Abstract (en)
To overcome various problems associated with moulding of steel, the moulds (5) are shot peened in between casts using an air-blast system which incorporates a compressor (4), a shot recovery and supply system (2), a dust collector and control section (3, 3 min ) and a peening/cleaning station (1) which has a nozzle assembly (9) arranged to traverse the length of a mould (5) whilst rotating and simultaneously firing shot at the interior mould surfaces to achieve a peening effect.
