MOLD FOR CONTINUOUS CASTING

摘要

PURPOSE:To decrease the induction losses of magnetic fluxes penetrating through mold walls under electromagnetic agitation and to reduce equipment and running costs by constituting four faces of mold walls of composite plates wherein thin walled copper plates and non-magnetic stainless steel provided with cooling water passages are welded by pressure. CONSTITUTION:Four faces of mold walls 10 are constituted respectively of composite plates wherein copper or copper alloys 11 of <=10mm. thickness and non- magnetic stainless steel plates 12 of >=20mm. thickness are welded by pressure. Plural cooling water passages 15 are provided on the side of the plates 12 nearer than the press-welded surfaces 13. Here, the mold is constituted by using the composite plates satisfying t<=p<=2t and 0.5t<=s<=3t when the thickness of the copper or copper alloy plates 11 is 3-7mm. and the width in the press-welded parts between the passages 15 on the surfaces 13 is defined as (p) and the width of the passages 15 as (s).
