Foundry Trade Journal :The Auto Chassis International iron foundry recently commissioned at Le Mans is reputed to be one of the most modern iron foundries in the world, because of the level of technical innovation incorporated.

A melting requirement of 30 tonne an hour is provided by medium frequency melting plants, with two intermediary 10 tonne capacity Auto Pour allowing the simultaneous pouring of two boxes at a time on a Savelli green sand moulding line having double step mould movement 250 x 2 for total of 500 mould/H poured moulds.

The automatic pouring furnaces supplied by Fomet srl, are equipped with the most technically advanced pouring control system yet seen in foundries, which includes metal level control by laser, and a reactive intelligent video camera system to supervise the control of the dosage of molten iron into the moulding boxes. Each furnace is equipped with ‘smart’ automatic inoculation systems for correcting metal composition with in stream inoculation. Each furnace is equipped with a dynamic electronic weighing system which provides continuous management data to measure the amount of metal in the furnace.

The Fomet pouring furnaces are channel induction mains frequency type, incorporating a very high level of thermal insulation along with constructional characteristics and ‘know-how’ covered by patents. The economical air-cooled induction coil (no water) also facilitates both maintenance, and eventual replacement of the inductor.

Italian company Fomet has also supplied an automatic furnace charging system which uses interchangeable three tonne ladles. Each full ladle, after being placed in the charging unit, is raised, tilted and controlled by the management system, to provide a constant feed to the furnace inlet siphon, without interrupting the pouring operation.

The management interface pouring system of the furnace, also exchanges data with the other associated plant. This continually maintains the maximum efficiency of the entire production processes, while indicating any potential problems requiring maintenance intervention.

The entire system is designed to function close to 96% efficiency.

ACI previously chose Fomet equipment for its pouring production in the foundry at La Mans on the DISAMASTIC line.
