Continuous casting mold has oil pressure regulation cylinder with directional selection valves which are operated by any of various control apparatus

摘要

Side walls (2,3) formed by plate constitute a continuous casting mold which is adjusted with an oil hydraulic cylinder (7) for regulation in order to set predefined continuous casting cross-section shape. Directional selection valves (15,27A,27B,27C) for oil hydraulic cylinder, are operated by a three point control unit (31), a high degree control unit (23) or a control unit which has a wide pulse output.
