AI Technical Summary
The unreasonable water channel design of the water-cooled bearing seat of the continuous casting machine leads to poor water flow in the water channel holes, generating steam, causing bulging and leakage of the bearing seat. The existing treatment method affects production and is labor-intensive.
A water-cooled bearing seat for a continuous casting machine is designed. A semicircular water-cooling channel is formed by a guide groove and a groove cover. The guide groove has a U-shaped cross-section, and the inlet and outlet channels are symmetrically arranged. A V-shaped structure is adopted at the transition to reduce dead zones in water flow and prevent the deposition of iron oxide scale and sediment.
It effectively prevents water channel blockage, ensures normal cooling of the bearing seat, and reduces production impact and labor intensity.

Abstract
Description
Technical Field
[0001] The utility model relates to a water-cooling bearing seat for a continuous casting machine, belonging to the technical field of continuous casting production equipment in the metallurgical industry. Background Art
[0002] The continuous casting machine is divided into several sectors. Each sector roller consists of six sets of free rollers with a segmented roller structure and one set of drive rollers with a mandrel-type segmented roller sleeve structure. The free rollers and mandrel are internally water-cooled. The bearing seats of the free rollers and drive rollers are also water-cooled to ensure the operation of the bearings. The sector bearing seats are often exposed to harsh working conditions such as high temperatures and mechanical shock. Due to improper design of the water channels on the bearing seats, the water channel holes often have poor water flow. At high temperatures, the cooling water in the water channels vaporizes and produces steam, causing bulging and leakage in the bearing seats. In addition, to handle such faults, the entire sector is replaced and hoisted out to an offline maintenance site to address the fault point. This method affects production, is cumbersome, time-consuming, and labor-intensive for workers. Utility Model Content
[0003] The purpose of the utility model is to provide a water-cooled bearing seat for a continuous casting machine, which can reduce the existence of dead zones in water flow, prevent the deposition of iron oxide scale and silt from clogging the waterway, ensure the normal cooling of the bearing seat, and solve the problems existing in the background technology.
[0004] The technical solution of the utility model is:
[0005] A water-cooled bearing seat for a continuous casting machine comprises a bearing seat body, a water inlet channel, a guide groove, a flow groove cover, a water outlet channel and a bearing mounting hole. The guide groove is arranged on the bearing seat body along the bearing mounting hole. The flow groove cover and the guide groove are combined to form a semicircular water-cooling channel that matches the bearing mounting hole. One end of the semicircular water-cooling channel is provided with a water inlet channel that penetrates downwardly into the bearing seat body, and the other end of the semicircular water-cooling channel is provided with a water outlet channel that penetrates downwardly into the bearing seat body.
[0006] The transitions between the semicircular water cooling channel and the water inlet channel and between the semicircular water cooling channel and the water outlet channel are both V-shaped structures.
[0007] The water inlet channel and the water outlet channel are symmetrically arranged along both sides of the bearing mounting hole.
[0008] The cross section of the guide groove is U-shaped.
[0009] The flow channel cover plate and the bearing seat body are welded into an integral structure.
[0010] The beneficial effects of the utility model are: it can reduce the existence of water flow dead zones, prevent the deposition of iron oxide scale and mud and sand from blocking the waterway, and ensure the normal cooling of the bearing seat. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present invention will be further described below with reference to the accompanying drawings and examples.
[0015] Refer to the attached Figure 1-2 A water-cooled bearing seat for a continuous casting machine comprises a bearing seat body 1, a water inlet channel 2, a guide groove 3, a flow groove cover plate 5, a water outlet channel 6 and a bearing mounting hole 7. The guide groove 3 is arranged on the bearing seat body 1 along the bearing mounting hole 7. The flow groove cover plate 5 and the guide groove 3 are combined to form a semicircular water-cooling channel 8 that matches the bearing mounting hole 7. One end of the semicircular water-cooling channel 8 is provided with a water inlet channel 2 that downwardly penetrates the bearing seat body 1, and the other end of the semicircular water-cooling channel 8 is provided with a water outlet channel 6 that downwardly penetrates the bearing seat body 1.
[0016] In this embodiment, refer to the attached Figure 1-2 The water-cooled bearing seat of the continuous casting machine includes a bearing seat body 1, a water inlet channel 2, a guide groove 3, a V-shaped structure 4, a flow groove cover 5, a water outlet channel 6, a bearing mounting hole 7 and a semicircular water cooling channel 8. A guide groove 3 is opened on the bearing seat body 1 along the bearing mounting hole 7. The cross-section of the guide groove 3 is U-shaped. The flow groove cover 5 is welded to the bearing seat body 1 above the guide groove 3 to form a semicircular water cooling channel 8. The diameter of the semicircular water cooling channel 8 is larger than the diameter of the bearing mounting hole 7. The water inlet channel 2 and the water outlet channel 6 are symmetrically arranged on both sides of the bearing mounting hole 7. The upper ends of the water inlet channel 2 and the water outlet channel 6 are respectively connected to the semicircular water cooling channel 8.
