Liquid-cooled mould for continuous casting of metals

摘要

The liquid-cooled mold for continuous casting of metals, comprises mold plates (2) made of copper or copper alloy, and adapter plates (3), at which the mold plates are fastened by fastening bolts. The mold plates are coupled to the fastening bolts over supporting plates (19) arranged in its head- (20) and foot areas (21) with the adapter plates. The mold plates are a component of slab molds or thin-slab molds, or a component of a broad side plate (1) of a beam blank mold. The supporting plate engages with projections in the head- and foot-sides recesses of the adapter plates. The liquid-cooled mold for continuous casting of metals, comprises mold plates (2) made of copper or copper alloy, and adapter plates (3), at which the mold plates are fastened by fastening bolts. The mold plates are coupled to the fastening bolts over supporting plates (19) arranged in its head- (20) and foot areas (21) with the adapter plates. The mold plates are a component of slab molds or thin-slab molds, or a component of a broad side plate (1) of a beam blank mold. The supporting plate engages with projections in the head- and foot-sides recesses of the adapter plates and is coupled with the mold plates over a groove/spring formation. The mold plates have longitudinal grooves, in which the supporting plate engages with edge-sided springs, in the head areas and in the foot areas. The longitudinal grooves are limited by marginal beads of the mold plates and also by bars formed at its rear side. The bars obliquely run out in the area of the lateral front surfaces of the mold plates to their rear side. The springs are formed at the supporting plates on the basis of internal cavities of the supporting plate. The internal cavities overlap the bars at the mold plates, and the strips adjacent to the bars at the adapter plate. The mold plate has a middle bar, a shank adjacent to the middle bar and an edge-side flange adjacent to the shank. Circular transitions present itself between the oblique shank and the edge-side flange. The mold plate has slide strips on its rear side in the area of the transition, and retaining strips arranged at a cooling side of the adapter plate in the area of throats between the flange and the shank, where the slide strips and the retaining strips extend itself in the casting direction. The slide strips are a one-piece component of the mold plates. The retaining strips are detachably assigned in grooves of the cooling side of the adapter plate. The supporting plates are provided at the front-side of the springs with chamfers. The casting side of the mold plate is provided in the foot area with the chamfers.
