Abstract
A method and apparatus is disclosed to improve the metal yield by adjusting the tilt angle of a tilting vessel having a submerged tap hole. The tilt angle is adjusted in response to parameters inherent in the pouring process, i.e. the proximity of the vessel contents to the vessel lip, the age of the tap hole, the liquid head over the tap hole, etc. Additionally, methods are disclosed to enhance the metal yield by advancing or moving back the furnace without knowledge of the tilt angle. Moreover, such methods and apparatus can be implemented through the use of computer based algorithms. The methods can also be used to archive pouring parameter information for future uses such as training and reviewing.
