<div style="font-size:12px;font-family:宋體;font-weight:400;color:#000000;font-style:normal;"> 目前國內(nèi)鐵精粉市場還在弱勢下跌，噸價跌幅為20元。商家反饋，鋼材價格持續(xù)下跌，使得市場人士對鐵礦石后市“更加悲觀”，鋼廠的鐵精粉采購，也是以保持合理消耗量為原則，“不敢盲目擴大采購量”。 </div> <div style="font-size:12px;font-family:宋體;font-weight:400;color:#000000;font-style:normal;"> 由于鐵精粉市場持續(xù)低迷，精選企業(yè)的生產(chǎn)積極性也不高，部分廠家已經(jīng)停產(chǎn)。 </div> <div style="font-size:12px;font-family:宋體;font-weight:400;color:#000000;font-style:normal;"> 至于進(jìn)口礦，目前63.5%品位的印度粉礦的報價在每噸176美元左右，一周下跌1美元。鋼材銷售不暢，鋼廠的資金面不斷收緊，對進(jìn)口礦的采購意愿也不強，國內(nèi)鋼鐵企業(yè)的相關(guān)庫存基本保持在“1個月左右的量上”。 </div> <div style="font-size:12px;font-family:宋體;font-weight:400;color:#000000;font-style:normal;"> 據(jù)相關(guān)機構(gòu)分析師說，受持續(xù)雨水天氣的影響，6月份以來滬上建筑鋼的終端需求萎縮明顯。隨著梅雨季節(jié)的結(jié)束，天氣將出現(xiàn)好轉(zhuǎn)，市場出貨量或?qū)⒊霈F(xiàn)一定的改善，但高溫炎熱天氣對需求也將形成影響，總體需求仍難言樂觀。目前的鋼市是“供強需弱”，上游成本的支撐力也是處于“下跌通道” 內(nèi)，雖然商家心態(tài)在慢慢趨穩(wěn)，但無縫管廠家難有真正的上行動力，鋼市仍以“小幅盤整、消化庫存”為主。 </div></div><p><img src="http://2024aiimg.qy55.com//cjjhb_soft/40/69/202402212004271452.jpg" title="無縫鋼管廠家，定制"><br></p><p><img
