■ Mainly　used　as the compound　steel－making　deoxidization agent and alloying agent．
　　■ As an alloy element，silicon manganese can alloy the steel，strengthen the intensity， hardness． malleability， toughness and weavability of the steel，
　　■ Produced from an electric arc furnace of 6300KVA or12500KVA， by reducing the manganese oxide and silicon dioxide of manganese are and silicon ore with carbon．
　　■ Supplied in plastic woven bags of around 1000kg net each． The grain size， chemical composition and packing conditions can be adjusted according to customer' s requirement．
