摘要： PURPOSE:To make the capacity of slow cooling adjustable and to improve the accuracy of coiling temp. by movably arranging an impeller type spraying device right under an upper laminar nozzle. CONSTITUTION:By oerating an operating rod 3, the impeller 1 is moved in the position shown by chain line. The laminar flow of cooling water which flows out of the nozzle 6a of a laminar pipe 6 is broken with the impeller 1 and sprayed cooling function is lowered, so a strip 8 which is transported on table rollers 7 is slowly cooled. On the other hand, in the case of executing ordinary laminar cooling, by returning the operating rod 3 and situating the impeller 1 in the position shown by continuos line, the impeller 1 is deviated from the laminar flow from the laminar pipe 6 and cooling by the laminar flow is possible. The tip nozzle of a compressed air line 5 is made so as to touch the vanes of the impeller 1 and, in this way, by arbitrarily adjusting the number of revolution of the impeller 1 by changing the pressure and flow rate of compressed air and changing the spray range, the cooling function is adjusted.

摘要： PURPOSE:To enable suction of a large quantity of combustion exhaust gas in a heating furnace and thereby to enable attainment of low NOx by a method wherein the mixture of fuel and vapor is jetted from nozzles to venturi tubes of a burner part in a heat storage type burner. CONSTITUTION:A heat storage type burner 1 is constructed to be in an exhaust gas recirculation system and supply of air for combustion from an air intake 3 and exhaust of a combustion exhaust gas are conducted through a heat storage body 2. The combustion exhaust gas in a heating furnace is sucked through recirculation ducts 6 and mixed in a burner part. In this case, venturi tubes 5 are attached to the burner part and nozzles 4 jetting the mixture of fuel and vapor to the venturi tubes 5 are disposed in this part. Moreover, the combustion exhaust gas in the heating furnace is sucked and made a driving source of the venturi tubes 5. In other words, a negative pressure is brought forth in the venturi tubes 5 with jetting from the nozzles 4 and thereby the combustion exhaust gas in the heating furnace is sucked through the exhaust gas recirculation ducts 6. According to this constitution, reduction of NOx can be facilitated.

摘要： PURPOSE:To facilitate the mounting of a knife by lightly holding the circular knife positioned on one side of a shaft at a low pressure, so as to be used as a reference for the positioning of another circular knife on the other side of the shaft, at a low pressure, and by holding the circular knives on both sides of the shaft at a high pressure. CONSTITUTION:Circular knives are inserted externally, while valves 31, 32 are closed and inner pressure is not applied to arbor shafts 10, 20. The circular knife of the upper arbor shaft 10 is slid in a shaft direction, and is positioned as predetermined, while the valve 31 is opened, and a low pressure is applied to the outer tube shaft of the upper arbor shaft 10 by a low pressure liquid pressure circuit 33, so as to hold the circular knife. The circular knife on the lower arbor shaft 20 is positioned on the lower arbor shaft 20, by adjusting a gap by using the circular knife on the upper arbor shaft 10 as a reference, while the valve 32 is opened, and the circular knife on the lower arbor shaft 20 is held at a predetermined position. A valve 34 is then opened, and a high pressure is applied to both of the arbor shafts 10, 20 by a high oil pressure circuit 35, so as to sufficiently widen the diameter of the outer tube shaft, whereby the circular knives can be held tight even at the time of slit work.

摘要： PURPOSE:To make automatic cutter-set work for a slitter performable by installing a storer housing a lot of spacers and cutters in close proximity to a slitter arbor shaft, and a conveyor whose tip makes these spacers and cutters detachable and being self-propellable, respectively. CONSTITUTION:In this device, there are provided with a storer 1 housing a spacer-cutter 12, and a conveyor 2 equipped with an automatic setter 4 for the spacer-cutter 12, in parallel with a slitter stand 3 and, between both, being self-propellable parallelly with both and, what is more, being rotable at 180 degrees on the upper part. With this formation, the whole arrangement of a cutter-set is determined, and when the information is given to the device, the automatic setter 4 is moved to a position where the spacer or the cutter of each object number is possible to be taken out at the storer 1, and after the spacer or the cutter is taken out of this storer 1, the conveyor 2 moves the spacer or the cutter to a setting position of an arbor shaft 6 of the slitter stand 3 by means of the travel rotation control. With this constitution, slitter cutter-set work can be does automatically.

摘要： PURPOSE:To attain automatic quantitative segmenting and assured injection independently of the state of a sample by spooning up the powder sample by a pipe-shape sampling spoon having a spoon-like opening part and a shock core and uniformalizing and dropping the excessive sample. CONSTITUTION:The sampling spoon 4 is set up on a spoon setting board 5 to spoon up the powder 1 in a sample tank 2 by the opening part 4' of the spoon 4 and uniformalize and drop the excessive powder by an evening device 3. When the opening part 4' is carried to the position of a container 6, the spoon 4 is inclined around the opening part 4', a steel ball B drops along the pipe in wall of the spoon 4 and collides with the shock core C and the whole sample 1 in the spoon 4 is dropped into the container 6 by the shock. THus, the quantitative segmenting of trace quantity of the sample 1 is executed by a general robot hand on the basis of a fixed sampling operation independently of the status of the sample 1 and the excessive sample 1 can be automatically dropped into the container 6.

摘要： PURPOSE:To obtain the effect equivalent to or better than that by V-H configuration of high rigidity mills by incroporating >=1 unit of 4-roll mills to a continuous rolling mill group for rolling of steel bars. CONSTITUTION:Square calibers 6, 6 are used in the 2Hi high rigidity mill of the i-1 stand, round calibers 7, 7, 7, 7 are used in the 4-roll mill 10 of the (i) stand and further 2Hi mills having elliptical calibers 8 are used in the i+1 stand. Steel bars are rolled between the stands before and after the 4-roll mills under tensionless control. Then, the variance in the sizes before the i-1 stand is condensed to the variance of the size H by the 2Hi high rigidity mill of the calibers 6, 6 and the size B hardly changes. The sizes of the height (h) and the width (b) are made virtually constant by the 4-roll mill 10.
