Rinsing gas device in metallurgical vessel

摘要

Rinsing gas device for a metallurgical vessel consists of a rinsing plate built between the refractory bricks in the bottom or side wall of the vessel. The plate is made of two metal sheets welded together with spacer ribs to form several channels which are fed from a distributor into which the gas conduit is located. - Pref. distributor is made of a tube which is transverse to the channels and has a slit which enables a gas tight joint to be produced between distributor and rinsing plate. The thickness of the channel is constant and max. 1.5mm. The plate height corresponds to the height of the erosion bricks with the distributor being located in the second row of bricks. Each plate is individually regulated for flow. Alternatively the plate can be made of several tubes welded to the distributor with flattened upper longitudinal sections.
