A die (for a continuous casting installation) that includes a movably mounted frame having a first subframe and a second subframe; a first broad-side insert which is positioned on the first subframe; and a second broad-side insert which is positioned on the second subframe. Narrow sides each having a narrow-side copper plate and abuting the two broad-side inserts are positioned between the two broad-side inserts. The die also has: a clamping device which is designed to exert, on the subframes, a clamping force that acts between the subframes; and an oscillation drive which is designed to make the frame oscillate in and counter to a horizontal width direction (H) relative to the narrow sides. A spring band assembly which guides the subframes is positioned on each subframe on sides which are opposite one another in the width direction (H).

A control device (1) for an oscillating table (6), comprising:a closed and pressurized hydraulic circuit (20),a hydraulic actuator (21) connected to said hydraulic circuit (20) and adapted to be connected to the mobile part of the oscillating table (6) to adjust the position thereof, in which said hydraulic actuator (21) is a double-acting cylinder having a first chamber (21a) and a second chamber (21b) delimited from each other by a sliding piston (22) rigidly connected to a first rod (31a) which is rigidly restrainable to said mobile part, in which said hydraulic circuit (20) comprises at least one reversible hydraulic pump (9) directly connected to at least one of said first chamber (21a) and second chamber (21b).

The present disclosure provides a high-vanadium high-speed steel and preparation method therefor, and use thereof, which relate to the technical field of high-vanadium high-speed steel. The preparation method includes: smelting raw materials to form a melt; impacting the melt to a cooling platform to form a high-vanadium high-speed steel casting billet; and performing a spheroidizing annealing treatment and a quenching and tempering treatment, so as to obtain a resultant. The spheroidizing annealing treatment includes: heating the high-vanadium high-speed steel casting billet to 820-910 C.; holding for 2-4 h; then cooling down to 450-550 C. at a cooling rate larger than 40 C./h; and then air cooling to a room temperature.
