| description | The invention discloses a wear-resisting alloy steel with high boron, high chrome and low carbon and a preparation method thereof, which comprises the following chemical constituents in weight percent: 0.1-0.5% of C, 3-26% of Cr, 0.5-1.2% of Si, 0.5-1.5% of Mn, 0.3-2.8% of B, 0.3-2.6% of Cu, 0.2-0.6% of Ti, 0.02-0.15% of Ca, 0.03-0.25% of Ce, 0.02-0.18% of N, 0.05-0.3% of Nb, 0.04-0.09% of Al, 0.02-0.15% of Mg, 0.04-0.13% of K, less than 0.03% of S, less than 0.04% of P and the balance Fe and unavoidable impurity elements. The method comprises the following steps: melting steel scrap and chromium iron in an electric furnace; adding copper plates, ferrosilicon, ferromanganese into the melted steel scrap and chromium iron, heating the melt to 1560-1620 DEG C after the constituents are adjusted to be qualified in stokehold; adding calcium-silicon alloy and aluminium deoxidation into the melt; and then adding ferrotitanium and ferroboron in sequence, melting and discharging; roasting the compound inoculant compos |
