METHOD FOR ELECTROSLAG PRODUCTION OF DIE BLANKS FOR PRESSING-ROLLING LINE FOR PRODUCTION OF RAILWAY WHEELS Russian patent published in 2008 - IPC C22B9/18 B22D23/10 

FIELD: special electric metallurgy, in particular, process used in enterprises for manufacturing and/or utilizing of processing technique for hot plastic working of metals.

SUBSTANCE: method involves providing process in melting space of crystallizer having shape approximating in maximum extent to shape of die blank; melting metal and heating flux using current conductive consumable electrodes made from blank metal and disposed circumferentially within melting space with filling coefficient of at least 0.2, with total weight of electrodes being at least equal to that of blank; conducting process with value of supplied power being constant up to time when shrink hole is removed. Method allows die blanks of desired sizes and shapes to be produced with maximum high metal recovery of 0.8-0.9.

EFFECT: increased efficiency in producing of die blanks for railway wheels.
