The invention relates to a carbonitriding facility (IC) which includes: a heating chamber (CC), for heating at least one steel part (PA) to a first temperature, in the presence of a neutral gas and under a selected pressure; a first enriching chamber (CE1) for enriching the heated part with nitrogen, by nitriding same in a-phase at a second temperature no higher than the first temperature; a second enriching chamber (CE2) for enriching the nitrogen-enriched part with carbon, by carburising same at a third temperature higher than the second temperature; a quench chamber (CT) for quenching the nitrogen- and carbon-enriched part under pressure; a transfer airlock (ST) communicating with the chambers and suitable for temporarily receiving the part in a controlled atmosphere; and transfer means (MT) for transfer-ring the part from one chamber to another chamber via the transfer airlock (ST).

A railless billet electric induction heating apparatus and method is provided where billets are continuously or statically heated by induction by moving the billets without billet support rails through an induction coil supplied with alternating current power when the billets are in direct sliding contact with the interior surface of a clay graphite billet slider disposed within the induction coil. The clay graphite billet slider can also provide thermal insulation between the induction coil and the clay graphite billet slider to eliminate the requirement for a separate induction coil refractory.

A churning and stoking ram for a furnace is disclosed. The churning and stoking ram includes a frame disposed externally of the furnace, where the stoking ram is mounted on the frame. The stoking ram is positionable relative to the furnace between an external position and an internal position, and is rotatable about a central longitudinal axis of the stoking ram. The stoking ram further includes a churning device positionable relative to the stoking ram between a retracted position and an extended position, a first actuator mounted on the frame to position the stoking ram between the external and internal positions, a second actuator to position the churning device between the retracted and extended positions, and a third actuator to rotate the stoking ram and the churning device associated therewith.
