摘要： PURPOSE:To improve the material quality of a cold rolled steel strip and to prevent shape collapsion of a product in the stage of subjecting the steel strip to continuous annealing with a molten metal as a medium by setting the bath temp. of the molten metal at a specific temp. CONSTITUTION:The bath temp. of a molten metal is set within the target heating temp. of a cold rolled steel strip +100 deg.C in a continuous annealing stage in which the steel strip is subjected to an overaging treatment by heating, soaking and cooling with the molten metal as a medium. More specifically, said temp. is the range of the strip temp. of the case in which the molten metal is used for heating up to the soaking temp. and in the first half of the heating means up to about 400 deg.C strip temp. when the molten metal is used as a heating means. The bath temp. is set at the target value of the sheet temp. +100 deg.C. It is necessary to set the bath temp. of the molten metal within the target cooling temp. of the steel strip + or -100 deg.C range in the cooling stage as well. A molten salt may be used in place of the molten metal.

摘要： PURPOSE:To control an end point temp. at a high cooling rate with good accuracy and to reduce the cycle for annealing by immersing a steel strip prior to entrance to a heating zone and after slow cooling into a molten medium and maintaining the specified temp. of the steel strip. CONSTITUTION:A molten medium vessel 5 contg. molten Pb, etc. is provided in front of a heating zone 6 in continuous annealing and a cold-rolled steel sheet prior to entrance into a heating zone 6 is immersed in and passed through the medium by which the steel sheet is preheated. The steel sheet is then passed through the heating zone 6, a soaking zone 7 and a slow cooling zone 7a for primary cooling and is then immersed in and passed through a vessel 9 for the molten medium having the common compsn. as the compsn. of the molten medium used in the stage of preheating, by which the steel sheet is temporarily cooled down to the overaging temp. The steel sheet is then passed through an overaging zone 10 and a secondary cooling zone 11. The steel strip is maintained quickly at the bath temp. after the immersion by using such molten medium, by which the rate of heating and cooling is improved.

摘要： PURPOSE: To prevent the fluttering of a strip during passage by determining the speed of the material passing between press rolls from the circumferential speed of conveying rolls and the distance between the conveying rolls and the press rolls and controlling the circumferential speed of the press rolls.
CONSTITUTION: The number of revolution of the lower conveying roll 1-1 is detected with a detector 8-1 and the signal thereof is inputted to an arithmetic device 9-1 which outputs the circumferential speed value of the roll 1-1. The number of revolution of the upper conveying roll 1-2 is detected and is processed in the same manner as mentioned above. The arithmetic unit outputs the circumferential speed value of the roll 1-2. Both circumferential speed values are inputted to an arithmetic unit 7 for a speed reference. The speed of the strip at which the strip contacts with the press rolls 3-1, 3-2 is calculated from the input values thereof and the disposed distances between the rolls 3-1, 3-2 and the rolls 1-1, 1-2. The calculated value is outputted to a control device 6 for the press roll speed so that the rolls 3-1, 3-2 are rotated at the same circumferential speed as the speed in the stage of passing the strip.

摘要： PURPOSE: To uniformly cool a strip at a high speed by specifying the distance between the tip of an each cooling gas blowing nozzle and the strip and the projecting length of the nozzle and pressing the strip perpendicularly with press rolls which are so disposed as not to face each other.
CONSTITUTION: The strip S subjected to heating and soaking is introduced into a cooling zone where the cooling gas is blown from the nozzles 18 of gas injectors 15 disposed to face each other along a passing line of the strip S to cool the strip. The nozzles 18 are projection type round hole nozzles which are provided zigzag in a large number on the front face 17 of a cooling chamber 16. The distance Z between the strip S and the tips of the nozzles 18 is specified to ≤70mm and the projecting length (h) of the nozzles is specified to ≥(100-Z)mm. A pair of the press rolls 31 are disposed diagonally to the strip S to press the strip surface in the perpendicular direction by a driving device 33. The fluttering of the strip S is thereby thoroughly prevented and the uniform cooling of the strip in the transverse direction thereof is efficiently executed.

摘要： PURPOSE:To dissolve a substance to be dissolved remaining to a filter, in a method wherein a suspension having a hardly soluble substance to be dissolved suspended therein is supplied to a tank through the filter to use the solution of the tank, by recirculating a part of the solution to the filter. CONSTITUTION:A hardly soluble substance to be dissolved (e.g., NiCO3) is suspended in a mixing tank 10 and the resulting suspension is supplied to a tank 12 through a filter 11 while the filtered suspension stored in the tank 12 is sent to an electrolytic cell 13 by a pump 14 to perform plating. A part of said plating liquid is again supplied to the filter 11 by an arranged pipe 20 and the undissolved hardly soluble substance to be dissolved remaining to the filter 11 is dissolved to be introduced into the tank 12. That is, because the undissolved hardly soluble substance to be dissolved can be perfectly dissolved by supplying a part of the plating liquid to the filter from the tank while holding the plating liquid to a normal composition, this inventive industrial effect is large.
