Production system and technology of high-purity manganese-silicon alloy

The invention discloses a production system of high-purity manganese-silicon alloy. The production system comprises a first feeding device, a second feeding device and a submerged arc furnace. The first feeding device and the second feeding device communicate with the submerged arc furnace. The production system further comprises a waste heat tower, a secondary air cylinder, a steam turbine set, acondenser, an oxygen remover, a chimney and a cooling tower. A smoke outlet of the submerged arc furnace, the waste heat tower and the chimney communicate with each other in sequence. An overheater,an evaporator and an economizer are arranged in the waste heat tower in sequence from the inlet to the outlet, and communicate with a steam drum. The overheater, the secondary air cylinder, the steamturbine set, the condenser, the oxygen remover and the economizer communicate with each other in sequence, and a cooling water circulation system of the cooling tower communicates with the condenser.The invention further disclo
