摘要： PURPOSE:To reduce the generation of a camber by constituting a post-stage stand containing a final stand so that one of the upper and the lower work rolls or one of the upper and lower backup rolls can be driven to rotate. CONSTITUTION:In a cold rolling mill of an original plate for a surface treatment steel sheet having at least two stands, a pre-stage stand containing at least a first stand is constituted so that both the upper and the lower work rolls 3 or both the upper and the lower backup rolls 2 can be driven to rotate. Also, a post-stage stand containing at least a final stand is constituted so that one of the upper and the lower work rolls 5 or one of the upper and the lower backup rolls 4 can be driven to rotate. Accordingly, by bringing the post-stage stand containing the final stand to single drive, a camber caused by a peripheral speed difference of the work rolls can be reduced greatly. Also, since the operation rate is also improved, the productivity can be improved.

摘要： PURPOSE:To simplify the control of oil coating by experimenting the relation between the rotating speed of a pickup roll and the oil coated amt. per unit time and unit width selecting a regression equation and setting the relation between a line speed and pickup roll. CONSTITUTION:The line speed V of an object 4 to be coated with oil is detected by a line speed detector 6 and the signal thereof is supplied to an oil coated amt. control device 7 of an oil coating device for atomizing the oil such as rust perventive oil. The rotating speed (n) of the pickup roll relative to the line speed V is calculated in accordance with the inclinations Rc and Bc and the line speed V when said inclinations are set in setters 8a, 8b. The calculated value is determined as a target value. The target value and the rotating speed of a motor 9 to drive the pickup roll are compared and a control signal cs is outputted to a circuit 11 which in turn makes servocontrol of the motor 9, thereby controlling the rotating speed of the pickup roll 1. The uniform oil coated amt. is thus maintained.

摘要： PURPOSE:To maintains a gloss of a work roll surface of steel plate by electrodepositing Si matter of sodium silicate after electrolyting and washing of the steel plate surface. CONSTITUTION:In a washing process of a manufacture of cold rolled steel plate, an electrolytic cleaning of the steel plate in an electrolyte containing sodium silicate and caustic soda is carried out, the Si matter of sodium silicate is electrodeposited by 2-5mg/m on the surface of the steel plate. By this method, silica(SiO2) on the surface covers a concentrated material (Mn, Si, Al) deposited from the steel which has a function of shaving off attached material on the surface of a work roll when tempering and rolling are carried out, and a function directly not brought into contact with the concentrated material on the surface of the steel plate to the work roll directly, and so the concentrated material causing clowding does not stick and deposit on the work roll.

摘要： PURPOSE:To quantitatively decide a complicated operation conditions by varying each intermesh amount of plural roll sets and a plate stock tension, calculating the camber amounts in the width and length directions by a simulation and forming the combination that the estimation function thereof becomes smaller in order. CONSTITUTION:The strip 4 to which a tension is given by the inlet side bridle device 2 and outlet side bridle device 3 is straightened with its bending by the roll units U1-U5 that the work roll 5 diameter of a levelling mill 1 become larger in order. The combination of the intermesh amount M of the unit U1 and the tension is varied from the unit U1, the width direction camber amount Cs and length direction camber amount Ls of after straightening are calculated by the simulation and the estimation function phi calculated with an equation is made smaller. The integrated estimation function phi is made smaller in order by adding the units U2, U3 in order. With this technique, a complicated operation conditions are quantitatively decided by eliminating the contradiction that the width direction camber is converted into the length direction camber and the straightening can be bettered.

摘要： PURPOSE:To surely prevent jumping and to obtain a steel sheet having good sheet thickness accuracy with high efficiency by executing dry temper rolling in one stand on the front stage side of a temper rolling mill and executing wet temper rolling in the subsequent stands in succession thereto. CONSTITUTION:An annealed coil 8 is paid off from a pay off reel 7 and is subjected to surface rolling down in a dry state in the No.1 stand. A temper rolling liquid is spray-coated onto the strip 9 from a temper rolling liquid spray header 6 between the No.1 stand and No.2 stand. The strip is subjected to temper rolling in a wet state in the the No.2 and subsequent stands and is adjusted to the surface roughness meeting applications in the No.3 stand. The elongation at the yield point of the material is thus eliminated by the effect of the dry temper rolling in the front stage stands and the wet temper rolling without generating jumping is made possible in the rear stage stands.
