Tundish barriers containing pressure differential flow increasing devices
First Claim
1. A tundish used to pour molten metals having a bottom and side walls and molten metal entry and exit points which points are separated by a baffle having sides, two faces and an upper and lower half which baffle has its sides positioned between the tundish walls in a position which is transverse to the direction of molten metal flow with the face of the baffle facing the molten metal entry point being its back face and with the face of the baffle facing the molten metal exit point being its front face which baffle has a number of openings extending between its back and front faces and in addition thereto at least one pressure differential flow increasing opening located in the lower half of the baffle which opening has its inlet located in the back face of the baffle which inlet is wider in cross section than the outlet which is located in the front face of the baffle.
