Method for treating zinc-containing waste steel by adopting converter full-three-component-removal smelting process

The invention discloses a method for treating zinc-containing waste steel by adopting a converter full-three-component-removal smelting process. The method comprises the following steps that zinc-containing waste steel is added into molten iron for dephosphorization converter smelting, first high-zinc dust is recovered through a dust removal system in the dephosphorization smelting process,and low-zinc semi molten steel is obtained; and the low-zinc semi molten steel is subjected to decarburization converter smelting, first low-zinc dust and second high-zinc dust are recovered through the dustremoval system in the decarburization smelting process, decarburized molten steel is obtained, and treatment of the zinc-containing waste steel is completed. According to the method, the low-zinc semi molten steel smelted and produced by a dephosphorization furnace is mixed into a decarburization furnace for smelting, the zinc content of the produced molten steel is extremely low, and the influence of zinc on the quality
