球磨機(jī)襯板材料的研究進(jìn)展編輯機(jī)械磨損涉及的方面很多，其中磨料磨損占全部工業(yè)磨損的50%以上。德國(guó)、英國(guó)等國(guó)家每年因磨料磨損而造成的損失達(dá)數(shù)十億美元，澳大利亞的礦產(chǎn)業(yè)每年因磨料磨損的損失占礦產(chǎn)品銷(xiāo)售額的2%。而磨料磨損中，球磨機(jī)襯板的磨損占了相當(dāng)比重。解決途徑有兩個(gè)方面：一是從材料方面來(lái)提高材料的耐磨性；二是從工藝方面來(lái)改善磨損的環(huán)境。研究主要從材料方面來(lái)闡述。[1]傳統(tǒng)材料ZGMn13用作球磨機(jī)襯板是不恰當(dāng)?shù)腪GMn13屬高錳鋼，是由英國(guó)人Hadfild于1882年發(fā)明的，它是在鋼中加入13%左右的Mn元素，利用Mn元素使鋼S曲線的“鼻尖”右移及Ms、Mf線下移的特性，通過(guò)1000~1050℃長(zhǎng)時(shí)間保溫后強(qiáng)制冷卻而獲得的全奧氏體組織，這種全奧氏體組織具有加工硬化的性能。它用作球磨機(jī)襯板，旨在通過(guò)磨球及磨料對(duì)襯板的撞擊來(lái)達(dá)到其加工硬化的效果。然而，在球磨機(jī)的工作過(guò)程中，磨球及磨料隨著筒體的轉(zhuǎn)動(dòng)而被帶到高處后呈瀑布狀拋下。從高處瀉落的磨球和磨料只對(duì)料堆根部的磨球及磨料進(jìn)行直接沖擊，而對(duì)襯板則是通過(guò)磨球及磨料堆積層進(jìn)行間接沖擊，這樣，沖擊的強(qiáng)度較小，加工硬化的效果不。實(shí)踐證明，在電廠的磨煤機(jī)中，奧氏體高錳鋼加工硬化的硬度在HB230~250之間。
