Abstract
It is important to improve the plane view patterns of plates, in order to increase the yield of steel plates. For this purpose, edging method is examined by a laboratory test using lead plates, so that optimum edging condition is established, and the results are applied to actual plate rolling.
The results are as follows:
(1) By the edging method, plane view patterns are improved with the yield increase of about 2%.
(2) The edging method is more effective when both top-bottom edging and side edging are carried out.
(3) The edging method is also effective to diminish the side overlap of heavy plates.
