              耐磨高鉻錘頭硬度越高越好嗎

              高鉻耐磨錘頭是需要根據破碎機和制砂機等款式的破碎機械的內部結構情況來選擇,不同的破碎設備的規格都是不一樣的,需要的錘頭和錘頭的性能也是不一樣的。高鉻耐磨錘頭的硬度高,是一種優質的耐磨材料,在有支持錘架的細碎機和反擊式破碎機上得到了廣泛應用,但高鉻合金韌性較差,在沒有錘架支撐的情況下容易發生斷裂。

              硬度是影響高鉻耐磨錘頭耐磨性的重要因素,一般情況下,耐磨錘頭的硬度高于磨料硬度的0.8倍以上,以獲得較好的耐磨性。此硬度是指耐磨錘頭工作面在磨損后的硬度,而非磨損前的初始硬度。當金屬的高硬度Hu超過0.8Ha時,金屬表面開始變得有可能使磨料尖角變鈍,因而材料對磨料的磨損變成“軟”磨料磨損,其相對耐磨性b就開始超過材料在硬磨料上測定的數值β。但高鉻耐磨錘頭廠家說耐磨錘頭的硬度并非越高越好,有時過髙的硬度易致顯微的裂紋,所以適當的硬度才是發揮錘頭性能的關鍵所在。
