The shooter is connected to a gun that conveys the gunning material to the lance. This shooter can handle a heavier lance than workers can, and it enables operators to work far away from the steelmaking furnace. The device also operates at a higher speed than manual shooters and provides a higher-quality application. Geneva reduces refractory costs Refractory casting and gunning are replacing traditional bricklaying at Geneva Steel. Also, our consumption of refractory material is down to about half of what it was.
Geneva uses laser scanning to reduce refractory costs.
Lasers scan vessel linings almost daily to develop an ongoing record of lining wear. The cumulative data give engineers information they need to design linings with more uniform wear. Laser scanning allows us to use lower-quality refractory in areas of low wear. Shotcreting Interest in shotcreting has surged, says Brian Kellogg, general manager of monolithics at Harbison-Walker Refractories Co. in Pittsburgh. You get a lining with the same properties as material cast in forms, but without the forms.
