Abstract
A mold for the continuous casting of blooms, slabs or billets is provided with a mold tube (2) and a supporting shell (4) surrounding said mold tube. The mold tube (2) is supported by support profiles (15) on the supporting shell (4) extending in its longitudinal direction and distributed over the periphery and is positively connected thereto via connecting profiles (20) extending in the longitudinal direction. The connecting profiles (20) are respectively configured as profile strips (21, 22) outwardly projecting from the outer periphery of the mold tube (2) and inwardly projecting from the inner periphery of the supporting shell (4), which engage in one another such that in the peripheral direction of the mold a clearance is present. As a result, the stresses, permanent deformation and fatigue cracks produced by the thermal expansion in the mold tube are substantially avoided.
