Abstract High-speed continuous casting was the premise to make direct rolling or continuous casting and rolling come true, the embody for realizing high-efficiency and green steelmaking production line, and the theme for developing new generation of high-efficiency continuous casting technology. Presently, the most challenge for high-speed continuous casting was the occurrence of breakout and cracks with high frequency. Therefore, to make it come true, the core was the control of homogenous growth of solidifying shell during casting, the most importance was the technology integration of continuous casting mold including flow control, flux type, lubrication, inner shape and cooling system, the key was the steady control of liquid steel level in mold. The transport phenomena in mold with high-speed casting and the related key technologies were presented and discussed.

Key words： high-speed continuous casting continuous casting mold with high-efficiency heat transfer mold flow control mold level control transport phenomena
