Embodiment 1
[0055] A) Preparation of wear-resistant pipe body
[0056] 1) To obtain materials, select raw materials with the following chemical composition weight percentages:
[0057] C: 1.6%, V: 4.5%,
[0058] W: 9.1%, Mo: 7.6%,
[0059] Cr: 3.8%, RE: 0.15%,
[0060] Mn: 0.7%, Si: 0.05%,
[0061] B: 0.02%, Al: 0.2%,
[0062] Nb: 0.08%, Ni: 0.1%,
[0063] The balance is Fe and trace unavoidable impurities;
[0064] 2) Mix and heat ordinary steel scrap, micro-carbon ferrochrome, ferroniobium, ferronickel, ferrotungsten, ferromolybdenum, ferrochrome and ferromanganese, add carbon with pig iron or graphite, mix and heat to melt into molten steel, and add the molten steel after it is melted Ferrosilicon for pre-deoxidation;
[0065] 3) According to the distribution ratio of raw materials, adjust the composition in front of the furnace and raise the temperature to 1580°C, then add aluminum blocks for final deoxidation, and then leave the furnace;
[0066] 4) Put the rare earth ferrosi...
