FIELD: metallurgy.
SUBSTANCE: this billet features cylindrical shape with ends shaped to spherical convex surfaces and axial 100±5.0 mm diameter bore. Billet bottom end features spherical convex surface on length Lb.e.s.=0.12Lbil.±15, with end diameter Db.e.s.=0.92Dbil.±5.0. Biller outer surface is conjugated with diameter of the end with radius Rb.e.s.=0.93Rbil.±5.0. Billet shrinkage end features spherical convex surface on length Ls.e.s.=0.08Lbil.±10 with end diameter Ds.e.s.=0.97Dbil.±5.0. Biller outer surface is conjugated with diameter of the end with radius Rs.e.s.=0.96Rbil.±5.0, where Lbil.=1630±50 is billet length, mm; Dbil.=630±10 is billet diameter, mm; Rbil. is billet radius, mm.
EFFECT: lower metal input, higher precision of sizes, increased length of pipes.
