SPRAY CASTING DEVICE OF ALLOY INGOT

摘要

PURPOSE: A spray casting device of an alloy ingot is provided to fabricate a large-diameter alloy article by enlarging a stacking area of an alloy molten metal spray through rotating a gas spraying device about a spraying chamber. CONSTITUTION: A spray casting device of an alloy ingot includes a tundish(110), a gas spraying device(120), a substrate(141), a substrate driving shaft(150), a substrate driving section(160), and a spraying chamber(180). A spraying chamber rotating device(170) is installed in the spraying chamber(180) so as to rotate the tundish(100) and the gas spraying device(120) about the spraying chamber(180). The spraying chamber rotating device(170) is coupled to a rotating shaft connected to a reduction gear, which is engaged with a driving gear connected to a driving motor.
