摘要： PURPOSE:To prevent the sticking of a steel strip to an electrode plate without practically deteriorating an effect in straightening the C warpage of the strip by setting a cushion nozzle at a specified position in the longitudinal direction of the electrode plate. CONSTITUTION:The cushion nozzle is set on the outlet side of the electrode plate in its longitudinal direction to prevent the sticking of a steel strip 5 to the electrode plate 2. Meanwhile, the nozzle is preferably set at the center of the electrode plate in its longitudinal direction to maximize an effect in straightening the warpage of the strip 5. The set position of the nozzle is experimentally specified to meet the requirements, and the ratio of the distance (m) between the electrode plate inlet and the nozzle to the distance (n) between the nozzle and the electrode plate outlet is controlled to (1:4) to (1:2).

摘要： PURPOSE:To improve the C warpage straightening effect, to decrease the distance between electrode plates and to reduce the power cost by specifying the position of a cushion nozzle. CONSTITUTION:One cushion nozzle on the convex surface side of a steel strip is set at the surface position of one electrode plate. The other cushion nozzle is set at a position projecting from the setting surface of the electrode plate toward the strip side. Consequently, a plating soln. injected toward the convex surface of the strip is supplied between the strip and electrode plate, the pressure of the plating soln. is increased in a space to the right of the strip, and the C warpage is straightened and reduced. The distance x2 between the electrode plate surface and the concave surface side of the strip and the distance x1 between electrode plate surface and the convex surface side of the strip are almost equalized, and the C warpage amt. x0 of the strip is reduced.

摘要： PURPOSE:To prevent the transverse oscillation of a steel strip in a titled device by installing an induction type linear motor on the upper stream side than a steering rolls in the cooling zone of a continuous heat treatment furnace and acting the thrust in the direction opposite from an advancing direction upon the steel strip. CONSTITUTION:A steel strip 1 passed through a continuous heat treatment furnace 2 is dipped in a plating bath 4, and is regulated of the coating weight of plating by gas wiping nozzles 6. The strip passes through a zero spangle device 7 and a galvanealing furnace 8 and is coiled. During this time, the strip is acted with tensile forces by bridle rolls 91, 92, but the tensile forces are weakened by the elongation generated in the steel strip by the effect of the heat of the furnace 2; therefore the strip is apt to oscillate transversely during the passage through the nozzles 6, the device 7 and the furnace 8. Therefore, electricity is conducted to a linear motor 10 to act the thrust in the direction opposite from the advancing direction of the strip 1 upon the strip 1 during operation. The tension on the strip 1 during the passage through the furnace 2 is weakened by said action and the tension on the strip 1 after the passage through the bath 4 is increased, whereby the transverse oscillation of the strip is prevented.

摘要： PURPOSE: To inhibit the generation of hydrogen chloride and to efficiently recover metallic zinc by adding an acidic salt to a metallic halide as a principal component, adding the resulting flux to top dross, and agitating them.
CONSTITUTION: Top dross 2 rising to the surface of a plating bath 1 is gathered and enclosed by a partition frame 3, or it is scooped up, put in a crucible 4, and melted by heating with a heater 5. An acidic salt such as NaHCO
3 is added to a metallic halide such as ZnCl
2 , and the resulting flux is charged into the top dross 2 and agitated. By this operation the acidic salt is converted into a basic substance by thermal decomposition, and the substance causes a neutralization reaction together with generated hydrogen chloride. By this reaction the generation of hydrogen chloride is inhibited. After the agitation zinc oxide in the dross is separated from metallic zinc and floats as ash, so by removing the ash, metallic zinc can be recovered.

摘要： PURPOSE:To effectively prevent the over-coating of both edges of a steel sheet by regulating the angle of jetting of gas from auxiliary nozzles so that jets of gas from the auxiliary nozzles and a jet of gas from a wiping nozzle reach the steel sheet at the same height. CONSTITUTION:A pair of auxiliary nozzles 14 are set on a wiping nozzle 12 placed opposite to a steel sheet 11 pulled up from a hot dipping bath 13 in the direction of an arrow so that the nozzles 14 confront both edges of the steel sheet 11. Each of the nozzles 14 has been fitted with an angle regulator 16. When the distance between the nozzle 12 and the steel sheet 11 shifts from a position A to a position B, the direction of jetting of gas from the nozzles 14 to the steel sheet 11 can be turned on the position of the intersection B1 of the direction of jetting of gas from the nozzle 12 and the shifted steel sheet 11 with the angle regulators 16. Jets of gas from the nozzles 12, 14 can be made to reach the steel sheet at the same height, so the over-coating of both edges of the steel sheet is effectively prevented and uniform sticking is attained in the lateral direction of the steel sheet.
