Abstract
The utility model belongs to a production facility in metallurgical industry, and in particular relates to a middle roll of a twenty high rolling mill, which comprises a roll body, wherein one end of the roll body is a cone. The middle roll is characterized in that the cone has two-step taper of 0.3 degree + 0.7 degree. By utilizing the middle roll of a twenty high rolling mill to roll thin plates, the condition in which partial force of the roll system is excess is remarkably improved, uneven deformation of relevant positions of the thin plates is reduced, quarter buckle is eliminated, and quality of rolled thin plates is remarkably improved.
Description
Technical field:
The utility model belongs to the production facility of metallurgy industry, is specifically related to an a kind of intermediate calender rolls of mill.
Background technology:
The roller of mill is fastened down and is arranged symmetrically in the up-down rollers case, and working roll, intermediate calender rolls space are arranged very compact, adopt backing roll to carry out the glacing flatness adjustment at present, and purpose is to eliminate by the uneven problem of the local thickness of rolled piece.Along with the demand in market, thin type sheet material demand is more, when rolling thin type sheet material, because roller is that local pressure is excessive, causes the thin type sheet deformation, produces two ribs wave phenomenon, and band steel board thickness is thin more, and two ribs wave phenomenon is serious more.Because backing roll can not be eliminated two ribs wave phenomenon, thus more effective measures must be adopted, to eliminate two ribs wave phenomenon.
Summary of the invention:
The utility model aims to provide a kind of intermediate calender rolls that can eliminate a kind of mill of two ribs wave phenomenon.
The technical solution of the utility model is: comprise roll body, an end of roll body is a cone, it is characterized in that cone is the second order tapering, is 0.3 degree+0.7 degree.
Adopt the rolling thin type sheet material of the utility model, obviously having improved roller is the excessive situation of local pressure, and inhomogeneous deformation situation in light sheet relevant position alleviates, and has eliminated two ribs wave phenomenon, and rolling light sheet quality obviously improves.
Description of drawings:
Fig. 1 is the structure chart of the utility model embodiment.
Among the figure: 1. roll body 2. cones
The specific embodiment:
Embodiment: shown in Figure 1, present embodiment comprises roll body 1, and an end of roll body 1 is a cone 2, it is characterized in that cone 2 is the second order tapering, is 0.3 degree+0.7 degree.
Claims (1)
1, an a kind of intermediate calender rolls of mill, it comprises roll body, an end of roll body is a cone, it is characterized in that cone is the second order tapering, is 0.3 degree+0.7 degree.
