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 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 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 reduce the wear of the bearing, and to prevent the bearing from damage due to the meandering movement of the strip, by specifying the diameter of the journal of the sink roller for curling and conveying the strip to be plated, to be above 0.5 times of the outer diameter of the roller, at the molten zinc plating apparatus. CONSTITUTION:The sink roller 2 for curling and conveying the strip 1 to be plated is arranged within the molten zinc plating bath. The roller 2 is attached to the frame 4 through the bearing 3; the bearing 3 possesses the diameter larger than the outer diameter of the sink roller 2 and acts as the oil film bearing. Hereupon, the diameter of the bearing 3 fittable to the diameter of the journal of the sink roller 2 is specified to be at least 0.5 times of the outer diameter of the sink roller 2; thereby, the surface pressure of the oil film bearing is reduced, and the speed of outer surface is increased. Owing to this reduction of the surface pressure and the increase of the speed of outer surface, the wear of the bearing 3 can be reduced, so that the fall of operational efficiency and the increase of operational expenditure and the product cost, are prevented. Moreover, the meandering of the strip depending on the difference in the amount of wear of the bearing can be prevented.
