PURPOSE: A multistage type ferro alloy charging device is provided which is capable of flexibly controlling the charging amount of ferro alloy depending on the operation circumstances of converter. CONSTITUTION: The multistage type ferro alloy charging device comprises a metal case body(12) formed in a cylindrical shape; an inner skirt(14) and an outer skirt(16) integrally formed with being parallel to each other in the lower part of the metal case body; a projected block(18) projectingly installed to the outer side of the metal case body on the boundary part, between the outer skirt and the lower part of the metal case body; a support ring plate(20) integrally formed on the lowermost part of the outer skirt; a plurality of supports(22) fixed to the upper part of the metal case body in a central direction of the metal case body; a hollow rod(24) fixed to the center to which the front end of the supports are collected; a core rod(26) which is slid into the lower part of the hollow rod, and at the middle part of which a bell gate(28) is integrally formed; a pusher ring plate(30) integrally formed on the outer wall of the core rod; buckets which are consisted of a plurality of inserting grooves formed so that a pusher is installed at the inner skirt and outer skirt, and which are stacked in multistage.
