Abstract
The utility model relates to an intermediate roll cone of a twenty-high roll mill. The intermediate roll cone consists of a cone (1), a first-order taper (2) and a second-order taper (3), wherein thefirst-order taper (2) is at one end of the cone and the second-order taper (3) is at the front end of the first-order taper (2); and the cone can also be provided with a third-order taper (4) at the front end of the second-order taper (3). By improving the cone part of the intermediate roll of the twenty-high roll mill, namely improving an original general single taper into two orders of taper orthree orders of taper, the intermediate roll cone overcomes the situation that a roll is locally applied with overlarge force, consequently reduces the situation that a corresponding position of foilmaterial deforms unevenly, eliminates the defect of double-rib wave and obviously improves the quality of plate shape.
Description
Technical field
The utility model belongs to the roller mill technical field, particularly relates to a kind of cone of mill one intermediate calender rolls.
Background technology
Rolled strip is thin more, and the sensitiveness of its inhomogeneous deformation is remarkable more, so the also difficult more control of plate shape.For mill, the flatness defect that occurs is limit wave and two rib waves easily, and this is the most common defective in nearly all mill plate shape control aspect.U.S.'s Sendzimir 20 roller reversable cold-rolling machines, the hydraulic pressure adjustment of backing roll roll shape is being arranged aspect the control of plate shape and having the adjustment means that an intermediate calender rolls of tapering is axially twitched, wave and limit wave have positive effect to these two kinds of adjustment means in the band to improving, but to two rib waves to improve effect not remarkable.Mill lacks effective means always aspect the control of two rib waves, thickness of strip is thin more, and two ribs wave defective is obvious more, as shown in Figure 1.
The utility model content
Technical problem to be solved in the utility model provides a kind of improved mill one intermediate calender rolls cone, to eliminate the two ribs wave defective that occurs easily in the operation of rolling, improves milled sheet shape.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of mill one intermediate calender rolls cone is provided, form by cone, the first rank tapering and the second rank tapering, the described first rank tapering is positioned at an end of cone, and the described second rank tapering is positioned at the front end of the first rank tapering.
When described cone was the second order tapering, the first rank tapering and the second rank tapering were respectively (0.3 °+0.7 °).
Described cone also is provided with the 3rd rank tapering that is positioned at the second rank tapering front end.
When described cone was three rank taperings, the first rank tapering, the second rank tapering and the 3rd rank tapering were respectively (0.2 °+0.4 °+0.8 °).
The generation of two rib waves is main relevant with an intermediate calender rolls roll shape of mill.Because mill adopts an intermediate calender rolls that has single tapering axially to twitch and adjusts plate shape, in tapering and position, plain-barreled roll boundary, because the sudden change of roll shape tapering, making roller is that local pressure is bigger, cause the inhomogeneous extensional of relevant position band, this is the main cause that causes two rib waves.
Beneficial effect
The utility model passes through the improvement to the conical section of mill one intermediate calender rolls, promptly be improved to second order tapering or three rank taperings by original general single tapering, because roller is that the excessive situation of local pressure is improved, the inhomogeneous deformation situation of foil relevant position alleviates, two ribs wave defective is eliminated, and strip shape quality obviously improves.

Fig. 2 is an intermediate calender rolls local pressure figure.
Fig. 3 is single tapering schematic diagram.
Fig. 4 is the utility model step conical schematic diagram.
Be labeled as among Fig. 4: cone 1; The first rank tapering 2; The second rank tapering 3; The 3rd rank tapering 4.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment 1
The conical section of mill one intermediate calender rolls is improved to the second order tapering by original general single tapering, and wherein the first rank tapering 2 and the second rank tapering 3 are respectively (0.3 °+0.7 °), and the step conical after the improvement as shown in Figure 4.After having adopted an intermediate calender rolls that has step conical, because roller is that the excessive situation of local pressure is improved, the inhomogeneous deformation situation of foil relevant position alleviates, and two ribs wave defective is eliminated, and strip shape quality obviously improves.
Embodiment 2
The conical section of mill one intermediate calender rolls is improved to three rank taperings by original general single tapering, and wherein the first rank tapering 2, the second rank tapering 3 and the 3rd rank tapering 4 are respectively (0.2 °+0.4 °+0.8 °), and the step conical after the improvement as shown in Figure 4.After having adopted an intermediate calender rolls that has step conical, because roller is that the excessive situation of local pressure is improved, the inhomogeneous deformation situation of foil relevant position alleviates, and two ribs wave defective is eliminated, and strip shape quality obviously improves.
Claims (4)
1. mill one an intermediate calender rolls cone is made up of cone, the first rank tapering and the second rank tapering, and it is characterized in that: the described first rank tapering is positioned at an end of cone, and the described second rank tapering is positioned at the front end of the first rank tapering.
2. a kind of mill one intermediate calender rolls cone according to claim 1 is characterized in that: the first rank tapering and the second rank tapering are respectively (0.3 °+0.7 °).
