Abstract
A horizontal continuous casting apparatus comprises, in one aspect, a tundish in which a molten metal material is stored, a mold assembly connected air-tightly to the tundish for casting a round billet, and an extraction device disposed on a downstream side of the mold assembly for forming a billet having a predetermined shape from the round billet fed from the mold assembly. The extraction device comprising a plurality of formation roll units arranged along a casting direction of the round billet and the formation roll units are composed of horizontal circular roll pairs, press units for pressing the roll pairs against the round billet and drive units for driving the roll pairs.
Claims22
A horizontal continuous casting apparatus, comprising:
- a tundish in which a molten metal material is stored;
- a mold assembly connected air-tightly to the tundish for casting an initial billet having a substantially round cross section;
- and
- an extraction means disposed on a downstream side of the mold assembly for forming a billet having a predetermined shape from the initial billet fed from the mold assembly, said extraction means comprising a plurality of formation roll means arranged along a casting direction of the initial billet, said formation roll means being composed of horizontal circular roll pairs, press means for pressing the roll pairs against the initial billet and drive means for driving the roll pairs.
A horizontal continuous casting method performed using a tundish in which a molten metal is stored and having a mold assembly air-tightly connected to the tundish, said method comprising the steps of:
- feeding a molten metal to the mold assembly from the tundish;
- molding a billet in the mold assembly so as to cast a billet having a substantially circular cross section;
- and
- press forming the billet drawn from the mold assembly so as to have a predetermined thin plate-like thickness, said press forming step being carried out in a plurality of stages along a billet casting direction towards a downstream side thereof.
