Abstract
Continuing the previous report on 3S, the cold rolled 52S sheet, the manufacturing conditions after hot rolling process of slab, i. e. the direction of cold rolling, the cold reduction and the annealing temperature, are pursued on effect to the directionality of sheet. The results are summaeized as follows:
(1) In this experiment, the ear by deep drawing of 52S sheet is 0°-or 90°-ear in all.
(2) The ear is less than 2% notwithstanding annealing temperature, and this extent of ear is out of question for the using die in production process.
(3) There is not so distinguish difference between the one-way-cold (unidirectional) rolled sheet and the cross way rolled one.
(4) It is not consistent to the previous results that the directionality by means of Knoop ratio is in closed connection with the ear in deep drawing.
