Verfahren zur Bearbeitung eines Stahlgußstranges

摘要

The invention relates to a method for the production of plates from continuously cast slabs. Immediately after the continuously cast bar has solidified and as soon as its marginal zone has reached a mean temperature of 800 DEG to 1000 DEG C while the core zone is still of higher temperature, a continuously cast bar is shaped in a preliminary one-step shaping process in which primarily the core zone is shaped. After shearing to length, the slabs are cooled, re-heated to rolling temperature and shaped in a multi-step rolling process proper wherein essentially the marginal zones of the slabs are subjected to shaping so that finally a uniform degree of shaping is achieved over the total cross section of the slabs. By this new method it becomes possible to produce plates with a cross section of 50 to 100 mm by using continuously cast slabs whose initial thickness does not exceed 300 mm.
