Abstract

1,253,134. Quenching metal strip. KAISER ALUMINUM & CHEMICAL CORP. March 20, 1969 [April 8, 1968], No.14780/69. Heading C7N. A apparatus for uniform fast quenching of continuously moving metal strip emerging from a continuous heat treating furnace 20, see Fig. 1, comprises a baffle 34 close to the furnace outlet for directing a straight line relatively thin, non- turbulent curtain of coolant having a substantially uniform cross-section from edge to edge thereof, transverse to the direction of travel of the strip 5 at an angle less than 90 degrees thereto and against at least one side thereof; and at least one gas discharge outlet 26, 33 for directing heated gas against the strip to fully envelop it and preclude atmospheric contact prior to cooling and coolant splash back into the furnace. Both the coolant curtain and the gas preferably overlap the edges of the strip. Further baffles 34 may be provided which face in the opposite direction to those close to the furnace exit the flow of coolant from which acts to retard the original coolant and thus wipe it off the strip.
