Embodiment Construction
[0021] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.
[0022] Such as Figure 1 to Figure 6 As shown, the continuous casting roll includes a first segmented roll 1, a second segmented roll 2 and a mandrel 3, the mandrel 3 runs through the first segmented roll 1 and the second segmented roll 2, and at both ends of the mandrel 3 A rotary joint 6 and a transmission coupling 7 are respectively installed, wherein the transmission coupling 7 is connected to the mandrel 3 through a spline, and the first segmented roller 1 and the second segmented roller 2 are assembled on the mandrel 3 through a key. At the same time, when the external power is connected with the transmission coupling 7, the continuous casting rolls will run.
[0023] The rotary joint 6 is fixedly connected with the...

The invention provides a continuous casting roller, which belongs to the technical field of machinery. The invention solves the problem that the roller sections in the conventional continuous casting roller cannot be conveniently mounted and are unstable. The continuous casting roller comprises a first roller section, a second roller section and a spindle, rotating joints and drive couplings are mounted on both ends of the spindle, a middle bearing pedestal is arranged between the first roller section and the second roller section, and is mounted on the spindle through a bearing, a left supporting bearing pedestal and a right supporting bearing pedestal are arranged on both ends of the spindle through bearings, second end covers are mounted on the outer sides of the left supporting bearing pedestal and the right supporting bearing pedestal, second distance rings are respectively mounted on both sides of the left supporting bearing pedestal and the right supporting bearing pedestal, one end of each second distance ring, which is located on the inner side, abuts against the bearing, the other end of each second distance ring abuts against the corresponding roller section, a third distance ring is mounted between the second end cover mounted on the right supporting bearing pedestal and the bearing, and a size gap is arranged between the second end cover mounted on the left supporting bearing pedestal and the bearing. The continuous casting roller is convenient to mount, can be accurately positioned, and is highly stable.
Description
technical field [0001] The invention belongs to the technical field of machinery, and in particular relates to a continuous casting roll on a sector section of a continuous casting machine. Background technique [0002] In order to improve the internal quality of continuous casting slabs, small roll dense arrangement and light reduction technology have been widely used in the design of modern casting machines. With the extensive application of small roll dense arrangement technology in continuous casting equipment, in order to improve the small diameter roll Generally, the rigidity is in the form of segmented rolls. According to the selected roll diameter and the width of the casting machine, two-segmented, three-segmented and four-segmented rolls are generally used. One or two bearings for support. Most of the segmented roller structure of the continuous casting machine put into production at present is a structure in which a plurality of bearings are connected in series t...
