Steel section rolling mill

A cooling box for a cooling arrangement configured to be mounted to a stand frame of an edger mill stand or a universal mill stand of a section mill for rolling steel sections, the edger mill stand being configured for rolling a workpiece in a plurality of back-and-forth passes into a steel section having a web and one or more flanges, wherein the cooling arrangement is mounted to the stand frame of the edger mill stand or the universal mill stand for cooling the workpiece while the workpiece undergoes rolling during one or more of the passes, the cooling box comprising:

• a spray head with spray openings for spraying jets of pressurized cooling liquid against the workpiece;
• at least one coupler for releasable locking engagement with an actuator of the cooling arrangement configured to move the cooling box relative to the stand frame of the universal mill stand or of the edger mill stand for adjusting a distance between the spray openings and the workpiece;
• and
• a fitting for connecting the cooling box to a cooling liquid supply.

A method of retrofitting a section mill with a cooling arrangement, wherein the section mill is configured for the rolling of steel sections and comprises a universal mill stand and an edger mill stand for rolling a workpiece in a plurality of back-and-forth passes into a steel section having a web and one or more flanges, each of the universal mill stand and the edger mill stand having a stand frame, the method comprising:

• providing a cooling box comprising a spray head with spray openings for spraying jets of pressurized cooling liquid against the workpiece;
• mounting the cooling box to the universal mill stand or the edger mill stand in lieu of a flange roll and fitting the cooling box to a pusher arranged on the stand frame;
• connecting the cooling box to a cooling liquid supply;
• and
• using the pusher as an actuator for moving the cooling box relative to the stand frame of the universal mill stand or of the edger mill stand for adjusting a distance between the spray openings and the workpiece.
