Embodiment 1

[0021] Such as figure 1 and figure 2 As shown, an adhesive combined vertical roller includes a roller sleeve 1 and a shaft core 2, and the roller sleeve 1 and the shaft core 2 are bonded and fixed by a cylindrical part holding glue 4, and the cylindrical part holding glue 4 is methacrylic acid Ester retaining rubber is produced by Hubei Huitian Rubber Industry Co., Ltd. The working temperature of the cylindrical parts holding glue 4 is -55-150°C, the shear strength is 15-32MPa, the viscosity is 125-7500mPa·s, the filling gap is 0.05-0.1mm, the initial solidification time is 10min, and the performance is good , a wide range of applications; the surface roughness of the joint surface 3 of the roller sleeve 1 and the shaft core 2 is Ra0.8.

[0022] The method of use is as follows: Remove oil, dust, and rust from the surface of the joint surface 3 of the roller sleeve 1 and the shaft core 2, clean it with 755 surface treatment agent and dry it (755 surface treatment agent is a ...

Embodiment 2

[0025] The difference between this embodiment and embodiment 1 is that the cylindrical parts holding glue 4 with a filling gap of 0.25-0.3 mm is used, that is, the gap between the joint surface 3 of the roller sleeve 1 and the shaft core 2 is 0.25-0.3 mm.

Embodiment 3

[0027] The difference between this example and Example 1 is: the surface roughness of the joint surface 3 of the roller sleeve 1 and the shaft core 2 is Ra6.2, and the joint surface 3 with the middle roughness is selected to test the performance of the assembly after the holding is completed.

Abstract

The invention discloses an adhesive combined vertical roller, and particularly relates to a vertical roller used for hot rolled strip steel. The adhesive combined vertical roller comprises a roller sleeve and a shaft core which are glued and fixed through a cylindrical part fixation adhesive. A methacrylic ester fixation adhesive serves as the cylindrical part fixation adhesive. The working temperature of the cylindrical part fixation adhesive is -55 DEG C to 230 DEG C, the shear strength of the cylindrical part fixation adhesive is 15-32 MPa, the viscosity of the cylindrical part fixation adhesive is 125-7500 mPa s, the filling gap of the cylindrical part fixation adhesive is 0-0.5 mm, and the initial fixing time of the cylindrical part fixation adhesive is 10-60 min. The surface roughness of the combination face of the roller sleeve and the shaft core is Ra0.4 to Ra12.5. The adhesive combined vertical roller solves the problem that the vertical roller cracks due to unreliable factors of press fit force transmission of interference linkage, key linkage and the like and excessively-large assembly stress, and has the beneficial effects of being easy and convenient to assemble and stable in fixation force; and the machining accuracy can be reduced, the manufacturing cost can be reduced, the assembly process can be simplified, the production efficiency can be improved, and the energy consumption can be reduced.

Description

technical field [0001] The invention relates to an adhesive combined vertical roll, in particular to a vertical roll for hot-rolled strip steel, and belongs to the technical field of roll assembly. Background technique [0002] Due to the large diameter ratio of the roll body to the roll neck of the vertical roll used in the hot strip mill and the short roll neck at the lower end, a riser much thicker and longer than the lower end roll neck of the finished product needs to be used to meet the requirements of roll body compensation during integral casting. In order to ensure that the roll body and roll neck are free from casting defects such as porosity, porosity, and inclusions, the ratio of gross to net is particularly large, and the production cost of the blank is particularly high, while the production cost of the combined nesting method will be greatly reduced. [0003] The roller sleeve of the combined vertical roller is generally produced by the centrifugal casting met...
