Abstract
A symmetrical belt-steering and tensioning system and apparatus for twin-belt continuous metal casting machines are disclosed. A rigid squaring shaft passes through a hollow tension and steering roll and is rigidly secured to torque arms at opposite ends of the roll assuring that this roll remains parallel with the driving roll at the other end of the carriage throughout the range of tensioning travel, these arms each being associated with tension thrust means and steering means. The geometrical relationships assure that tension in the casting belts remains essentially directly proportional to the fluid pressure in the thrust cylinders, while a pre-loading arrangement removes back lash from the pivots to improve steering precision and also provides mechanical advantage. A symmetrical synchronized steering action is applied to both ends of the tension-steering roll, and axial thrust control means operate to force the roll skewing movement to center at a predetermined point. Independent adjustment of the displacement of each end of the tension-steering roll from the pass line is provided by sleeves associated with the squaring shaft and bearings in the interior of the hollow roll. A high belt tension force can be applied because there are two main large diameter rolls at opposite ends of each carriage defining the belt path as a symmetrical oval shape. Wide casting belts of 116 inches in width or more are precisely steered and tensioned for continuously casting slabs 100 inches or more in width.
