Study of fluid “Renewal time” for Continuous Casting tundish by Simulation of water model

The tundish is the important metallurgical unit of the continuous castin-g. In order to incressing demand for steel of higher quality, effective mesur-es must be elaborated to remove the large non-metallic inclusions by optimizing fluid flow and renewal time of liquid steel in the tundish, making it possible to raise from steel melts.
The paper presented the influence of liquid debit, teeming spout immer-sed in bath, deep bath, proper dam on the fluid renewal time and flow pattern in the tundish by the experiment of water model. Liquid depth and proper dam of tundish are very effective for renewal time and flow pattern in the tundish.
