DEVELOPMENT OF DESIGNS AND METHODS FOR CALCULATING THE EQUIPMENT OF FILLING CHAMBERS OF TUNDISH OF CONTINUOUS CASTING MACHINES
The work considers the design of the equipment of the filling chambers of the tundish (TS) of the continuous casting machine (CCM). The equipment operates in the system: tundish - mold of CCM. TS filling chamber equipment designs have been created to ensure the efficient use of flooded steel jets guided through the filling hole to the mold. Development of structures and methods of structural analysis of pc filling chamber equipment in order to reduce the load acting on the stop of the spill hole, to create conditions for the rational direction of movement of steel sweats into the filling hole in the mold. For the first time, the design scheme of the threshold equipment with spatially oriented holes and the stopper of the filling hole working together in the filling chamber is presented. Result: the paper presents the basic principles of building structures for filling chambers of intermediate buckets, developed taking into account the joint operation of the entire set of PC camera equipment and the specifics of the mold. The designs and methods of calculating the equipment of filling chambers presented in the work make it possible to ensure a rational choice of tundish and equipment for directing liquid metal to the mold for the entire fleet of varietal and slab CCM with a different number of streams.
