Abstract

PURPOSE:To control a roll crown, by a method wherein a heat-transmitting medium is supplied into a plurality of zones divided in the expanding direction of a roll, the temperature of each of the zones is regulated from the inside of the roll, and the amount of thermal expansion of the roll in the diametral direction is changed. CONSTITUTION:A plurality of sets of annular chambers 15a, 15b, 15c... connected to each other in the circumferential direction are provided in a main body 2 of the roll in the direction of the axis of the main body 2, and drilled holes 16a, 16b, 16c... for supplying the heat-transmitting medium and drilled holes 16a', 16b', 16c'... for returning the medium which holes are provided in a shaft 1 are connected to the chambers 15a, 15b, 15c... respectively. The zones A, B, C... for individually regulating the temperature of each of the chambers 15a, 15b, 15c... are provided. In controlling the temperature, the heat-transmitting medium is individually passed through each of the chambers 15a, 15b, 15c..., whereby the shape of the roll is controlled. Accordingly, the outside diametral shape of the roll can be easily set to be a predetermined shape.

DETAILED DESCRIPTION OF THE INVENTION The present invention controls the temperature distribution in the roll axis direction to a desired state, thereby varying the amount of thermal expansion at any position in the roll axis direction, thereby changing the roll outer diameter shape. The present invention relates to a method and apparatus for controlling the shape of a roll.

For example, in the case of rolling rolls, a roll bending device is installed in the roll chock, the rolls are slightly crossed, or six rolls are used to make the roll gap in the roll axis direction uniform and However, these methods limit the pattern of irregularities in the width direction of the sheet thickness that can be corrected. That is, the distribution of the roll gap given in the width direction of the plate has at most one extreme value, and if the thickness of the plate before rolling has two or more extreme values, it cannot be corrected. However, the original plate thickness often cannot be corrected in this way. Furthermore, if the roll is longer than the width of the sheet, the rolling load may deform the roll and cause the edge of the sheet to become thinner (edge drop).

On the other hand, in the case of rolls for rubber plastics, in addition to the need to control the roll gap distribution, it is also necessary to maintain a uniform roll temperature. To maintain uniformity, it is necessary to flow a large amount of heat medium, which goes against the demand for energy conservation and makes it difficult to further improve the temperature uniformity in the roll axis direction.

Temperature control is also performed in other zones B, etc. in the same manner as in zone A. The temperature of each zone A, B, etc. takes into account the coefficient of thermal expansion of the roll body (2) and the roll outer layer (3). The entire roll is determined to have a predetermined shape. That is, by controlling the temperature within a certain adjustable range, the roll can have a desired outer diameter at any position in the fine direction. For example, 1
In the case of a steel roll of 000φ, the outer diameter increases by 0.1 m with a temperature increase of 10°C.

In this method, the temperature is controlled by passing a heat medium through multiple sets of radial holes and axial grooves in the roll body (2), so the amount of cooling water injected onto the roll surface can be varied in the axial direction. Compared to the conventional method of adjusting the temperature of the roll, it is possible to change the temperature inside the roll in a shorter time, and it is also possible to obtain a large temperature difference in the axial direction.

In addition, in the first embodiment of the present invention, the case where the shaft and the pull body are separate is described, but it is also possible to implement it as an integral structure, and the hole provided in the shaft and the roll The spoke-shaped holes provided in the main body may not communicate through the grooves provided on the outer periphery of the shaft, but may be made to communicate directly without the grooves, and the holes provided in the shaft for heat medium return may be communicated directly. It is possible to have a small number of holes common to multiple zones, or holes common to all zones, instead of providing them for each zone.
An electric heater is provided in the middle of each zone, and the spoke-shaped holes can be used exclusively for cooling.Although the installation of thermocouples is not explained in the second and third embodiments,
As in the case of the first embodiment, it is possible to detect the temperature in each zone, the temperature detection sensor is not limited to a thermocouple, but various types can be adopted, and the heating medium supply means is as follows: In addition to what was explained in the first embodiment, for example, it is also possible to maintain the heat medium in the tank at a constant temperature using a heater or the like and supply it to the rolls by a pump, and to expand the rolls. High-temperature steam may be sent as a heat medium to the part to be contracted, water may be sent as a heat medium to the part to be contracted, and various other changes may be made without departing from the gist of the present invention. Of course.

According to the roll shape control method and device of the present invention, (1) The temperature of the entire inside of the roll can be changed in a short time by passing a heat medium through spoke-shaped holes and grooves provided at various parts in the axial direction of the roll. At the same time, the temperature distribution in the roll axis direction can be changed to a desired state. Therefore, the outer diameter of the roll can be set to a desired dimension in the axial direction of the roll, and the outer diameter of the roll can be set to a predetermined shape.

(il) Since the outer diameter shape of the rolls can be changed in various ways, when used for rolling, it is possible to reduce the gap between complex rolls, which could not be achieved with conventionally used roll bending, roll cross, six-tier rolls, etc. The shape can be controlled, and even complex round and shape control becomes possible.

Tsukuda) By changing the gap distribution between the rolls in advance and additionally performing quick-response mechanical control such as roll bending and roll crossing, it is possible to correct large irregularities and complex irregularities on the board that cannot be corrected by these methods alone. It can be quickly corrected and edged quadruples can be eliminated.

4v) In conventional calenders used for rubber and plastics, the entire roll was made into one temperature control zone by holes passing in the axial direction as a drill trawl. Since two sets of temperature control zones are provided, it is possible to further reduce temperature non-uniformity in the fine direction, and at the same time, the flow rate of the heat medium can be reduced as the length of the flow path flowing in the roll axis direction is shortened. This can contribute to energy conservation.

等積々の優れた効果を奏し得る。It can produce excellent effects.
