Pig Casting Machine (PCM)

The Pig Casting Machine (PCM) is basically inclined chain conveyor system having a set of overlapping moulds fixed between a power of change which move over a set of stationary rollers. There are two sets of sprockets on either side of the PCM one of which is driven (idle) and the other is driving sprocket. The drive unit consists of an AC or DC motor coupled to a multistage helical reduction gear box, the output shaft of which is connected thru’ coupling to the sprocket shaft supported at end by bearing.

The conveyor moves continuously while the hot metal is poured thru’ the launder from ladle on ladle stand at a synchronised speed with the pouring speed. The synchronised speed is achieved either by VVVF drive in case of AC systems or by thyristor drive in case of DC systems. The stationary guide rollers are fixed on a set of stringer beams and the assemblies are supported by a system of technological structure.
