Apparatus for cooling steel belt

摘要

A steel belt cooling apparatus is provided on both sides of a running steel belt. Each cooling apparatus has a gas cushion type nozzle essentially consisting of two slit nozzles which extend in the lateral direction of the steel belt with each nozzle head inclined inwardly toward the other and a flat plate between the slit nozzles. On the flat plate are a plurality of ribs extending from the slit nozzle on the upstream side to the slit nozzle on the downstream side and arranged in parallel across the width of the steel belt. The ribs may be provided such that the height of the tips of the ribs may be the same as the height of the tips of the gas cushion nozzle.
