Abstract:
一种大型球磨机衬板及其制备方法,属于耐磨材料技术领域。首先将废钢、增碳剂、铬铁、氮化铬铁、铌铁、硼铁、锰铁和硅铁在电炉内混合加热熔化,钢水温度达到1580~1600℃时,加入铝脱氧,将炉内钢水的化学组成及其质量分数调整至0.70~0.85%C, 1.8~2.0%Cr, 0.05~0.09%N, 0.12~0.18%Nb, 0.6~1.0%Mn, 0.25~0.60%Si, 0.004~0.008%B, 0.05~0.08%Al, < 0.04%S, < 0.05%P, 余量为Fe和不可避免的微量杂质元素,然后对钢水进行微合金化处理,并浇注成衬板,衬板热处理后具有硬度高和耐磨性好等特点,推广应用具有良好的效果。
