Abstract

PURPOSE: To omit the slow cooling process and also, to fully carry out the deposition of C, by cooling to a normal temperature after cooling travelling strip heated at a uniform heating temperature to a fixed temperature quickly.
CONSTITUTION: The strip S heated at the soaking temperature of A1 transformation point or less passing through the heating zone 6 and the soaking zone 7, is entered the cooling zone 8 at the continuous annealing of original tin plate. After rapidly cooling the above strip S in the range of 350W450°C at a cooling speed of 40W100°C/sec in the foregoing stage large capacity cooling apparatus 10 at first, the strip S is cooled to a normal temperature at an optional speed continuously. Deposition of C is accelerated and C is sufficiently deposited in the cooling process to a constant temperature by forced cooling in the cooling pattern. Further, annealing line is shortened by omitting the slow cooling process.
