MACHINE FOR FORMING METAL BARS Russian patent published in 2016 - IPC B22D5/00 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy and can be used in production of ingots from precious metals weighin from 50 g to 50 kg. On loading position (101) of machine, solid metal is loaded into mould from pouring device "A" and chemical additive, acting on crystalline structure of material from dosing device "B". Mould is closed with covers and moved by pusher into next positions. On position of melting (102) metal in said mould is fused in melting furnace. Chemical additive further added to liquid metal from dosing device "C". Position of hardening (104) metal in mould comprises a trough or cooling bath. Position of cooling (105) includes means for cooling ingot, bath with cooling fluid for fast cooling and means for extracting and collecting cooled ingots. Unloading position (106) comprises unloading of moulds with ingots or empty moulds after extraction fast-cooled ingots.

EFFECT: providing accurate dimensions and weight of ingots and improvement of their metallographic structure.
