FIELD: metallurgy.
SUBSTANCE: invention relates to metallurgy. Mould has cavity 2 which has a pouring opening for liquid metal and an outlet opening for a cast strand. Cross-section of mould is at least partially is formed with profiled circuit 8 of side walls 5.5', 6.6', which continues in direction of casting. Circuit 8 is in form of a wavy profile, which has a number of channels (9), extending in parallel from filling hole to outlet of cavity of mould.
EFFECT: ratio of inner perimeter of mould cavity to width W of channel is greater than 30, and width W of channel ranges from 1,5 mm to 30 mm.
