Abstract
Description
TECHNICAL FIELD
[0001] The utility model belongs to hot rolling roller technical field, concretely relates to a device that improves the cooling effect of hot rolling lower roller. BACKGROUND
[0002] The conventional hot rolling roller cooling is through the nozzle and sprays the emulsion on the roller surface, and the spraying of the upper roller is from top to bottom, and the emulsion will flow along the roller to the whole roller surface, so that the whole roller surface is uniformly cooled, while the spraying of the lower roller is from bottom to top, and most of the emulsion directly splashes after being sprayed on a certain point on the roller surface, so that the lower roller surface is not uniformly cooled, which leads to a large temperature rise of the lower roller during rolling, and the lower roller is prone to cracking, thereby greatly shortening the service life of the roller. SUMMARY
[0003] The utility model discloses a device that improves the cooling effect of hot rolling lower roller to solve the problems in the above background.
[0004] To achieve the above object, the utility model provides the following technical scheme: a device that improves the cooling effect of hot rolling lower roller, including collecting groove, the collecting groove is arc-shaped arrangement, the collecting groove left and right sides each is equipped with a connecting piece, the connecting piece is equipped with a plurality of connecting bolts, the collecting groove is equipped with two limit plates between two connecting pieces, and the connecting piece is fixed in the roller bearing seat inner side by bolt.
[0005] Preferably, a circular small hole is arranged at the center of the collecting groove, and a movable plug is detachably installed on the circular small hole.
[0006] Preferably, the collecting groove, the connecting piece and the limit plate are made of 316 high-temperature-resistant stainless steel.
[0007] The utility model discloses a technical effect and advantage:
[0008] 1. The device can collect the emulsion used for cooling in the arc-shaped collecting groove, so that the roller is immersed in the emulsion, and the roller is uniformly and sufficiently cooled by rotating the roller, thereby reducing the risk of cracking of the roller due to local high temperature.
[0009] 2. Meanwhile, the collecting groove bottom is perforated, the movable plug is installed, the movable plug is opened after production to empty the accumulated emulsion, and the collecting groove is cleaned. DRAWINGS
[0010] Figure 1 The utility model discloses a schematic diagram.
[0011] In the drawing: 1 collecting groove, 2 bolt, 3 connecting piece, 4 movable plug. DETAILED DESCRIPTION
[0012] The technical solutions in the embodiments of the present application will be clearly and completely described with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application and are not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the protection scope of the present application.
[0013] The utility model provides a kind of device for improving the cooling effect of hot rolling lower roller as Figure 1 As shown in a kind of device for improving the cooling effect of hot rolling lower roller, including collection groove 1, collection groove 1 is arranged in arc, and each of the left and right sides of collection groove 1 is provided with a connecting piece 3, the connecting piece 3 is provided with a plurality of connecting bolts 2, and the collection groove 1 is further provided with two limit plates between the two connecting pieces 3, and the connecting piece 3 is fixed to the inner side of the roller bearing seat by the bolt 2.
[0014] Specifically, a small circular hole is provided in the center of the collection groove 1, and a movable plug 4 is detachably installed on the small circular hole.
[0015] Specifically, the collection groove 1, the connecting piece 3 and the limit plate are all made of 316 high-temperature-resistant stainless steel.
[0016] Working principle:
[0017] During the production and rolling process of the hot rolling mill, when the sprayed emulsion cools the lower roller, the device can collect the emulsion used for cooling in the arc-shaped collection groove 1, so that the roller is immersed in the emulsion, and the roller is uniformly and fully cooled by rotating the roller, thereby reducing the risk of cracking of the roller due to local high temperature. At the same time, the bottom of the collection groove is opened, and the movable plug 4 is installed, the movable plug 4 is opened after production to empty the accumulated emulsion, and the collection groove is cleaned.
[0018] Finally, it should be noted that: the above only describes preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some technical features, as long as they are within the spirit and principles of the present application.
