A continuous casting machine is a device used to continuously cast molten steel into billets during the steelmaking process. During the steelmaking process, after the molten steel is smelted from the converter or electric furnace, it needs to be cast and formed by a continuous casting machine to produce billets of various specifications. The application of continuous casting machines has greatly improved the production efficiency of steelmaking, reduced production costs, and improved the quality of billets.
Continuous Casting
The main components of a continuous casting machine include intermediate frequency furnace:
- Ladle car: equipment for transporting molten steel from a converter or electric furnace to a continuous casting machine.
- Tundish: a container for temporarily storing molten steel and performing degassing, desulfurization and other treatments.
- Crystallizer: a copper water-cooling device where molten steel is cooled and solidified into billets.
- Vibration device: a device that vibrates the billet to form a dense grain structure in the crystallizer.
- Billet straightening machine: a device that pulls the solidified billet out of the crystallizer and straightens it.
- Cutting equipment: a device that cuts the billet into a predetermined length.
- Conveyor roller: equipment that transports the billet to the next processing link.
The following points should be noted during the use of the continuous casting machine:
- Ensure that the temperature and composition of the molten steel meet the continuous casting requirements to avoid affecting the quality of the billet.
- Control the vibration frequency and amplitude of the crystallizer to obtain the best grain structure and mechanical properties.
- Regularly check and maintain the various components of the continuous casting machine to ensure the normal operation of the equipment.
- Comply with operating procedures to ensure safe production.
The continuous casting machine in steelmaking is a key equipment to improve production efficiency, reduce costs and improve the quality of billets. By adopting advanced continuous casting technology, the competitiveness of steel mills can be improved and high-quality raw materials can be provided for downstream manufacturing industries.
