Strip Casting

Strip Casting is a technology that process of supplying hot metal from ladle and tundish, rapidly solidifying through casting rolls, reducing thickness through rolling mill, cooling and winding up the coil are carried out continuously.

Speed and quantity of hot metal injected to casting rolls give a very important influence to the state of solidification, and the nozzle with optimum shape and size (SEN) supplies hot metal stably and uniformly.
Cooling capacity is important in casting rolls to form thin casting pieces by solidifying hot metal of high temperature rapidly. Productivity is maximized through innovative cooling method of casting rolls and perfect control of cooling water quantity.

The slap of high temperature solidified through casting rolls enters into the rolling mill straight, and is rolled in proper form and thickness to form the thin steel sheet.
