PRODUCTION OF UNRESTRICTEDLY LONG BAR FROM DISTILLED CALCIUM

摘要

FIELD: process engineering.SUBSTANCE: proposed process comprises loading calcium into mould container and compaction with welding of loaded calcium. Uniform mechanical properties without localised arc zone at whatever section of finished article are ensured by loading said calcium in said container of arbitrary shape and size with pre-compaction by crush seal, pressing at the rate of not over 5 mm/s with welding of consecutively loaded portions with press residue height not exceeding 0.2 diameter of the container. To facilitate ductility of finished bar, tool may be heated to 0.45 of calcium melting point, not over.EFFECT: higher ductility of bar.3 cl, 3 ex
