Embodiment Construction

[0012] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0013] refer to figure 1 and figure 2 , an eighteen-high rolling mill structure, including a rolling line adjustment device 1, a roll assembly 2, a side push cylinder 3, a pressing oil cylinder 4, a frame assembly 5, side support rolls 6, side rolls 7, work rolls 8, and intermediate rolls 9. Backup roll 10, two work rolls 8, two intermediate rolls 9, two support rolls 10, eight side support rolls 6 and four side rolls 7 form an eighteen-roll type, and the work roll 8 passes through the intermediate roll 9 by Back-up roll 10 is supported, and back-up roll 10 is connected with pressing oil cylinder 4, and the side support device of work roll 8 is contained in the front and back of rolling mill frame assembly 5 respectively, and is arranged up and down.

[0014] The side support device includes a side roller 7, a side support roller 6, and a side support bearing seat...

Abstract

The invention provides an eighteen-roller rolling mill structure. Side supporting devices of working rollers are respectively arranged in the front and at the back of as well as on and below a rolling mill machine frame assembly; each side supporting device comprises a side supporting bearing pedestal, a side roller and a side supporting roller; the side supporting device comprises a side driving cylinder which is provided with a displacement sensor and a servo valve for controlling the advancing and retreating positions of the side supporting device; when in a rolling work, the side supporting positions are set according to various technical parameters, so that the side deformation caused by the working rollers in a rolling process is counteracted and the rigidities of the working rollers are improved; with the adoption of the small-diameter working rollers and a side driving roller system mode, the demand of roller rigidity in the rolling process is ensured, and meanwhile, the rolling demand of an ultra-thin belt material is satisfied; and the rolling mill structure has the following advantages of high rolling mill opening degree, favorable lubrication for the roller and belt material, high speed, convenience to maintain equipment and low manufacturing cost of the equipment.

Description

technical field [0001] The invention relates to a rolling mill, in particular to an eighteen-high rolling mill structure. Background technique [0002] In recent years, with the further increase in market demand for cold-rolled thin plates, as well as the increasing demand for stainless steel and silicon steel thin plates, multi-roll rolling mills are increasingly favored by users. [0003] The foreign Sendzimir type 18-high rolling mill has its advantages: the rolling mill has high rigidity, the working roll diameter is smaller, and thinner products can be rolled. But it also has its disadvantages: the opening of the rolling mill is small, the lubrication of the rollers and the strip is poor, and the speed is low; the equipment maintenance is inconvenient; the equipment cost is high. Contents of the invention [0004] In order to overcome the above-mentioned shortcomings of the prior art, the object of the present invention is to provide an eighteen-high rolling mill str...
