Patent number: 4676999Abstract: For vacuum deposition plating steel strip, a vacuum deposition plating apparatus is used including an inlet-side vacuum sealing device provided in front of a vacuum deposition plating chamber, with an inlet-side inactive gas replacement chamber provided between the inlet-side vacuum sealing device and an annealing furnace. An outlet-side vacuum sealing device is provided at the rear of the vacuum deposition plating chamber, with an outlet-side inactive gas replacement chamber provided between the outlet-side vacuum sealing device and the atmosphere. An inactive gas circulating/purifying device circulates an inactive gas from vacuum chambers of both the vacuum sealing devices to atmospheric pressure chambers of both the vacuum sealing devices and removes water, oil and oxygen from the inactive gas. Oxygen and hydrogen in the inactive gas are regulated to provide 60 ppm or less of oxygen and 0.2 to 2.0% of hydrogen, and also to regulate the dew point of the inactive gas to -50.degree. C. or less.Type: GrantFiled: September 11, 1985Date of Patent: June 30, 1987Assignees: Mitsubishi Jukogyo Kabushiki Kaisha, Nisshin Steel Co., Ltd.Inventors: Heizaburo Furukawa, Kanji Wake, Yoshio Shimozato, Kenichi Yanagi, Mitsuo Katoh, Tetsuyoshi Wada, Norio Tsukiji, Takuya Aiko, Toshiharu Kittaka, Yasuji Nakanishi

Patent number: 4649860Abstract: A vacuum evaporation equipment for continuous vacuum evaporation of a metal onto a band or strip of product including at least one vacuum sealing station, provision of ducts that are disposed surrounding the band product and extending from the point of vapor deposition where the band product is subjected to a vacuum evaporation process an a chamber held at a reduced pressure or vacuum state to the extent that substantially no reevaporation of once deposited metal is effectively prevented from occurring. The ducts are adapted to be heated to a temperature substantially higher than the temperature of the steel band product. In addition, there is provided at least one vacuum sealing station with rolls rotatably mounted in the interior of a casing and a complementary sealing bar mounted in a complementary engagement relationship with the rolls having a close gap therebetween.Type: GrantFiled: March 19, 1985Date of Patent: March 17, 1987Assignees: Mitsubishi Jukogyo Kabushiki Kaisha, Nisshin Steel Co., Ltd.Inventors: Heisaburo Furukawa, Kanji Wake, Yoshio Shimozato, Kenichi Yanagi, Mitsuo Kato, Tetsuyoshi Wada, Norio Tsukiji, Takuya Aiko, Toshiharu Kittaka, Yasuji Nakanishi

Patent number: 4643131Abstract: Disclosed is a combined continuous plating apparatus for hot-dip plating and vacuum deposition plating characterized in that the outlet of the gas reduction annealing furnace of a conventional continuous hot-dip plating apparatus and the inlet of the seal roll chamber of a known continuous vacuum deposition plating apparatus are connected through a pressurized chamber in order to prevent invasion of hydrogen-containing reduction gas into the vacuum deposition chamber, whereby is prevented the possibility of the hydrogen-containing gas causing an explosion should air leak into the vacuum deposition chamber.Type: GrantFiled: September 20, 1985Date of Patent: February 17, 1987Assignees: Nisshin Steel Company, Ltd., Mitsubishi Jukogyo Kabushiki KaishaInventors: Shozo Umeda, Norio Tsukiji, Takuya Aiko, Toshiharu Kittaka, Heizaburo Furukawa, Kanji Wake, Yoshio Shimozato, Kenichi Yanagi, Mitsuo Kato, Tetsuyoshi Wada

Patent number: 4552092Abstract: A vacuum vapor deposition system including a high-vacuum vapor deposition chamber provided with a rotary cell around which band steel is wound as it is passed through the chamber. A crucible for molten metal has a hood for guiding vapor of said metal to a vapor deposition port opposed to the rotary cell, and arcuate covers connected to the hood at the entrance and exit positions of the band steel. The vapor deposition port is spaced slightly from the rotary cell so that the covers will not come into contact with the band steel. A heater is provided for heating the surface of the rotary cell up to a temperature equal to or higher than a reevaporation temperature of the metal under a vapor pressure of the vapor of the metal in the proximity of the rotary cell so that the metal will not be deposited onto the opposite end portions of the rotary cell which are not covered by the band steel.Type: GrantFiled: September 19, 1984Date of Patent: November 12, 1985Assignees: Mitsubishi Jukogyo Kabushiki Kaisha, Nisshin Steel Co., Ltd.Inventors: Kenichi Yanagi, Toshio Taguchi, Tetsuyoshi Wada, Heisaburo Furukawa, Kanji Wake
