METHOD OF PRODUCING SET OF CASTING MAGNETIC VARIOUS-TYPE RODS Russian patent published in 2011 - IPC B22C9/10 

FIELD: process engineering.

SUBSTANCE: electromagnetic system consisting of electrical coil 1, core 2 and pole tips 3, 4, is arranged in mold-shaping fixture 5. To shape working surface of each rod, appropriate fixture 5 with identical unified length of shaping surface is used, said length exceeding casting length and being equal to distance between pole tips 3, 4. One electromagnetic system is used for all types of rods in a set. Space between pole tips is filled with magnetising loose forming material 8. Forming material 8 is compacted and hardened by magnetic field. Rod is withdrawn from fixture. Arrangement of tips 3, 4 outside forming material layer 8 and casing allows uniform compliance of rod working layer.

EFFECT: uniform compliance of rod working layer.
