Embodiment 1

[0049] After the transformation, the structure of the roller body is as follows: figure 1 As shown, one end of the first water inlet pipe 3 is connected to the left roller end 2 through the first fixed sleeve 9, and the other end is connected to the right roller end 4 through the second fixed sleeve 8; one end of the second water inlet pipe 7 is connected to the other end through the second fixed sleeve 8 It is connected with the right roller end 4, and the other end is closely connected with the rotary joint 6. Such as image 3 As shown, the size of the first water inlet pipe 3 is Ф34×4×2400mm, the size of the second water inlet pipe 7 is Ф33×4×450mm, and the size of the first fixed sleeve 9 and the second fixed sleeve 8 is Ф50×7.5×70mm. The four original materials are all low carbon steel Q345-A, which has good weldability.

[0050] The appropriate gap between the second water inlet pipe 7 and the second fixed sleeve 8 is very important. If the gap is too large, the water...

[0055] After the transformation, the roller structure is as follows: figure 1 As shown, one end of the first water inlet pipe 3 is connected to the left roller end 2 through the first fixed sleeve 9, and the other end is connected to the right roller end 4 through the second fixed sleeve 8; one end of the second water inlet pipe 7 is connected to the other end through the second fixed sleeve 8 It is connected with the right roller end 4, and the other end is closely connected with the rotary joint 6. Such as image 3 As shown, the size of the first water inlet pipe 3 is Ф34×4×2400mm, the size of the second water inlet pipe 7 is Ф32×4×450mm, and the size of the first fixing sleeve 9 and the second fixing sleeve 8 is Ф50×7.5×70mm.

Embodiment 3

[0057] The metallurgical hot-rolled slab water-cooled roll includes the above-mentioned roller table and roller shafts connected at both ends of the roller table. The roller shaft is inserted into the end of the roller table to form a fit and fixed connection. A water inlet and a water outlet connected with the axial through hole in the roller table are provided.

Abstract

The invention discloses a metallurgical hot rolled plate blank water-cooling roller way, a water-cooling roller and a mounting method of the metallurgical hot rolled plate blank water-cooling roller way, and belongs to the technical field of steel rolling mechanical equipment. The metallurgical hot rolled plate blank water-cooling roller way comprises a roller body, a left roller end, a right roller end, a bearing block, a rotary connector, a water inlet cavity and a water return cavity, and further comprises a first water inlet pipe and a second water inlet pipe, wherein the two ends of the first water inlet pipe are connected with a first fixing sleeve and a second fixing sleeve correspondingly, one end of the second water inlet pipe is connected with the right roller end through the second fixing sleeve, the other end of the second water inlet pipe is tightly connected with the rotary connector, and the radial interval between the second fixing sleeve and the second water inlet pipe is 0.5-1 mm. During installation, the two ends of the first water inlet pipe are connected with the first fixing sleeve and the second fixing sleeve; by carrying out static balance testing on the roller body, the smoothness is adjusted in advance at the earlier stage; and the effect that the interval is reserved between the second water inlet pipe and the second fixing sleeve in the radial direction is ensured. According to the metallurgical hot rolled plate blank water-cooling roller way, the service life of the roller way can be prolonged, the overhaul and maintenance time is shortened, and cost is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of steel rolling machinery and equipment, and more specifically relates to a water-cooled roller table for metallurgical hot-rolled slabs, a water-cooled roller and an installation method thereof. Background technique [0002] The roller body of the metallurgical hot-rolled slab conveying roller table, because the surface of the roller body is in direct contact with the hot slab, the roller body not only requires high-speed rotation but also bears the weight of the slab at a high temperature above 1000°C, so the roller body must be made in a water-cooled structure . The existing waterway in the inner cavity of the roller is separated into and out of cold and hot water through a rotary joint. The specific structure is as figure 2 Shown: roller body 1, left roller end 2, water inlet pipe, right roller end 4, bearing seat 5, swivel joint 6, water inlet chamber 10, return water chamber 11. [0003] The workin...
