ABSTRACT:
Provided is a crystalliser holding device for billets, blooms and slabs production plants that has a high constructive simplicity, a significantly reduced overall weight and that reduces substantially to zero the need for maintenance. The crystalliser holding device of the invention, in addition to efficaciously guaranteeing the transfer toward the exterior of the heat of the liquid steel introduced into the tubular crystalliser contained therein, also provides a separate circuit for cooling the continuous ingot exiting the crystalliser and the rollers at the foot. It also permits an easy and rapid replacement in the oscillating table in which it is housed.
