摘要： An improved vortex inhibitor for separating slag from molten metal during the discharge of molten metal through a nozzle includes a uniform castable refractory body with a generally tapering shape, a shaft within the body and an elongated sacrificial member. The shaft receives the sacrificial member or a coupling for the sacrificial member. The refractory body and the sacrificial member combination in molten metal has a specific gravity less than the specific gravity of molten metal and is positioned narrow end downward when supported in molten metal. The sacrificial member aligns the vortex inhibitor with the area in which the vortex forms and minimizes interference with the flow through the discharge nozzle.

摘要： 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.
