Water cooling roller

Abstract

The invention relates to a water cooling roller. The water cooling roller comprises an operating side shaft, a transmission side shaft and a roller, wherein inner plates, outer end plates and inner end plates are arranged on the operating side shaft and the transmission side shaft; a cylinder is arranged between the inner end plate and the outer end plate; a cover plate is arranged between the inner plate and the roller; the inner end plate, the outer end plate and the cylinder form an inner cavity; the inner plate, the cover plate, the outer end plate and the roller form an outer cavity; holes communicated with the inner cavity and the outer cavity are uniformly formed in the outer end plate; a first water channel is formed inside the operating side shaft; a plurality of second water channels penetrating through in the axial direction are uniformly formed in the wall thickness periphery direction of the roller; a third water channel is formed inside a driven side shaft; the first water channel is communicated with the inner cavity on an operating side; the second water channels are communicated with the inner cavity on a transmission side; the third water channel is communicated with the outer cavity on the operating side and the outer cavity on the transmission side. The water cooling roller has the advantages that by performing optimization design on the structure of the water cooling roller, the application of large-section forge pieces is reduced, the equipment manufacture cost is reduced, the water cooling roller is high in cooling speed and uniform in cooling, and the strip steel shape is good.

Description

technical field [0001] The invention relates to equipment of a cold rolling continuous annealing unit, and more specifically relates to a water-cooled roll. Background technique [0002] In the cold-rolled strip steel annealing unit, the roll cooling technology is to make the strip steel contact with the furnace roll with cooling water inside, and realize the cooling of the strip steel through heat conduction. This technology has low production cost and can realize rapid cooling. It is suitable for the production of cold-rolled strips and be widely used. However, the shaft head of the water-cooled roller is integrally forged, and the cross-sectional dimensions of the forgings are quite different. The weight of the water-cooled roller is too large, which also increases the power selection of the motor, which virtually increases the production and operation costs of the enterprise.

Problems solved by technology

However, the shaft head of the water-cooled roller is forged in one piece, the cross-sectional size of the forgings varies greatly, and the whole equipment is also heavy. Whether it is rough forging, machining, or assembly, there are certain difficulties, which leads to high production costs of the water-cooled roller.
