The invention discloses phosphor copper titanium wear resistant cast iron and a preparation method thereof. The phosphor copper titanium wear resistant cast iron comprises the following components in percentage by weight: 2.9-3.3% of C, 1.4-1.7% of Si, 0.6-1% of Mn, 0.4-0.7% of P, 0.5-0.9% of Cu, 0.2-0.16% of Ti, not more than 0.10% of S, and the balance of Fe. The preparation method includes the steps of batching, preheating, smelting, stokehole quick analysis, final deoxidation, inoculation and pouring. The method is simple in smelting process, strictly controls the adding quantities of phosphor, copper and titanium to enable the wear resistance to be higher than HT300-mark cast iron by 1.5 times, can enable the mechanical performance to reach HT250 mark, and in particular, is suitable for casting a coordinate boring machine body. 本发明公开了种磷铜钛耐磨铸铁及其制备方法，所述的磷铜钛耐磨铸铁其成分的重量百分比为C2.9～3.3%、Si1.4～1.7%、Mn0.6～1%、P0.4～0.7%、Cu0.5～0.9%、Ti0.2～0.16%、S≤0.10%，余量为Fe。所述的制备方法包括配料、预热、熔炼、炉前快速分析、终脱氧、孕育处理、浇注。该方法熔炼工艺简单，通过严格控制磷、铜和钛的加入
