國內(nèi)硅錳市場處于弱勢運行，零售價格階梯下調(diào)，但南北價格略明顯，南方廠家較難低價供應市場，南北有200余元價差存在，同樣低價大部分出在中小資金偏緊廠家，部分大廠仍在執(zhí)行訂單，并未有新價格公布，錳礦1月外盤價格下調(diào)幅度較大，鍍鋅扁鋼市場弱勢情緒增加，廠家也同樣在加快消耗手中高價錳礦庫存，為防止后期虧損的擴大。 </p> <p> 本周，國內(nèi)硅鐵市場維持弱勢，主產(chǎn)區(qū)報價繼續(xù)下滑，鍍鋅扁鋼市場成交價格低探。從目前市場現(xiàn)狀來看，主產(chǎn)區(qū)廠家訂單結(jié)束，庫存開始逐步累積，部分廠家?guī)齑嬉琅f處于低位，隨著鍍鋅扁鋼市場可流通的現(xiàn)貨增多，下游客戶采購越來越謹慎，買漲不買跌心態(tài)顯現(xiàn)，整體成交量少，觀望為主。11月粗鋼產(chǎn)量7760萬噸，較10月8260萬噸產(chǎn)量下降6%，折算硅鐵需求量減少2萬噸，而硅鐵市場供應尚維持在高位，11月硅鐵產(chǎn)量在49.5萬噸左右，從當前的開工情況來測算，12月硅鐵產(chǎn)量在48.5萬噸左右。
