Calcining method of alumina milling balls
The invention discloses a calcining method of alumina milling balls. The calcining method comprises the following steps of: calcining; (1) preparation of alumina blank balls; (2) preparation of the alumina milling balls: placing the aluminum oxide blank ball into a crucible, putting the crucible into a sintering furnace, removing moisture at 150-200 DEG C, discharging glue at 400-800 DEG C, calcining the blank balls at 1200-1650 DEG C at a heating rate of 2-5 DEG C/min to obtain the alumina milling balls, which are densified by adopting different calcining temperatures, so that the loss of themilling balls is reduced; the mass density of the alumina balls is improved by adopting different heat-preservation time.
本发明公开了一种氧化铝研磨球的煅烧方法，所述煅烧方法包括如下步骤：1)氧化铝素胚球制备：2)氧化铝研磨球制备：将氧化铝素胚球装入坩埚并放入烧结炉中，150‑200℃排除水分，400‑800℃进行排胶，煅烧烧结温度1200‑1650℃进行煅烧，升温速率2‑5℃/min，得到氧化铝研磨球。本发明采用不同煅烧温度对氧化铝球进行致密化，从而降低研磨球损耗；采用不同保温时间提高氧化铝球质量密度。
