style="text-indent:25px">礦山機械開采需要多次進行擊打和切割，所以對機械設備中材料使用的耐磨性要求非常高，還要保證機器工作過程中的磨球不會裂開，這是對礦山機械設備鑄件整體性工藝的要求，從當前我國科學技術和制造業(yè)發(fā)展的實際水平來看，鑄件鑄造想要達到這些要求是沒有很大難度的，而且不久后我們就可以實現完全的自動化生產發(fā)展。隨著科技與經濟的發(fā)展進步，鐵礦開采已經有足夠的資金和技術支持實現更高級的鑄件鑄造，礦山機械設備的使用性能也在不斷提升，在機械設備鑄件鑄造的材料使用上又添加了非錳系列耐磨合金鋼。相比較高錳鋼來說，非錳系列耐磨合金鋼的使用時間較長，使用期間完全不需要擔心斷裂、破損等問題，用非錳系列耐磨合金鋼制造的球磨機，它的使用率和使用時間相比其他材料提升的非一點半點。但是這種材料的工藝處理并不容易，因為一些限制性因素，需要對非錳系列耐磨合金鋼的制造進行優(yōu)化，在關注利用率和使用壽命的同時，還需要提高它的硬度和耐磨性，盡較大努力實現綜合比較佳的效果。蘇州礦山機械制造商</p></p><br
