FIELD: metallurgy.
SUBSTANCE: disclosed installation consists of casting tank with two rows of ports and fissured moving grate and of crystalliser with two pairs of vertical walls. The first pair of walls of the crystalliser is made in form of heat pipes with heating and cooling devices; this pair is designed to perform reciprocal motions, while the second pair is designed to perform rotating motions and converge; it has expanded upper and vertical lower sections. In the middle part of the casting tank there is located an additional tank with a stop and an immersing casting cup. Metal in amorphous state comes to expanded sections of crystalliser walls from the casting tank overcooled below temperature of crystallisation. Simultaneously overheated metal comes from the additional tank to the centre of the crystalliser. Separate supply of the same metal with different temperature into the crystalliser creates conditions for producing nano-crystal structure of the billet.
EFFECT: increased efficiency of production of nano-crystallised billets.
