Description

Technical Field

[0001] This utility model relates to the field of bearing housing sealing, and in particular to a bearing housing for a slab continuous casting machine fan-shaped section continuous casting roll. Background Technology

[0002] The sector section of the continuous casting machine is a core component. Located after the crystallizer, its main function is to support, guide, and cool the billet with a liquid core emerging from the crystallizer. Its structure includes multiple casting rolls arranged in an arc shape to match the solidification shrinkage shape of the billet, effectively preventing deformation of the billet due to its own weight and the internal static pressure of the molten steel.

[0003] In practical use, the continuous casting roll bearing housing in the existing technology is prone to vibration because the continuous casting roll needs to bear a large load during operation and the continuous casting roll itself is relatively heavy. This vibration affects the stability and working performance of the continuous casting roll. Utility Model Content

Detailed Implementation

[0016] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.

[0017] Combined with appendix Figure 1-3 As shown, a slab continuous casting machine sector section continuous casting roll bearing housing includes a bearing housing body and an auxiliary clamping mechanism for assisting in clamping the bearing housing body. The bearing housing body includes a base 1 and a top cover 2 mounted on the base 1. Each end of the base 1 is provided with a first mounting foot 1a. The auxiliary clamping mechanism includes a fixing frame 3, which includes two uprights 3b and a horizontal frame 3a disposed on the upper end of the two uprights 3b. The outer end of the uprights 3b is provided with a second mounting foot 3c. There are four clamping units, which are symmetrically arranged on the horizontal frame 3a for clamping the top cover 2.

[0018] The aforementioned clamping unit includes a clamping screw 4 that is threaded into the crossbar 3a, and a clamping plate 5 disposed at the lower end of the clamping screw 4. This design is simple in structure, convenient in operation, and provides reliable clamping.

[0019] The lower end face of the aforementioned clamping plate 5 is provided with a positioning protrusion 5a, and the aforementioned top cover 2 is provided with a positioning groove 5b corresponding to the positioning protrusion 5a.
