Patent JP-S5662923-A (JP)
Title: Production large-diameter heat-treated steel pipe
Inventor: OOTSUBO HIROSHI
IPC: B21C37/06
Filed: 1979-10-29
Abstract: PURPOSE:To make possible the production of a steel pipe which has a uniform outside diameter over the entire region of its longitudinal direction by beforehand making the rate of expansion in the pipe end part smaller than the rate of expansion in the pipe central part at the stage of pipe expansion at the time of heat treating a large-diameter welded pipe through induction heating. CONSTITUTION:A steel pipe 1 having been formed to a pipe shape and seam-welded is mechanically expanded to about 1.0-1.5% of the pipe diameter by a mechanical expander 2, after which it is transferred to a hardening process 3 where it is passed through the inside of an induction heating coil 4, whereby it is heated up to maximum 950 deg.C. Next, the steel pipe 1 is cooled from the inside and outside of the pipe by the water from nozzles 7, whereby it is contracted and hardened, after which it is subjected to tempering. In this case, the outside diameter of the expanded part from the front end of the pipe up to about 1m is beforehand made smaller by about 0.65% than the expanded outside diameter of the central part of the pipe. In this state, the pipe is subjected to hardening and tempering, and this causes the outside diameter of the pipe end parts to become larger than that of the central part without receiving any thermal stress from the front part. As a result, it is offset by the difference in outside diameter at the pipe expanding, and the entire part of the steel pipe assumes a uniform outside diameter.

Filed: 1999-05-20
Abstract: PROBLEM TO BE SOLVED: To manufacture a package with electrodes exposed at the bottom at a low cost, without etching, by using a stripping method as a means for removing a substrate from a resin package, rather than an etching method. SOLUTION: After forming a package 10, a metal film 14 and a lead frame 13 are removed from the package 10, and the metal film 14 is stripped off the package, together with the lead frame 13.
