioning of the table. Therefore, since damping action inherent in an overcurrent is utilized, the vibration generated when the table 2 is suddenly stopped are almost nearly checked. In addition, since the table 2 and a magnet 23 both are of noncontact with the guide mechanism 4, no friction occurs there so that in cooperation with this fact, the positioning of the table 2 takes place at high speed.
