連続鋳造における伝熱現象の数値解析について

The continuous casting of steel is rapidly expanding its scope of influence in the field of steel making, because the process is superior to the conventional ingot making process from the view point of the product quality, working environment, and automation.
The main problem of continuous casting is how to control heat transfer phenomena skillfully.
Therefore, this report describes the results which were calculated by mathematical models of the heat transfer in each step from the tapping of steel to the transfer table as described below:
(1) The relation between the elapsed time and the temperature of molten steel in the ladle.
(2) The relation between the elapsed time and the temperature of molten steel in the tundish.
(3) Temperature distributions of the billet in the mold, and the secondary cooling and air cooling zones.
(4) Temperature distribution of the billet in the soaking furnace.
(5) Temperature drop of the billet due to in-line reduction.
(6) Temperature distribution of the billet on the transfer table.
In these cases, calculations were performed sequentialy by algebraic equations by the use of finite difference techniques.
