摘要： PROBLEM TO BE SOLVED: To correctly enable aligning even when there is a disorder on the outer peripheral shape of the coil by measuring the weight and the width of the strip metal coil, operating the outside diameter of the coil by using measured values, giving an alignment distance to a coil lifter by using an operated result, and controlling elevating and lowering. SOLUTION: The coil 1 is placed on a weighting part 4 and coil weight W is measured. Next, the coil 1 is placed on a coil transfer means 6, and when it passes through a width measuring part 5, after a coil width B is measured, it is placed on a coil lifter 9. The measured coil weight W and coil width B are sent to an arithmetic and control part 7, and an alignment distance X is found by the arithmetic and control part 7. The alignment distance X is given to an actuator 12, and control to the coil lifter 9 is started. Simultaneously with the control start, the pisition of a hydraulic cylinder 11 is elevated and lowered by the alignment distance X and is stopped. Consequently, the coil lifter 9 is elevated and lowered by the alignment distance X and alignment is completed.

摘要： PROBLEM TO BE SOLVED: To remove foreign matters in a short time by jetting roll detergent to the contact part between a work roll and a back-up roll from the downstream side of the work roll, forming liquid pools and removing the foreign matters by dissolving the foreign matters on the roll surfaces. SOLUTION: The surface of a sheet is inspected on the outlet side of a strip 10 to which temper rolling is applied and the dirt on the roll is detected. Jetting nozzles 5 are provided on the back sides of the contact parts 13 between the work rolls 11 and the back-up rolls 12 of stands 1, 2 and the detergent is fed from a roll-detergent tank 7 with a pump 6. When the information of the dirt of the roll is outputted, automatic valves 4 are opened and the roll detergent is jetted from the nozzles 5 to the rolls, the liquid pools 9 are formed in the contact parts 13 between the work rolls 11 and the back-up rolls 12 and the dirt on the rolls are dissolved and removed. Like this, the foreign matters removing action is begun immediately after confirming the sticking of the foreign matters, so defects are minimized and dangerous manual works in a rolling mill are eliminated.

摘要： PURPOSE:To prevent a rolling oil injecting nozzle from being clogged and to increase a rolling time due to reduction of repairing by supplying hot water to the inner part of the injecting nozzle just before the injection of the rolling oil starts or just after the injection stops. CONSTITUTION:Rolling oil and warm water are set respectively by an oil tank 1, a warm water tank 2 to prescribed concentration and temperature, fed forcibly by an oil pump 3 and a warm water pump 4, mixed compulsorily by a mixer 7 into a temporary emulsion state and injected from the injecting nozzle 9 to a prescribed part through a header 8. The rolling oil, the warm water are fed and stopped by an oil selector 5, a warm water selector 6. When the rolling oil begins injection, the warm water selector 6 is opened and the oil selector 5 is opened and transferred to emulsion as the warm water is injected. When the injection of the rolling oil is stopped, the oil selector 5 is closed and after injection of the warm water only is held continuously for a prescribed time, then, the warm water selector 6 is closed to stop the supply of the warm water.

摘要： PURPOSE:To stably obtain good quality level sheets and to improve the productivity by forming a layer of Cr or Cr3C2 on bright rolls in a 2nd stand for skin-pass rolling by a two-stand rolling mill. CONSTITUTION:It is necessary to prevent generation of wear particles caused by rolling a steel sheet S in a 1st roll stand 1 and deposition of wear particles on the surface of bright rolls 2' to prevent degradation of surface roughness of the bright rolls 2' of a 2nd stand 2 and to stably obtain a black plate having a uniform surface roughness for plating in skin-pass rolling. Then, a layer of Cr or Cr3C2 having good tight adhesion to the rolls 2', wear resistance and high brightness is formed on the surface of the rolls 2'. Therefore, good quality black plates having a very little degradation tendency for tin plating are continuously obtained.

摘要： PURPOSE:To straighten cambers of a hard rolled steel sheet and to reduce the cost by spraying water or warm water onto the top or bottom surface of a cold rolled steel sheet in the inlet side of the final stand and changing a friction coefficient at the bitting part of a work roll by adjusting the spraying amount. CONSTITUTION:A cold rolled steel sheet 1 after annealing is rolled by a high draft of 10-50% by a double reduce rolling mill to manufacture the hard cold rolled steel sheet 1. In the case of generating cambers in that rolling, a friction coefficient at the sheet biting part between work rolls 12A, 12B is changed by spraying water or warm water onto the top or bottom surface of the sheet 1 in the inlet side of the final stand S of a mill and then cambering tendencies of the sheet 1 are changed. Further, the sheet 1 prevented from cambering is obtained by adjusting the spraying amount of water or warm water.

摘要： PROBLEM TO BE SOLVED: To prevent metallic swelling and breaking and to obtain a smooth steel strip by rolling a crushing and reducing roller back and forth in plural number of times on a weld joint formed by electric resistance welding and also varying the rolling down force for each rolling. SOLUTION: A lap joint part is formed by superposing in a welding equipment the rear end of a steel sheet of a preceding coil and the front end of a succeeding coil, and then electric resistance welding is performed. Then, a succeeding crushing and reducing roll 9 is passed on the welded zone with a reduction set about 10-20kg/cm . Successively, the roll is passed in the second reciprocating rolling with a reduction set about 35kg/cm . As a result, no metallic swelling or breaking is generated around the weld zone, enabling smooth skinpass rolling to be performed. In this method, it is desirable to successively increase the rolling-down force each time.
