Embodiment Construction
[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0027] Such as figure 1 with figure 2 As shown, the adjustable cooling roll in this embodiment includes a cylindrical roller sleeve 1. The sleeve 1 is provided with a long hole 2 in the cylindrical wall structure between the two ends, and the long hole 2 is in the annular section of the roller sleeve 1. A plurality of equiangular intervals are arranged on the circumference of, and the two ends of the long hole 2 are closed ends. At the ...

The present invention provides an adjustable cooling roller. A roller sleeve is provided with long holes between two ends of the roller sleeve; cylinder ports of two sides of the roller sleeve are provided with through holes communicated with the long holes; a first shaft head and a second shaft head are respectively sealed and fixed at the two sides of the roller sleeve and enclose a sealed cavity body; the first shaft head is provided with a first axial hole, and a water return pipe is disposed in the first axial hole in a penetrating manner; the first axial hole and the water return pipe are sealed at one end of an inner side of the roller sleeve; a first radial hole communicated with the through holes is disposed in the first shaft head, and the first radial hole is communicated to the first axial hole; the second shaft head is provided with a second axial hole, one end of the second axial hole is communicated with the sealed cavity body, and the other end of the second axial hole is an enclosed end; and a second radial hole communicated with the through hole is formed in the second shaft head, and the second radial hole is communicated to the second axial hole. Temperature of the roller surface is adjusted by adjusting medium flow, different requirements are satisfied, and heat dissipation efficiency is largely increased.
Description
Technical field [0001] The invention relates to the technical field of rolls, in particular to an adjustable cooling roll. Background technique [0002] Rolls are important parts of rolling mills in rolling mills. They use the pressure generated by a pair or a set of rolls to roll steel. It mainly bears the effects of dynamic and static loads, wear and temperature changes during rolling. [0003] The rolls of the prior art are affected by external force extrusion and materials during work, and the temperature of the rolls rises rapidly. How to control the temperature of the rolls to be constant is a key issue. In the existing design of fluid cooling roll, the fluid flows in the inner cavity of the roll to achieve the purpose of cooling. The problem is that the fluid cannot fill the cavity during cooling, which causes the roll to be cold and hot. During the rotation, the roll is hot and cold. Alternate, the faster the speed, the higher the alternating frequency, the roll will appe...
