Abstract
The invention relates to a middle roller cone of a twenty high rolling mill. The cone is a cone of multi-stage conicity and a double-stage conicity or third-stage conicity. The cone part of one middle roller of a twenty high rolling mill is improved by the invention, namely, the originally universal single conicity is improved into the double-stage conicity or the third-stage conicity; as the situation that part of a roller system is stressed too much is improved, the situation of uneven deformation of the corresponding position of a foil is lightened; a double-rib wave detect is eliminated; and the quality of the plate shape is remarkably improved.
Description
Technical field
The invention belongs to the roller mill technical field, particularly relate 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.
Summary of the invention
Technical problem to be solved by this invention 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 solution adopted for the present invention to solve the technical problems is: a kind of mill one intermediate calender rolls cone is provided, it is characterized in that: described cone is multistage tapering cone.
Described cone is second order tapering (0.3 °+0.7 °) or three rank taperings (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 present invention 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.

The specific embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used to the present invention is described and be not used in and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
Embodiment 1
As shown in Figure 2, the conical section of mill one intermediate calender rolls is improved to the second order tapering by original general single tapering, its cone is second order tapering (0.3 °+0.7 °), and the step conical after the improvement as shown in Figure 3.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
As shown in Figure 2, the conical section of mill one intermediate calender rolls is improved to the second order tapering by original general single tapering, its cone is three rank taperings (0.2 °+0.4 °+0.8 °), and the step conical after the improvement as shown in Figure 3.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 (2)
