FIELD: metallurgy; continuous metal casting machines. ^ SUBSTANCE: the invention is pertaining to the field of metallurgy, in particular, to the roller section of a continuous metal casting machine. The roller section contains the guiding rollers set to the dimension of the cast ingot. The rollers are fixed by their chucks on a support frame. In the frame along the ingot passing section there are holes. The screw rods passing through the holes in the support frame are fixed to the support frame by screw nuts. The rods are tightened by the nuts for formation in them and, therefore, in the support frame of a tension. In the support frame create the stress and strain tensions directed oppositely to the tensions arising during operation. As a result it excludes deformation of the support frame and distortion of the guiding rollers setting on the processing shaft. The invention ensures prevention of a discard by hot cracks, an increase of output of a good product and quality of the metal. ^ EFFECT: the invention ensures prevention of a discard by hot cracks, an increase of output of a good product and quality of the metal. ^ 2 cl, 15 dwg |
