高频振动浇注高细化合金耐磨球及其制备方法
摘要：
本发明公开了一种高频振动浇注高细化合金耐磨球及其制备方法，其各化学成分按重量百分比为：C 1.8～2.5％、Cr 1.5～2.5％、Mn 0.8～1.2％、Si0.4～0.6％、Ti 0.2～0.3％、Ni 0.2～0.3％、B 0.025～0.03％、Re 0.02～0.03％、S≤0.06％、P≤0.06％，其余为Fe和不可避免的杂质；晶相组织为碳化物+珠光体。本发明制得的高频振动浇注高细化合金耐磨球，能够在低铬含量的基础上达到高铬磨球的硬度和耐磨性，有效的降低材料的使用成本。
摘要（英）：

The invention discloses a high-frequency vibration casting high-refinement alloy abrasion-resistant ball and a preparation method thereof. The high-frequency vibration casting high-refinement alloy abrasion-resistant ball comprises the following chemical components by weight percentage: 1.8-2.5% of C, 1.5-2.5% of Cr, 0.8-1.2% of Mn, 0.4-0.6% of Si, 0.2-0.3% of Ti, 0.2-0.3% of Ni, 0.025-0.03% of B,0.02-0.03% of Re, less than or equal to 0.06% of S, less than or equal to 0.06% of P, and the balance of Fe and inevitable impurity; and a crystalline phase tissue is carbide and pearlite. The high-frequency vibration casting high-refinement alloy abrasion-resistant ball can reach hardness and wear resistance of high-chromium grinding balls based on low-chromium content, and effectively reduces the usage cost of the materials.
