Embodiment 1
[0016] The present invention proposes a high-toughness, high-hardness anti-fatigue liner for a ball mill, and its components include: carbon 2.65%, chromium 7.2%, silicon 0.85%, manganese 0.7%, copper 0.9%, molybdenum 0.52%, titanium 0.45%, vanadium 0.2%, yttrium-based heavy rare earth 0.2%, sulfur ≤ 0.04%, phosphorus ≤ 0.04%, the rest is iron and other small amounts of unavoidable impurities;
[0017] During the preparation process, the following steps are used to prepare the high toughness and high hardness anti-fatigue liner for the ball mill:
[0018] S1. First, melt high-carbon ferrochrome in an intermediate frequency induction furnace, continue to heat up to 1470°C, and then add scrap steel, ferromanganese, ferroniobium, ferromolybdenum, ferrovanadium, and rare earth alloys to form a melt; then add ferrotitanium and vanadium Iron, when the temperature rises to 1530°C, remove scum, then add ferroboron, stir evenly, add yttrium-based heavy metal, stir evenly, remove slag, ...
