Abstract
The utility model provides a roll profile of a working roll for controlling a strip steel section shape. The roll body of the working roll is composed of a middle curve section and symmetrical side curve sections on the two sides, a sine or cosine function curve is adopted as the middle curve section, and the length of the middle curve section is 85%-94% of the width of rolled strip steel. Biquadrate or fifth-power or sixth-power curves are adopted as the side curve sections, and the total length of the side curve sections is 85%-94% of the difference which is the length of the roll body of the working roll minus the width of the strip steel. A three-section curve mode is adopted in the roll body, the control requirements for the convexity of the strip steel can be met, the thickness reduction of the sides of the strip steel is facilitated, and therefore the strip steel section shape control capacity is improved, and the aim of comprehensively controlling the strip steel section shape and strip shape is achieved.
Description
Technical field
The utility model belongs to the mechanical equipment of steel rolling field, particularly a kind of continuous hot-rolling mill shape of working roll that can effectively control crown of strip.
Background technology
Along with the development of scientific and technological level and being growing more intense of steel market competition, control to belt steel product requires also more and more higher, it no longer is confined to the index aspects such as traditional thickness, width, for meeting technological requirement and improving the product lumber recovery, convexity and the edge thinning of strip section had to clear and definite requirement.The essence that crown of strip is controlled is exactly the control to milling train carrying roll gap, and the Aperture precision that only need to control the roll gap midpoint with THICKNESS CONTROL is different, and section configuration is controlled and must be controlled the full roll gap shape in rolled piece width span.In the situation that mill type is definite, roll forming becomes that crown of strip is controlled the most directly, the most effective means, many crown of strips and flatness Control Technology are mostly carried out around the roll forming that changes roll, as the plate shape control technology essence such as CPC and UPC all are the innovation of roll forming.
Summary of the invention
The utility model provides a kind of shape of working roll that can control crown of strip, reasonable combination by roll shape curve, when meeting the strip profile requirement, realization is with the edge thinning of steel, thereby improve the crown of strip control ability, reach the purpose of crown of strip and plate shape Comprehensive Control.
For this reason, the solution that the utility model is taked is:
A kind of shape of working roll of controlling crown of strip, is characterized in that, the described working roll body of roll is comprised of middle part curved section and monosymmetric limit section curved section; The middle part curved section adopts function curve, and limit section curved section adopts repeatedly square curve.
Described function curve is sine curve or cosine curve.
Described repeatedly square curve is biquadratic curve, five power curves or six power curves.
The 85-94% that described middle part curved section length is the rolled band steel width, two limit section curved section total lengths are the 85-94% that the working roll barrel length deducts strip width.
The beneficial effects of the utility model are:
Because the working roll body of roll has adopted the syllogic curve form, not only can meet strip profile and control requirement, and can contribute to control the attenuate of steel edge portion, thus improve the crown of strip control ability, reach the purpose of crown of strip and plate shape Comprehensive Control.
The accompanying drawing explanation
Fig. 1 is the shape of working roll schematic diagram of controlling crown of strip.
In figure: working roll 1, middle part curved section 2, limit section curved section 3.L
1for middle part curved section length, L
2for limit section curved section length.
The specific embodiment
As seen from Figure 1, the shape of working roll that the utility model is controlled crown of strip is that the body of roll of working roll 1 has been divided into to three sections, i.e. middle part curved section 2 and monosymmetric limit section curved section 3.Middle part curved section 2 adopts cosine curve, also can adopt as required sine curve.And limit section curved section 3 can adopt the biquadratic curve, also can adopt five power curves or six power curves, the concrete repeatedly square curve form adopted depends on the control needs of crown of strip.
Middle part curved section length L
1be generally 90% of rolled band steel width, and the total length of two limit section curved sections 3 is 2L
2for working roll 1 barrel length, deduct 90% of strip width.Figure 1 shows that middle part curved section 2 adopts cosine curve and limit section curved section 3 to adopt the working roll 1 roll forming figure of biquadratic curve.
Claims (4)
1. a shape of working roll of controlling crown of strip, is characterized in that, the described working roll body of roll is comprised of middle part curved section and monosymmetric limit section curved section; The middle part curved section adopts function curve, and limit section curved section adopts repeatedly square curve.
2. the shape of working roll of control crown of strip according to claim 1, is characterized in that, described function curve is sine curve or cosine curve.
