The invention relates to a highly wear-resistant alloy bar. The highly wear-resistant alloy bar consists of the following substances in percentage by mass: 0.3-1.8% of C, 1.8-3.5% of Si, 0.8-2.5% of Ti, 1.3-1.5% of Bi, 0.5-1.5% of Mn, 1.1-1.3% of Cr, 0.1-0.5% of Al, 0.1-0.8% of Cu, 0.5-1.5% of Mg, 0.1-1.1% of Ni, 0.05-0.3% of V, 0.01-1.1% of La, 0.01-1.1% of Re, 0.1-3.5% of Mo, 1.2-3.1% of W, andthe balance Fe containing inevitable impurities. A production technology of the highly wear-resistant alloy bar comprises the steps of smelting, casting moulding, surface carburizing and high frequency quenching. On one hand, the highly wear-resistant alloy bar can be effectively produced, the production and preparation technology is simple, raw materials are convenient to obtain and the cost is relatively low. On the other hand, the structural strength, toughness and wear resistance of the bar can be effectively improved, so that the operation and use performance of the bar are greatly improved, the friction loss dur
