CAST STEEL RAILWAY WHEEL HAVING MARKS AND METHOD FOR CASTING RAILWAY WHEEL HAVING MARKS

摘要

The invention relates to the foundry. Casting of a railway wheel is carried out in moulds from cold-hardening mixtures or produced by vacuum-film method Dies having marks are fixed on the casting model bottom or casting top in the casting model areas. The casting model is placed in moulding position, and compaction of moulding sand with transfer of marks is carried out on the mould working surface. The marks thus provided on the cast steel have clear contours and remain visible during the service life the railroad wheel.
