PURPOSE: An inoculant injection machine for producing cast iron and a furnace for injecting inoculants are provided to improve the yield of spheroidal graphite steel by compensating fading effect when injecting inoculants into molten metal. CONSTITUTION: An inoculant injection machine for producing cast iron comprises a bottom surface(150), a wall(140) erected along the perimeter of the bottom surface to form an inner space accommodating an inoculant(10), a lid(110) formed in the size and shape corresponding to the perimeter at the top of the wall, a first folding unit(115) which connects the wall to one side of the lid in order to prevent the separation between the wall and the lid when opening the lid, and an outlet(120) which is formed by opening one side of the wall to discharge an inoculant outside. |
