Title: Production of copper or copper alloy tube
Inventor: TSUCHIYA AKINORI
IPC: C22F1/00
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To prevent sticking of a copper or a copper alloy tube stock and to smoothly uncoil it from the coiled state by coating the surface of the copper or copper alloy tube stock with a poly α olefin and the oligomer thereof to a specified film thickness, thereafter coiling it into the coiled shape and executing annealing in a reducing atmosphere. SOLUTION: The surface of a copper or copper alloy tube stock obtd. by subjecting a tube stock to forging, extruding, rolling and reducing is coated with poly α olefin and the oligomer thereof to a film thickness of 0.01 to 3 μm by being diluted with the other solvent or lubricant according to request. The tube stock after the coating is coiled to a coiled state, which is annealed, e.g. at a temp. of >=500 deg.C in a reducing atmosphere to obtain a copper or copper alloy tube. In this annealing stage, poly α olefin and the oligomer thereof are easy to remain on the surface of the copper tube even after the heat treatment and make the metal contact time between the copper tubes short, and make the diffusion of copper insufficient.  In this way, the sticking phenomenon of the copper tubes is prevented to eliminate the possibility of stopping the process by trouble caused by the sticking and to reduce the loss of the copper or copper alloy tube.

Abstract: PURPOSE: To prevent the abrupt discharge of heat at the time of heat treating raw refuse by heating the refuse by a heater to generate steam, and radiating the generated steam to the water in a water tank via a condensing pipe to condense it. CONSTITUTION: The start button of an operating unit 34 is pushed to start drying. A heater 7, a deodorizing heater in a separator 12 and a cooling fan are turned on by a start signal. An agitating motor 5 is rotated at the suitable time to raise the drying efficiency. Further, the steam generated from raw refuse is radiated to the cooling water in a water tank 31 via a condensing pipe 11 to be condensed, and discharged as condensed water of about 80 deg.C. The odor which is not condensed is decomposed by a deodorizer in a separator 12 and drain from a drain pipe 14.
