Tan dish with filter module

The filtering system in continuous metal casting tundishes addresses the inefficiencies of existing designs by ensuring a significant portion of molten metal flows through the filter unit and provides a bypass path to prevent overflow, effectively removing debris and maintaining stable casting operations.

Abstract

The filter module (1) of the filtering system for the tundish (10) comprises a filter unit (1f) with a channel (1c) extending from a channel inlet to a channel outlet, and a wall module (2) with a wall defining an opening (2o) extending from the floor (10f) over an opening height (h2). A bypass passage (2b) is defined between the wall module (2) and the filter module (1) with a maximum width (t12), whereby the molten metal can only flow from the inlet portion to the outlet portion by either passing through the channel of the filter unit (1f) or by flowing through the bypass passage (2b). The wall module comprises a wall ledge (2L) with a width (t2L). The filter module (1) further comprises a filter ledge (1L) with a width (t1L) and offset vertically with respect to the wall ledge (2L) to form a baffle.
