Description

Continuous mills are known for rolling strip with bending around rolls with a strip, containing a bed, at least three adjustable work rolls located in one plane, drive rolls, winding, unwinding devices and push mechanisms.

The proposed mill differs from the known ones in that any two adjacent pairs of work rolls containing a common adjustable roll are installed with a mutually perpendicular arrangement of planes passing through the axis of the rolls of each pair.

This embodiment allows you to independently change the radial solution of each pair of work rolls.

In FIG. 1 shows the proposed mill, General view; in FIG. 2 and 3 diagrams of options for placing work rolls with the number of rolls more than five (arrows indicate the action of the pressure devices).

The mill contains a bed 1, work rolls 2-6, pressure devices 7 10 (roll drive, unwinder and reel are not shown in the figure).

The placement of the work rolls has the following features. One of the rolls (roll 4) is fixed motionless (unregulated). Rollers 2,3,5 and 6 have individual pressure devices 369764 7 and can move independently of each other. Thus, it is possible to control compression in any pair of rolls

2-3, 3-4, 4-5 and 5-6. This is achieved due to the fact that the rolls located to the left and right of the roll 4 are arranged so that the plane passing through the centers of each previous pair of rolls is perpendicular to the plane passing through the centers of each subsequent pair of rolls adjacent to the previous one. In the general case, all rolls can have individual pressure devices and move independently of each other. In this case, the condition of mutual perpendicularity of the planes of the axes of adjacent pairs extends to all rolls. The number of pairs of rolls in the proposed mill can be any necessary.

The proposed continuous mill has the following advantages:

1. The possibility of independent regulation of compression in any pair of rolls; 2. The decrease in the number of pressure devices to η— 1, where And is the number

3θ · rolls; 3. Reducing the dimensions of the stand in length; 4. The increase in the arc of coverage of part of the rolls without additional devices.
