Description

Technical Field

[0001] The utility model relates to the technical field of continuous casting machines, in particular to an eccentric wheel cooling system of a continuous casting machine crystallizer vibration mechanism. Background Art

[0002] The production process of continuously casting high-temperature molten steel into ingots with certain cross-sectional shapes and certain dimensions is called continuous steel casting. The equipment required to complete this process is called a continuous casting equipment set. The electromechanical and hydraulic integration of steel casting equipment, continuous casting machine main equipment, cutting area equipment, dummy rod collection and conveying equipment constitutes the core equipment of continuous steel casting, which is usually called a continuous casting machine.

[0003] The main function of the crystallizer vibration mechanism is to make the crystallizer vibrate up and down. To be precise, it makes the crystallizer move along the radius of the continuous casting machine according to the given amplitude, frequency and waveform deflection characteristics to simulate the arc motion, making demoulding easier. In daily production, due to the high ambient temperature, the eccentric wheel of the crystallizer vibration mechanism is prone to temperature rise, which can easily cause the eccentric wheel bearing to lock at high temperature, affecting production efficiency. In current production, cooling water is used to cool the three bearings of the eccentric wheel separately. As long as the production is carried out, the water is poured without precise control, resulting in a waste of cooling water. In addition, in the high-speed production of the continuous casting machine under the high temperature environment in summer, the cooling effect of this method is not ideal. Utility Model Content
