摘要： PURPOSE:To prevent hot dipping from being made uneven owing to the deposition of flying metal by forming the inside and outside of the spray hole of each wiping spray nozzle with carbon or a molten metal deposition preventive based on carbon. CONSTITUTION:In the hot dipping apparatus, coats 26 of carbon or a molten metal deposition preventive based on carbon are formed on inside and outside 26 of spray hole 22 of each wiping spray nozzle 18 for removing excess metal. Thus, flying metal 30 produced when excess metal is wiped by spraying a heated gas is prevented from depositing on the surface of each nozzle 18. In addition, monitoring work, deposited metal removing work and other work by a worker under a hot unfavorable atmosphere with noise are made unnecessary.

摘要： PURPOSE:To enable the zinc ingot to be changed into a melting vessel without interfering with a snout and to reduce the cost for installation by a method wherein a hanger is installed at a position horizontally separated from its lifting device by a specified distance. CONSTITUTION:The zinc ingot 2 is lifted by a hanger 13 from belt conveyor which is not shown, is moved by a movable truck 6, and is charged into a zinc melting vessel 3. In this equipment, the leading edge of the hanger 13 is located at a specified distance from the opening edge of the vessel 3 toward its center. The hanger 13 is designed to rotate via cylinder 12 and link lever 10, and to hold and release the ingot 2 by the operation of a cylinder 15. The structure allows the hanger 13 to operate without interfering with the snout 17 located and enables an ingot 2 to be charged in.

摘要： PURPOSE:To increase the strength against oscillation of a roll support frame for synchronizing rolls effectively, by extending the parts including the opposited positions of furnace shells for the purpose of supporting and fixing said frame inward with respect to an inside furnace side. CONSTITUTION:Brackets 18, 18 extending mutually inward with respect to an inside furnace 11 side are provided in the opposed parts of furnace shells 13 including the positions for supporting and fixing a roll support frame 15, and receiving seats 16, 16 are provided respectively on the brackets 18, 18. The results are that the supporting and fixing parts of the frame 15 are supported and fixed between the seats 16 and 16 in the upper parts of the refractory layer 12 nearer the inner side than the inside surfaces of the furnace shells 13, 13. Therefore, the distance between the supporting and fixing positions is reduced to a distance L2 as compared to the distance L1 between the dotted line parts in the prior art. While the strength against oscillation of the frame 15 increases, the shape and weight of the frame 15 do not increase, and rather the size and weight are reduced.

摘要： PURPOSE:To enable a gas nozzle, etc. to be repaired rapidly and easily by extending a frame to the side of a hot dipping bath and attaching a gas feed pipe provided with the gas nozzle to the free end of the frame so that the pipe can be detached and turned. CONSTITUTION:Header pipe 3 provided with wiping nozzle 1 and nozzle header 2 is detachably attached to the free end of frame 4 extending to the side of hot dipping bath 31 by means of cap 27. The spray angle of nozzle 1 is adjusted with hundle 24. When clogged or damaged nozzle 1 is repaired, cap 27 connecting with frame 4 is moved upward while turning on pin 28 by removing cotter 29, and nozzle 1 and pipe 3 alone are separately detached and repaired or exchanged. Thus, the cutting, rewelding and other working of steel strip 13 are made unnecessary, and nozzle 1 can be repaired rapidly and safely.

摘要： PURPOSE:To prevent scratches in cleaning of the titled spray nozzle by a method wherein a sulfonitriding layer ia formed on the outer surface of the spray nozzle so that sprayed molten metal is hardly deposited or can be easily peeled off if deposited. CONSTITUTION:The spray nozzle 4 has spray opening 3 that faces the surface of a lated strip 2 moving upward from molten metal 1. The sulfonitriding layer 8 of about 0.2-0.3mm. depth is formed on the outer surface of the spray nozzle 4 and the inner surface of the spray opening 3. This prevents small metal particles 7 sprayed around the wiping area from depositing on the leading edge of the spray nozzle and on the inner surface of the spray opening 3. The sulfonitiding layer 8 has a high hardness and an excellent lubricant property and is easy to peel off deposits in cleaning and thereby prevents scratches on the nozzle surface 4.

摘要： PURPOSE:To make it possible to repair or to exchange nozzles for spraying wiping gas quickly, by mounting hollow supporting cylinders, attached to the nozzles and headers for spraying wiping gas on the surface to be plated of a hoop, on the supporting frame of a plating bath tank. CONSTITUTION:One end of a hollow supporting cylinder 3 is connected to the header 2 of a nozzle 1 for spraying wiping gas on the surface to be plated of a hoop which is taken out of a plating bath tank 7. The other end of the hollow supporting cylinder 3 is connected removably through a quick joint 29 to a gas pipe. The hollow supporting pipe 3 is supported above and outside the plating bath tank 7 by the frame through a rotatable joint 25 rotatably and removably. This mechanism makes possible rapid and easy loading and unloading of the nozzle 1 portion alone in repairment or exchange of the nozzle 1.

摘要： PURPOSE:To enable rotation of a ribbon coil with a short transfer distance and without damaging the wound-up shape of the coil by providing a mechanism sending laterally the coil loaded on the horizontal arm of an up-ender to a vertical arm. CONSTITUTION:A coil 18 carried from a coiler not shown in the figure to a fixed position E-E by a coil car 17 is transferred from the coil car 17 on to a coil transfer rack 23 on a horizontal arm 22. Next, the transfer rack 23 is sent laterally along the horizontal arm 22 by the operation of a cylinder 24 in accordance with the dimension of the coil 18 in the direction of width up to the point where the end face F of the coil 18 in the direction of the wind thickness comes into touch with the coil-receiving face G of a vertical arm 21. When this transfer is completed, the coil 18 is placed in the condition that the end face thereof in the direction of the wind thickness is received by the vertical arm 21, while the lateral face in the direction of width -- by the horizontal arm 22 and the transfer rack 23, and, being rotated at 90 degrees by the operation of another cylinder 25, is transferred directly on to a conveyor 27. Thus, a ribbon coil can be rotated on to a carrying device in the next step, with a short transfer distance and without damaging the wound-up shape thereof.

摘要： PURPOSE:To automate changing of upper taking up and lower taking up of titled device and to enable continuous taking up by providing a swing fulcrum shaft on an extension line connecting center lines of a revolution shaft, taking- up shaft of a carousel reel and other taking-up shaft. CONSTITUTION:When a band steel 6 is taken up on a taking-up shaft 3 an the coil 7 becomes a state of completely taken up, a rotary frame 17 and an endless belt 8 set to the frame 17 are rotated around a switch fulcurm shaft 4 by a lifting cylinder 16. Then, the belt 8 is wound on taking-up shaft 2, and the band steel 6 becomes a state of starting of taken up on the shaft 2. When taking up of the coil 7 is completed, the band steel 6 is divided by a shear provided on the inlet side of a deflector roll 5, and the tip of the band steel 6 is led to the shaft 2, and taking-up is started. In this case, upper taking-up or lower taking-up is made on the shaft 2 depending on surface condition of the band steel 6.

摘要： PURPOSE:To reduce a leading time considerably with an expensive device by rotating and leading a coil by means of a freely upward and downward movable snubber roller and guides on a freely travelable carriage above a drum to be mounted with the coil. CONSTITUTION:When a coil 1 is carried by a coil car 2 into a prescribed position, a leading reel drum 34 is inserted into the coil, and the car 2 moves downward. The 1st frame 15 is moved downward, and a snubber roller 13 circumscribes the coil 1. On the other hand, the 2nd frame 21 is moved downward and a leading guide 30 and a delivery guide 32 descend. In succession, a guide 30 turns downward and a touch roller 29 and an opener 35 are pressed onto the outside circumference of the coil 1 in adequate positions. When the coil 1 is rotated counterclockwise, a leading end part 6 is led out by the cooperative operations of the three 13, 29, 35, and is led out by a required length onto the guide 30. Thereafter, a coil retainer 18 descends to hold down the end part 6, and the car 2 ascends. The drum 34 and a carriage 28 are run synchronously to carry the coil 1 into the drum of an uncoiler.
