Abstract: To reduce the cost of RH ladle lifting hydraulic system and improve the speed control function, taking the system pressure and the maximum speed as the target, the parameter optimization was discussed basing on the design datum and experiences of past typical projects. By studying the system designed by institutes at home and broad, the common ladle lifting hydraulic systems were analyzed and compared.

Key words: RH ladle lifting hydraulic system, hydraulic system parameters, hydraulic system scheme
