The shell is then separated from the crystallizer by vibrating the crystallizer. Therefore, the crystallizer plays a very important role in the continuous casting production process. The wide face of the crystallizer is clamped by four clamping cylinders. Once the oil leakage is serious, the crystallizer may be replaced unplanned. The quality of the replacement of the sealing ring of the clamping cylinder directly determines the service life of the clamping cylinder and the service life of the crystallizer online, so it is necessary to standardize and standardize the replacement of the sealing ring of the oil cylinder.

[0003] The existing sealing ring installation device does not have a piston anti-falling measure, so that when the sealing ring is installed, the sealing ring will pop off when it is separated from the cylinder and contacts the piston, resulting in unsuccessful installation. SUMMARY

[0004] The purpose of the application is to provide a sealing ring installation device for a piston of a clamping cylinder of a continuous casting machine crystallizer to solve the above problems.
