Patent ID: 8162033

Claim:
A method of supporting and guiding a cast strand after leaving a strand casting mold in a strand guide having a first roller bridge on one of two opposite wide sides of the cast strand and having four corners, a second roller bridge on the other wide side of the cast strand and having four corners, and respective first and second rows of rollers on each of the bridges engaging the respective wide sides of the strand, the method comprising the steps of: providing four respective first hydraulic positioners connecting the corners of the first roller bridge to a first fixed support and four respective second hydraulic positioners connecting the corners of the second roller bridge to a second fixed support, hydraulically positioning the first row of rollers by the first positioners at an acute angle to the neutral phase of the cast strand as the strand moves between the roller bridges, and hydraulically positioning the second row of rollers by the second positioners individually and independently of the positioning of the first set of rollers, asymmetrically to the first row of rollers relative to the neutral phase of the cast strand in the event of asymmetrical cooling and an asymmetrical neutral phase of the strand, and at an acute angle to the neutral phase of the cast strand as the strand moves between the roller bridges.
