AI Technical Summary

Technical Problem

The crystallizer of the large section, large thickness single-flow straight arc-shaped wide-thick slab continuous casting machine has insufficient clamping force and is unbalanced, resulting in the crystallizer running cone and vibration being out of synchronization, resulting in the angle cracks and longitudinal cracks of the casting billet, affecting the quality of the billet.

Method used

A double-acting clamping cylinder of slab continuous casting machine crystallizer is designed to achieve clamping and loosening functions through the movement of the piston rod, and combine the disc spring and hydraulic system to ensure balance and stability of the clamping force.

Benefits of technology

The stable clamping of the crystallizer is achieved, avoiding the problem of running cone and vibration out of synchronization, and improving the quality of the casting billet and the stability of production.

Abstract

The utility model relates to a double-acting clamping cylinder of a slab continuous casting machine crystallizer, and belongs to the technical field of slab continuous casting machines in the metallurgical industry. According to the technical scheme, the oil filling device comprises a flange (1), a piston rod (2), a cylinder body (3), a disc spring (4), adjusting gaskets (5), a piston (6), piston rod sleeve seals (7), a flange bolt (10), a rod cavity oil filling port (11) and a rodless cavity oil filling port (12), the flange (1) is fixed to the cylinder body (3), the disc spring (4) is arranged in a rod cavity of the cylinder body (3), the adjusting gaskets (5) are arranged at the two ends of the disc spring (4) respectively, the piston rod sleeve seals (7) are arranged at the two ends of the piston rod (2) respectively, and the piston rod sleeve seals (7) are arranged at the two ends of the piston rod (2) respectively. And the flange (1) is provided with a rod cavity oil filling port (11) and a rodless cavity oil filling port (12). The crystallizer clamping device has the advantages that the crystallizer clamping and loosening functions are achieved through movement of the piston rod, the clamping effect is good, and the situation that due to unbalanced clamping force, a crystallizer deviates, vibrates asynchronously and the like can be avoided.
