Behavior of Lubrication and Heat Transfer in Mold at High Speed Continuous Casting

In order to cast high quality slabs with high productivity, high speed casting technology has been investigated with a pilot continuous casting machine capable of casting 50 to 100 tons of molten steel. The results can be summarized as follows; (1) High casting speed of 5.0 m/min for low carbon stee...

description In order to cast high quality slabs with high productivity, high speed casting technology has been investigated with a pilot continuous casting machine capable of casting 50 to 100 tons of molten steel. The results can be summarized as follows; (1) High casting speed of 5.0 m/min for low carbon steel has been achieved with low viscosity powder. The powder consumption is small, from 0.1 to 0.2 kg/m2, but stable casting has been conducted. (2) Longitudinal crack has been occured even if for low carbon steel at up to 4.0 m/min. When the heat flux in mold increased critical value, longitudinal crack occured. (3) The control of the heat fluxes through the mold can be achieved by using the powder with appropriate properties.
