Abstract
The utility model relates to an intermediate roll, comprising a roll body (1). The utility model is characterized in that the one head of the intermediate roll is straight without conicity and the other head is provided with two sections or multi-sections of conicity (2). The conicity of the utility model is changed into the type of two sections or multi-sections of conicities, so that the service lives of a front door and a back door and an antithrust bearing are prolonged greatly, the material plate type with section is controlled better and the scratching rate between the material layers with section is greatly reduced, thus improving the quality of the product quality.
Description
Technical field
The utility model relates to ten four-high mills, is specifically related to the intermediate calender rolls used in a kind of ten four-high mills, belongs to cold-rolling stainless steel steel band field.
Background technology
Ten four-high mills are commonly used in the cold-rolling stainless steel steel band field, and ten four-high mill host machine part are made up of backing roll, back lining bearing, two intermediate calender rolls, an intermediate calender rolls and working roll.Cooperation between each parts is played crucial effects to the quality of product, and an intermediate calender rolls is again the most important thing, and during production, two one intermediate calender rolls are formed one group of use.
According to producing needs, an intermediate calender rolls needs the grinding tapering, is convenient to rolling.The past people adopt in the bipyramid one, as Fig. 1.Can reduce the destruction of axial force to thrust bearing in the bipyramid one, the position reaches requirement in one but can't regulate when thickness of strips and width change in rolling.If separately debugging go up or next in understood side wave and produced catcher mark, can only twitch simultaneously and allow steel band in next in the centre of an intermediate calender rolls, can only change in one when tapering is improper makes troubles to work.Someone improves the back and bores with single, and one section tapering as Fig. 2, in the operation of rolling, can be regulated tapering in by taking out roller arrangement.To go up an intermediate calender rolls as Fig. 2 and twitch, just equal to increase tapering to transmission side; To go up an intermediate calender rolls and twitch, just equal to reduce tapering to fore side.Thereby plate shape is controlled preferably and improved.But because the tapering gradient is bad in flat segments and the processing of tapered section position greatly, steel band is easy to generate 1/4 ripple to this tapering, the strip aberration in rolling; And front and back door and thrust bearing often damage, and are easy to generate the interlayer scratch, and template is relatively poor.
Summary of the invention
Technical problem to be solved in the utility model is: the intermediate calender rolls that at the problems referred to above, the life-span of designing a kind of front and back door and thrust bearing improves greatly, the band template is better controlled, the scratch rate significantly reduces between tape layer.
Technical solution of the present utility model: an a kind of intermediate calender rolls, comprise roll body, it is characterized in that, a straight zero draft of an intermediate calender rolls, there are two sections or multistage tapering in the other end.
During production, two one intermediate calender rolls are formed one group of use, and staggered putting is as Fig. 3.
The utility model tapering changes two sections or multistage form into, makes the lateral stressed maintenance of roll always in the operation of rolling, thereby has reduced the axial force of roll, and the life-span of front and back door and thrust bearing improves greatly, has reduced production cost.In addition, in the tapering original position one breeze way can be arranged when roll is contacted with an intermediate calender rolls, roll easily produces sharply distortion down, thereby the scratch phenomenon is controlled preferably between template and tape layer, the band template is better controlled, and the operation of subsequent handling is guaranteed; The scratch rate significantly reduces between tape layer, has improved product quality.
Description of drawings
Accompanying drawing 1 is one of a former intermediate calender rolls structural representation, and accompanying drawing 2 is two structural representations of a former intermediate calender rolls, and accompanying drawing 3 is the utility model structural representation.
The specific embodiment
A kind of embodiment of the present invention is described in conjunction with the accompanying drawings.
An a kind of intermediate calender rolls comprises roll body 1, it is characterized in that, and a straight zero draft of an intermediate calender rolls, there are two sections or multistage tapering 2 in the other end.
Claims (1)
1. an intermediate calender rolls comprises roll body (1), it is characterized in that, and a straight zero draft of an intermediate calender rolls, there are two sections or multistage tapering (2) in the other end.
