class="khcont1">　　進(jìn)礦價(jià)小幅下跌，普氏62%品位鐵礦石指數(shù)為每噸1325美元，一周下跌75美元。11月份，進(jìn)鐵礦石達(dá)7784萬(wàn)噸，較10月份上升1000多萬(wàn)噸，同比增長(zhǎng)18%以上，創(chuàng)下歷史新高。臨近年底，海外礦石生產(chǎn)商有主動(dòng)增加量動(dòng)力，估計(jì)進(jìn)礦價(jià)將穩(wěn)中有降。　　人們常以為磁鐵吸附20 精密管材，驗(yàn)證其優(yōu)劣和真?zhèn)?，不吸無(wú)磁，認(rèn)為是好，貨真價(jià)實(shí)；吸者有磁性，則認(rèn)為是冒牌。其實(shí)，這是一種極其片面、不切實(shí)錯(cuò)誤辨別方法。20 精密管種類繁多，常溫下按組織結(jié)構(gòu)可分為幾類：1．奧氏體：如303231310等；2．馬氏體或鐵素體：如430、420、410等；奧氏體是無(wú)磁或弱磁性，馬氏體或鐵素體是有磁性。　　通常作裝飾管板20 精密管多數(shù)是奧氏體304材質(zhì)，一般來(lái)講是無(wú)磁或弱磁，但因冶煉造成化學(xué)成分波動(dòng)或加工狀態(tài)不同也可能現(xiàn)磁性，但這不能認(rèn)為是冒牌或不合格，這是什么因呢。上面提到奧氏體是無(wú)磁或弱磁性，而馬氏體或鐵素體是帶磁性，由于冶煉時(shí)成分偏析或熱處理不當(dāng)，會(huì)造成奧氏體30420 精密管中少量馬氏體或鐵素體組織。　　這樣，30420 精密管中就會(huì)帶有微弱磁性。另外，30420 精密管經(jīng)過(guò)冷加工，組織結(jié)構(gòu)也會(huì)向馬氏體轉(zhuǎn)化，冷加工變形度越大，馬氏體轉(zhuǎn)化越多，鋼磁性也越大。如同一批鋼帶，生產(chǎn)Φ76管，無(wú)明顯磁感，生產(chǎn)Φ5管。因泠彎變形較大磁感就明顯一些，生產(chǎn)方矩形管因變形量比圓管大，特別是折角部分，變形更激烈磁性更明顯。 </div><p><img
