FIELD: metallurgy. ^ SUBSTANCE: melt at temperature 200-700C over line of liquidus is poured into a lined and heated casting mould rotating at continuous speed. The casting mould is rotated at values of gravitation ratio in peripheral part of the mould from 50 to 300. Upon filling the mould with melt and distributing it in mould, volume of melt is cooled at rate not more, than 1C/sec. Processes of crystallisation in power field are completed before melt reaches temperature of crystallisation beginning under natural conditions. Rotation of a centrifuge is stopped upon cast cooling in the mould. ^ EFFECT: production of casts of metals and alloys of high quality with super-dispersed structure. ^ 6 dwg, 2 tbl |
