Abstract

PURPOSE:To make the easy and inexpensive mass production of hollow stock having good quality by supplying continuously a molten metal into a mold while inserting a core material penetrating through a tundish connected to the mold then removing the core material from the billet. CONSTITUTION:The molten metal 9 is continuously supplied around the core material 8 at the same instant while the core material 8 is inserted through the tundish 7 connected with the mold 2 open at both ends via refractories 6 from above and after the molten metal is solidified, the core material 8 is removed from the billet 8. Either of a refractory coating layer 12 compounded with an inorg. binder or refractory coating layer 13 compounded with the org. binder is coated on the surface of the material 8. Even the seamless steel pipe stock for an oil well pipe or the like having good quality is thus formed extremely easily and inexpensively.
