Zusammenfassung:The invention provides an adjustable slag line tundish lifting hydraulic control method. Different electromagnets of a first electromagnetic directional valve in a lifting loop are controlled by an electric control cabinet to be powered on, and under the mutual cooperation effect of a synchronous motor, an oil inlet throttling valve and a balance valve, the functions of stable and rapid ascending and descending of a tundish can be achieved, and the process requirement of rapid lifting of a tundish is met; a second electromagnetic directional valve in a slag adjusting line loop is controlled through the electric control cabinet, the lifting loop is automatically cut off in the slag adjusting line process under the mutual matching action of an oil inlet throttling valve, a one-way valve, a two-way logic cartridge valve of the lifting loop and a synchronous motor, and the technological requirement for slow lifting of the tundish slag adjusting line is met. When a compensation loop is in a tundish lifting working
