Stopper type metering nozzle quick-change casting equipment

Stopper type metering nozzle quick-change casting equipment

Ten years ago, our company took the lead in developing the tundish metering nozzle quick-change patented technology. This technology can greatly extend the functional life of the flow control by multiple times of change of metering nozzle in one-time casting tundish, and then improve the continuous casting time and continuous casting furnaces of tundish, extending the life of tundish to more than 60 hours, thereby improving slab quality and yields, as well as the production efficiency, and reducing refractory consumption and production costs, as well as labor intensity. However, the casting speed changes within a certain range, so it can only be applied to the production of ordinary steel.

The “stopper metering nozzle quick-change casting equipment” researched and developed by our company integrates metering nozzle quick-change technology and stopper flow control technology, which is applied to the production of high quality steel and alloy steel by concentrating its strong points, to achieve stable pull-speed of casters, while extending the life expectancy of tundish up to more than 40 hours. And the stopper metering nozzle quick-change technology significantly improves the quality of slabs and yields, as well as production efficiency, and reduces production costs. The project obtained two utility model patents for stopper type metering nozzle quick-change casting equipment granted by the Intellectual Property Office of the People's Republic of China on February 13, 2008.
