Abstract
PURPOSE: To perform salt bath processing, eliminate chamber phenomenon and improve yield by evenly cooling the strip down to about the same temperature as molten salt bath temperature after heat treatment.
CONSTITUTION: A stainless steel strip 1 which has been subjected to heat treatment is led evenly to a cooling unit. Cold air is then injected at an injection angle of 60° in the advance direction of the strip 1 by air injection pipes 5A, 5B only to the central part width B of 20W25% of the plate width L. If at this time, both end parts are naturally cooled, the strip 1 cools evenly to the same temperature as the molten metal bath temperature of 350W450°C. Thence, it is dipped in that state into the molten salt bath cell of 350W450°C, whereby it is subjected to the molten salt bath processing.
