摘要： PURPOSE: To reduce the energy necessary for alloying at the time of producing a galvannealed steel sheet. CONSTITUTION: The total Al content in a hot dip galvanizing bath is regulated to 0.10-0.20wt.%, and the temp. of the galvanizing bath is held at 500-580 deg.C. A steel sheet is passed through the galvanizing bath and galvanized. Then, the resulting galvanized steel sheet is heated, within 5sec just after wiping, at 5-50 deg.C and recuperated to produce the galvannealed steel sheet. For this process, a recuperative furnace of 1-10m length is provided at the position adjacently to the wiping device disposed above the hot dip galvanizing bath.

摘要： PURPOSE: To efficiently perform defoaming through a simple structure by providing a degassing pipe in a spot lower than a horizontal section by the specified distance on the way of an overflow pipe. CONSTITUTION: The diameter of an OF pipe 3 is denoted by (d) in a horizontal section 4 in which the OF pipe 3 starts to descend. A gas-blowing nozzle 6 is provided, so that the tip 5 thereof is positioned in a range of height higher and lower than the horizontal section by 2d and (d) while keeping the horizontal section 4 as a center. When gas 14 is ejected from the gas-blowing nozzle 6, bubbles 1 formed in a cleaning liquid tank 2 by ejector effect are sucked and introduced into the OF pipe 3. Bubbles after absorption are passed through the lower end 7 of the OF pipe 3 and recovered in the cleaning liquid tank 2. The gas after defoaming is discharged through a degassing pipe 8 but bubbling is not caused because the gas is not allowed to collide against the liquid level 15 in the OF pipe. The upper end of the communication part of the OF pipe 3 and the degassing pipe 8 is necessarily positioned in a spot lower than the horizontal section 4 in which the OF pipe starts to descend by >=3d in order to efficiently obtain defoaming effect.

摘要： PURPOSE:To prevent the generation of the plating surface defect occurring in scum and more particularly the problem of surface appearance arising from an alloying reaction by suppressing the generation of Zn vapor generated from the plating bath surface in a snout by cooling a snout bath surface. CONSTITUTION:A cooling gas header 6 is disposed downward on the plating bath surface in the snout 2 where a steel sheet 1 is immersed into the plating bath 3 in the snout part for hot dip metal coating and gaseous nitrogen of ordinary temp. to 200 deg.C is blown thereto from the cooling gas header 6 to cool the bath surface down to 420 to 440 deg.C and to suppress the generation of the vapor of the Zn from the bath surface. As a result, the generation of the vapor of the Zn generated from the bath surface is suppressed. The hot dip galvannealed steel sheet having the extremely good surface appearance is obtd. particularly with the alloying treated steel sheet.

摘要： PURPOSE:To simply separate a bottom dross from a hot dipping zinc bath at a low cost by arranging a settling box for separating the bottom dross in a hot dip galvanizing vessel, sucking the bottom dross in the galvanizing vessel bottom part and settling. CONSTITUTION:At the time of continuously applying the hot dip galvanizing to a long steel sheet 4 in the galvanizing vessel 1 containing the hot dipping zinc bath 13, the bottom dross 2 is deposited at the bottom part of the galvanizing vessel 1. This deposited bottom dross 2 is sucked from a sucking hole 5 in a guide tube 6 provided with a pump 6A and guided into the settling box 7 arranged in the galvanizing vessel 1 to settle the bottom dross 2 at the bottom part. Supernatant in the hot dipping zinc bath settling and separating the bottom dross 2 is returned back into the galvanizing vessel 1 from an opening 8 arranged at the upper part of the settling box 7 and again used as the hot dipping zinc bath 13. The bottom dross is separated from the hot dipping zinc bath in the simple device without high expense and the device is prevented from deterioration of the quality in the galvanized layer by sticking a part of the bottom dross 2 to the galvanized steel sheet 4.

摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method for a plating steel strip capable of being coated with a coating film in a plating line without a problem and finishing drying in the plating line without providing a new drying device when a plating surface is coated with a clear coating film in order to improve a peeling off-resistance property of the plating of a plating steel plate having a glare-proofing property.
SOLUTION: In the manufacturing method for the plating steel strip, a plating layer is formed on a surface of a steel strip and a roughness of a surface of the plating layer is made to 0.8 μm or more at Ra. The coating with coating film is performed before rolling up the steel strip after formation of the plating layer and is formed by coating the steel strip moved with a film of a coating liquid delivered from a slit. The coating liquid is a water-base coating. The temperature of the steel strip when the coating with the coating film is performed is made to 50-95°C. Since a roll is not used at coating, the coating film can be formed without any problem. A drying device after coating is not required and coating with a clear coating film can be performed on a plating line existing from conventional.

摘要： PROBLEM TO BE SOLVED: To provide a multi-layer film coating method for a metal plate capable of simultaneously coating a surface treatment film and a coating film without generating foaming by using a multi-layer simultaneous coating apparatus when a surface of the metal plate is coated with a multi-layer film containing a metal surface treating agent coating film and a solvent based coating film.
SOLUTION: In the multi-layer film coating method for the metal plate, when a film of the coating liquid is delivered from a plurality of slits and the moved metal plate is coated with these films to form the multi-layer film, the coating liquid coated at a side close to the metal plate of the multi-layer film is a water base metal surface treating agent and one or more of the coating liquid coated at a side far from the metal plate is a solvent based coating. The solvent of the solvent based coating is a water-soluble solvent. Since the water-soluble solvent is used, a moisture content in the water base surface treatment film is possibly dissolved in the coating and it can be permeated through the coating and escape into an atmosphere. As a result, the foaming is not generated.
