Tipping point

of a crucible furnace refers to the pivot point of the crucible furnace, around which the furnace is tipped. The casting spout length and the relevant tipping point must be optimised, depending on the use of the furnace and the device employed to accept the melt. An optimum pivot point for all applications is the “lower lip” of the casting spout with a relatively long casting spout, in order to provide clearance for ladles in front of the furnace. This arrangement means that the casting stream can be directed accurately, and produces the lowest possible height differences between casting and total emptying.
