US 2020/0156130 A1 · ROLLER FRAMEWORK HAVING A FRAMEWORK COOLER FOR COOLING A STEEL BAND

Abstract

A framework cooler (20) for cooling a steel strip (50), installed in a roller framework (11), the framework being in place of the work rolls (5) and the associated installation pieces (5a and 5b). For this purpose, the framework cooler (20) is sized such that it can be installed into the roller framework (11) through the operator-side roller stands (1) of the roller framework (11). The framework cooler (20) includes a lower water tank (21b) and an upper water tank (21a), each having a connection (22) for a coolant, and a plurality of cooling nozzles (23), or cooling tubes (23a) arranged in the depth direction (T) of the framework cooler (20) or at least one cooling slot (24) extending in the depth direction (T) of the framework cooler (20). The lower and the upper water tanks (21b and 21a) can be thereby supplied with coolant by the respective connection (22). The bottom side of the steel strip (50) can be cooled by the cooling nozzles (23) or cooling tubes (23a) or the cooling slot (24) of the lower water tank (21b). The top side of the steel strip (50) can be cooled by the cooling nozzles (23) or cooling tubes (23a) or the cooling slot (24) of the upper water tank (21a).

Dependent claims

A roll stand comprising an operator-side roller housing and a drive-side roller housing;

wherein there are no working rollers and no chocks for the working rollers disposed in the roll stand;
the roll stand has a stand cooler for cooling a steel strip that is being advanced past the roll stand;
the stand cooler is dimensioned such that the stand cooler can be installed in the roll stand through the operator-side roller housing of the roll stand;
the stand cooler comprises a lower coolant tank and an upper coolant tank above the lower coolant tank;
each of the lower coolant water tank and the upper coolant tank having a connector for supplying a coolant to the respective tank;
a plurality of cooling nozzles, or of cooling pipes that disposed in a depth direction of the stand cooler, or at least one cooling slot that runs in the depth direction of the stand cooler, such that the lower and the upper coolant tanks may be supplied with coolant by the respective connector, to each tank;
and
the cooling nozzles, or the cooling pipes or the cooling slot from the lower coolant tank being operative for providing coolant to the lower side of the steel strip for cooling the steel strip;
and the cooling nozzles, or the cooling pipes, or the cooling slot from the upper coolant tank being operative for providing coolant to the upper side of the steel strip for cooling the steel strip.
