FIELD: process engineering.
SUBSTANCE: invention relates to metallurgy. Dummy bar head compaction system comprises flat elastic sealing element 6 and sealing plate 7 to lock the latter at dummy bar head. Sealing element extends on all side from sealing plate 7 with geometry approximating to casing mould profile cross-section. Sealing plate consists of two halves 7a, 7b located in one plane to allow the plate to displace towards mould center by amount defining taper function of mould 3. On fitting dummy bar head in casing mould, mould inclination is compensated by compaction of sealing plate unless spacing between plate and mould is equal on all sides.
EFFECT: complete sealing in casting large-size billets.
