摘要： PURPOSE:To enhance the reliability of the device by providing mechanical stopper means for prohibiting the contact of spindle supporting members and a roll-driving spindle at the time of rolling. CONSTITUTION:The spindle supporting members 10 are placed in the non- operation positions parted from the roll-driving spindle 4 at the time of rolling and are moved to the operation positions where the members come into contact with the roll-driving spindle 4 and the spindle 14 is supported by these members 10 at the time of changing the roll 2. The spindle supporting members 10 are driven between the non-operating positions and the operating positions by actuators 12. The contact of the spindle supporting members 10 and the roll- driving spindle 4 at the time of rolling is, thereupon, prohibited by the mechanical stopper means 13. The generation of heat by the contact of the spindle supporting members and the spindle during high-speed rotation is surely prevented.

摘要： PURPOSE:To enable various rearranging patterns by providing respectively rails to be exclusively used to work rolls and intermediate rolls to assure space and providing a moving machanism to be commonly used. CONSTITUTION:Rolls 6, 7 are removed by a push puller 13 in the case of rearranging upper and lower work rolls 6, 7. The position of a side shifting table is then side-shifted. The engagement between the push puller 13 and upper and lower intermediate rolls 5, 8 is released, and the puller 13 is inserted into a rolling mill 1 by means of cylinders 14, 15. The puller 13 can force the fresh upper and lower work rolls 6, 7 into the mill 1 without contact with the rolls 5, 8. An oil pressure is finally applied on the hook cylinder to remove an upper work roll hook 16 and a lower work roll hook 17 from the roll 6 and the roll 7 respectively and the cylinders 14, 15 are contracted to return the puller 13 to the home position. The roll rearrangement is thus completed.

摘要： PURPOSE:To reduce a rolling interruption time for even a small rolling unit and to improve the productivity by proceeding rolling at the roll stand one less than the final stand at the time of opening and changing the final stand rolls at a changing point of a strip surface quality in tandem cold rolling. CONSTITUTION:In the case of continuously rolling a strip 1 by a tandem cold mill and changing the surface quality from bright to rough, as an example, final stand work rolls 3 are opened and changed from a bright roll to a rough surface roll and the rolling proceeds by bright rolls of a stand 10 being one less than the final stand. It is also performable that a rough surface is rolled by drafting the final stand roll and a bright surface is rolled by the roll one less than the final roll with the final stand roll being opened. A rolling interruption time caused by roll changing is remarkably reduced and the productivity of rolling for even a small rolling unit is improved.

摘要： PURPOSE:To enable quick actuation of title device and to prevent the generation of slide between a coil and a coil car by friction with a mandrel at the time of moving the metal coil by moving the mandrel without moving the weighty metal coil. CONSTITUTION:A torque generated by an electric motor 16 is transmitted through a spindle 17 and gears 18 to a coupling 19. The mandrel 15 supported by the coupling 19 and a supporting mechanism 12 receives a power from the coupling 19 to wind the coil 2. The coil car 14 supports the coil 2 in the peripheral direction and prevents loading the weight on the mandrel 15. Then, the diameter of the mandrel 15 is reduced to make a clearance between the inner diameter of the coil and the mandrel 15. The mandrel supporting mechanism 12 is moved by a cylinder 11 to pull out the mandrel 15 from the coil 2. Then, it is loaded by the coil car 14 on a coil conveyer to carry out.

摘要： PURPOSE:To prevent production of the product, and to miniaturize the equipment by interposing the conductive fluid between the energizing roll and the metallic strip to supply the current to the metallic strip, and heating the metallic strip by the Joule's heat. CONSTITUTION:A low temperature side energizing roll 4 and a high temperature side energizing roll 5 made of the conductive material are connected to each other, and a metallic strip 1 is traveled between the rolls. The current is generated by passing this metallic strip 1 through an annular transformer 6, and the metallic strip 1 is heated by the Joule heat to execute the continuous heat treatment. In this energizing and heating method, the high temperature side energizing roll 5 is arranged at the position to be dipped in the conductive liquid 3 stored in a tank 2, and the conductive liquid 3 is interposed between the energizing roll 5 and the metallic strip 1. This constitution connects the energizing roll 5 to the metallic strip 1 in an electrically sufficient and uniform manner, and prevents generation of the spark and thermal crown.

摘要： PURPOSE:To improve the precision for remaining length calculation for coil tail end automatic deceleration at process line inlet side. CONSTITUTION:As the device measures a number of coiling of remaining coil to precisely grasp remaining length of a coil 1, a number of coiling is measured by the television camera, which has the resolution enough to identify sheet thickness and picks up coil side face, and by processing a picture 8. Further, a remaining coil length is calculated from a coil inside diameter, outside diameter and remaining number of coiling, deceleration timing is determined in comparison with the deceleration start remaining length calculated from the present passing speed and deceleration rate. By improving deceleration timing precision, there is no need to start deceleration in early time, the productivity of coil processing is improved. Also it is made possible to set lessened loop quantity, and make the coil processing equipment compact.

摘要： PURPOSE:To obtain products without surface flaw and having uniform roughness by providing electric discharge machines in a metal plate mill and using a roll coolant as a working fluid. CONSTITUTION:A strip 9 is rolled with the metal plate mill having upper and lower work rolls 1, 2 and back-up rolls 3, 4. In that metal plate mill, the electric discharge machines 5, 6 with which the surface working of the upper and lower work rolls 1, 2 is executed are provided. The roll coolant is used as the working fluid by using rolling fluid spray headers 7, 8. A ferromagnetic body is used as a consumable electrode for electric discharging machining. The electrode is oscillated in the axial direction of the work roll and electric discharge machining conditions are controlled in accordance with the rotational speed of the work roll. In this way, a cold rolled steel sheet and surface treated steel sheet excellent in image clarity after coating are obtained.
