摘要： PURPOSE:To obtain the smooth and uniform surface of a hot-rolled article made of titanium or titanium alloy by projecting the high-pressure liquid mixed with polishing material and pickling the workpiece with the mixed aqueous solution of nitric acid and hydroluoric acid. CONSTITUTION:After a hot-rolled titanium hot coil is annealed and pickling- treated, said hot coil is polished to form the state shown in (a) by a belt grinder having a grain particle size of #80, and the state shown by (b) is formed by projecting the high-pressure liquid mixed with the polishing material having a polishing-material mixing rate of 55vol% with a projection pressure of 110kg/ cm , and further the state shown by (c) is formed by pickling said hot coil with the mixed aqueous solution consisting of 200gr/l nitric acid and 30gr/l hydrofluoric acid at a temperature at 25 deg.C, under a spraying pressure of 1kg/cm , and for a spray time of 30sec. Therefore, crack is not generated on the hot rolled article thus obtained even after bending work, and the surface is smooth and uniform, and unevenness is not formed in the grinding trace since the worked surface layer due to the belt grinder and the projection of polishing material is removed through spray pickling.

摘要： PURPOSE:To reduce the development of spotting contamination on surface of a steel strip after annealing by arranging flowing passage of atmospheric gas at out of a furnace for again supplying the atmospheric gas once sucked to out of the furnace from heating zone or cooling zone into an introducing part of the furnace in the continuous bright annealing for stainless steel strip. CONSTITUTION:By again supplying the atmosphere gas into the introducing part 1 of furnace after once sucking the atmospheric gas to out of the furnace from the heating zone 2 or the cooling zone 3 by using booster 10 for atmospheric gas, the flowing direction 8 of atmospheric gas at inlet part of the heating zone 2 is made to the same direction as advancing direction 9 of the stainless steel strip 7 to be annealed to execute the continuous bright annealing to the stainless steel strip 7. By this method, the flowing direction 8 of atmospheric gas at the inlet part of heating zone 2 can be made to the same direction as the advancing direction 9 of stainless steel strip 7 to be annealed. Therefore, sticking of while powder developed in the heating zone 2 onto the surface of low temp. steel strip 7 before annealing at the introducing part 1 of furnace by being directly carried to the direction of introducing part 1 in the furnace, can be prevented.

摘要： PROBLEM TO BE SOLVED: To naturally fall a cut sheet into a bucket even when it is short in a direct drive shear which is provided on a strip process line and with which the strip is cut into a prescribed length and the cut sheet such as a weld zone and sampled material is cut out of the strip. SOLUTION: An upper tapered face 13 and a lower tapered face 14 are provided on the lower cutting edge 7 of the direct drive shear 4 which is provided on the strip processing line and an opening/closing table 17 and a tilting table 21 are provided in a gate 15. Because the upper tapered face 13 is provided on the lower cutting edge 7, the horizontal face is narrow in the width. Consequently, even when the cut sheet S on the lower cutting edge is short, it is naturally fallen by losing its balance and slipped down on the tilting table 21. In the case the cut sheet S is housed in the bucket, the gate 15 is released by lifting the closing table 17 and tilting table 21 with a pneumatic cylinder 19 for opening and closing motion.

摘要： PURPOSE:To remove stuck oil on a strip before being coiled after rolling as much as possible. CONSTITUTION:First wiping rolls 3a, 3b are provided opposite to each other so as to pass the strip 1 after rolling through them while holding it between them, second wiping rolls 5a, 5b are arranged offsetting each other so as to bend the strip in the surface and back directions and air blowing nozzles 7a, 7b through which air is blown toward the edge parts of each surface of the strip are provided. Stuck oil on the surface and back faces of the strip 1 is roughly removed with the first wiping rolls 3a, 3b, stuck oil which remains in edge parts of each surface of the strip without being removed is removed with the second wiping rolls 5a, 5b and oil which remains in the edge parts is removed by blowing off with air. So stuck oil is more surely removed.

摘要： PURPOSE:To make the device compact and to improve the efficiency in space. CONSTITUTION:A coil placement base 2 on which various kinds of insert paper coils 1 can be placed sideways is arranged in plural numbers in parallel; the various kinds of insert paper coils 1 are stored by classifying in different widths; and the coils are individually transferred to the end of exit for each corresponding coil placement base and by a coil transporting means. Also, in order to turn the insert paper coils 1 and transfer them to the end of exit 2b, the coil placement base 2 is inclined; and simultaneously, a movable stopper and the driving cylinder are provided by which the insert paper coils are individually and selectively received held, and selectively released and which is capable of transferring the insert paper coils individually. B turning the insert paper coils while transferring, the insert paper transporting device can be made compact. Moreover, by placing the insert paper coils so as to be able to turn them in the direction of tightening, a loosening at the time of transferring is prevented.

摘要： PURPOSE:To prevent wrinkles from occurring on a coiling and nucoiling machine by constituting a strip passing guide device of a deflector roll a sledding guide and its oscillating cylinder CONSTITUTION:The strip passing guide device of the coiling and uncoiling machine is constituted of the deflector roll 3 provided between a cold rolling mill and a tension reel 12, a sledding guide plate 4 which is provided with a guide surface inducing the tip of a steel strip and one end part of which is mounted on the shaft of the deflector roll 3, and the oscillating cylinder 5. A cylinder rod is connected with one end of the sledding guide plate 4 and the device is turned by the oscillating cylinder 5 round the fulcrum of the deflector roll 3. The sledding guide plate 4 reduces the turning support interval of the steel strip and a press roll 9 for pressing a coiling point is fixed through a link arm 10 so that it can oscillate. Consequently, the tip part of the steel strip can be induced surely to a rolling line and moreover coiled wrinkles occurring in rolling can be prevented.
