Abstract
Ingot yield is improved by changing teeming practice to pouring ingot body and hot top by weight rather than by volume to a mark on a hot top casting. Correct weight addition to the ingot hot top is calculated by a computerized weight-loss weigher system using either a value related to ingot mold body size or a precentage of body weight. Calculation is initiated either manually or automatically when hot metal level is detected at the bottom of the hot top casting.
