Abstract
A method of molten metal continuous casting utilizing an impact pad having a non-wavy spherical top in the tundish that is impacted by the stream of molten metal entering into the tundish wherein the flow of molten metal within the tundish is optimized to improve flow patterns, reduce dead zone areas, prevent splashing while filling the empty tundish, and eliminating the open “red” eye forming in the molten metal surface layer.
Claims2
A method of continuous casting molten metal utilizing a tundish provided with an impact pad having a non-wavy spherical top impact surface without any surrounding sidewalls or weirs, comprising the steps of:
- pouring the molten metal from a ladle downwardly into the tundish, at the bottom of which is located the impact pad with the non-wavy spherical top impact surface without any surrounding sidewalls or weirs restricting the flow inside the tundish;
- the total volume molten metal flowing into the tundish initially impact the non-wavy spherical top of the impact pad and accelerating in a horizontal direction as the height of molten metal in the tundish rises, and wherein the total volume of molten metal flowing into the tundish and impacting the non-wavy spherical top of the impact pad is thereby optimized in terms of higher average molten metal retention time;
- and
- opening tundish discharge nozzles after reaching the desired height of molten metal in the tundish, and the molten metal leaves the tundish through the tundish nozzles to a next continuous casting equipment.
