摘要： PURPOSE:To prevent the spread of vapor flow to the rear side of a strip and to permit satisfactory vapor deposition on one face of the strip by providing a pair of wedge-shaped baffle plates to a vacuum deposition treatment chamber in the transverse direction of the strip. CONSTITUTION:A pair of the baffle plates 3 made into the wedge shape having the angle sharper than 90 deg. at the section in the front end part are provided to the lower side of the strip S traveling in a vapor deposition treatment chamber 1 for depositing a vapor deposition material housed in a crucible 2 by evaporation onto the strip S. The baffle plates 3 are provided movably forward and backward in the transverse direction of the strip S. The vapor flow of the above-mentioned vapor deposition material is blocked by the baffle plates 3 and is prevented from spreading to the rear side of the strip S.

摘要： PURPOSE:To execute continuous vapor deposition without hindrances by providing plural crucibles contg. vapor deposition materials in a vapor deposition treatment chamber, preliminarily providing plural electron guns and changing over the electron guns to a continuously supplied belt-like material, thereby executing the vapor deposition. CONSTITUTION:The electron beam from the electron gun 3 is deflected by a deflecting magnetic field 7 to evaporate the vapor deposition material in the crucible 1 and to deposit said material by evaporation to the continuously fed belt-like material. The operation time of the electron gun 3 is counted during this time so as to exchange the electron gun when the integrated operation time attains the set time. On the other hand, the output of the electron gun is kept monitored at all times even within the set time and the electron gun is exchanged and the abnormality is displayed when the output drops below the prescribed set level. A gate valve 6 is opened to turn on the electron gun 4 and to start the vapor deposition from the crucible 2 via a deflecting magnetic field 8 when the operation time of the electron gun 3 attains the preset time. As a result, the electron gun is exchanged before the electron gun under use becomes unusable. The continuous vapor deposition treatment to the belt-like material S is thus executed without hindrances.

摘要： PURPOSE:To improve remarkably the rolling efficiency by arranging motor- driven horizontal mills and non-driven vertical mills in series and increasing the aspect ratio of a rolling stock at the inlet side of each horizontal toward the downstream of rolling. CONSTITUTION:The sectional view of a slab is shown by the figure 10, the sectional views of the rolling stock at the outlet sides of the 1st, 2nd, 3rd of motor-driven horizontal mills are shown by the figures 211, 212, 213 respectively, and the sectional views at the outlet sides of the 1st, 2nd, 3rd non-driven vertical mills are shown by figures 221, 222, 223 respectively. In such manner, the aspect ratio of the rolling stock at the inlet sides of horizontal mills that ia at the outlet sides of vertical mills is increased toward the downstream. In this way, the reduction rate of area of the non-driven vertical rolling is increased, and the rolling efficiency is remarkably improved.

摘要： PURPOSE:To carry out the tension-free rolling pass through the strands of both of the final stand and the fore-final stand, to improve the productivity, and to reduce the scatter of the product accuracy, by making the fore-final stand to be the reference stand. CONSTITUTION:In the finishing stands K1-K4 being arranged in series, the fore- final stand K2 is particularly made the reference stand for controlling the roll's r.p.m., and besides, the loopers 4, 4, are installed in two places, one between the final stand K1 and the fore-final stand K2, and another between the fore-final stand K2 and its upstream stand K3. By controlling the roll's r.p.m. of the final stand K1, the upstream stand K3 and its upstream stand K4, by means of the fore-final stand K2, the loop control is performed; hereby, the rolled material 3 is fed into the final stand K1 and the fore-final stand K2 under the tension-free condition, and the finish rolling pass is carried out.

摘要： PURPOSE:To simply enable the vapor deposition of different materials in layers or the vapor deposition of an alloy by dividing the vapor deposition chamber of a continuous vapor deposition apparatus for a strip-shaped material into plural chambers and by alternately projecting an electron beam from an electron gun on the chambers. CONSTITUTION:The vapor deposition chamber 1 of a continuous vapor deposition apparatus for a strip-shaped material is divided into plural chambers 3, 4 with a partition wall 2. Crucibles A, B contg. different materials (a), (b) to be vapor-deposited are placed in the chambers 3, 4. An electron beam 6 from an electron gun 5 is alternately projected on the materials (a), (b) to continuously vapor-deposit the different materials (a), (b) on a strip-shaped material S.

摘要： PURPOSE:To provide the titled vapor deposition treatment chamber which can make effective sealing between a vapor deposition chamber and vapor deposition treatment chamber even if there is a fluctuation in the wall thickness of a steel strip by proving plural pieces of sealing rolls in rolling contact with a vapor deposition guide roll for the steel strip delineating the vapor deposition treatment chamber in the peripheral direction of said roll to holders by spring energization. CONSTITUTION:The holders 17 are retreated by cylinders 10 to allow the steel strip to pass through the device at the time when the steel strip S passes through the device. The holders 17 are advanced to prescribed positions after the pass-through of the steel strip S and the sealing rolls 16 are pressed to the steel strip S wound around the vapor deposition guide roll 11. The roll 16 moves by following up to the fluctuation of the wall thickness even if there is the fluctuation in the wall thickness of the steel strip at the time of the vapor deposition; therefore, the sealing between the vapor deposition chamber B and the treatment chamber 14 is executed without hindering the operation. Since the vapor flow from a vapor deposition material from a crucible 2 constitutes viscous flow particularly at the time of the high-speed vapor deposition, a so-called labyrinth effect is generated by plural pieces of the rolls 16 and the sealability is further improved.
