Induction crucible furnace for maintaining or increasing the temperature level of a metal melt, characterized by the feature that the inlet of the melt to the crucible furnace is arranged below the bath level in the furnace.

Continuous-flow heater for molten metals

Preventing work pieces of iron or iron alloys in the form of a line of blocks which are pushed through an induction coil and heated to a forging temperature from sticking together. The surfaces of blocks which touch are subjected to an elevated temperature of heating and pressure due to pushing causing sintering with sticking. The application of a finely-divided material of predominantly iron oxide to the surfaces prevents sticking together of the surfaces when subjected to elevated temperature and pressure.
