ABSTRACT:
A frictionless strip support for supporting a metallic strip conveyed along a feed path in a treatment process. The support including at least one hydrostatic chute including a plurality of confined hydrostatic chambers having apertures therein for a supply of a pressurized treatment liquid such as molten metal, and at least one pair of hydrostatic guides positioned downstream of the hydrostatic chute. Each hydrostatic guide has a confined hydrostatic chamber with apertures therein for supply of a pressurized treatment liquid such as liquid metal. The frictionless support also includes a pump for supplying the pressurized treatment liquid through the apertures and to the confined chambers such that the treatment fluid maintains the strip spaced from the hydrostatic chute and the hydrostatic guides by hydrostatic force of the pressurized liquid normal to the strip surface as the strip is conveyed across the hydrostatic chute and the hydrostatic guides. In metal coating processes, such as zinc coating, the hydrostatic guides are placed at the surface of the zinc bath to create an upwardly flow of dross-free molten zinc on both sides of the exiting strip material whereby surface quality is improved independent of strip speed.
