摘要： Ingot mold head boxes may be lined by inserting a first former therein, to leave an annular gap between itself and the head box, placing hot-topping composition in the gap, and by passing a second former into the gap, and thereby squeezing the hot-topping material onto and against the head-box walls. The two formers are then removed.
