Aluminum nitride ball rolling forming method
The invention relates to the field of preparation of aluminum nitride balls, and provides an aluminum nitride ball rolling forming method, which solves the problem that a product obtained by an aluminum nitride rolling forming method in the prior art is easy to layer, and comprises the following preparation steps: (1) preparing raw materials; (2) preparing a gel pre-solution; (3) heating the pre-gel solution to 50-58 DEG C, and keeping the temperature; and (4) mixing the raw materials in the step (1), adding a grinding aid, grinding to obtain 10000-12000-mesh slurry, drying to obtain ceramic powder, feeding the ceramic powder part into a rolling forming machine, forming to obtain seed balls, simultaneously spraying the gel pre-solution in the step (3) and cold water at the temperature of 1-5 DEG C on the surfaces of the seed balls in the rolling forming machine, and uniformly stirring to obtain the seed balls. Continuously adding ceramic powder and rolling into balls to obtain grinding ball blanks; and (5) drying, sintering in a kiln, and polishing to obtain the aluminum nitride ball.
本发明涉及氮化铝球的制备领域，提供一种氮化铝球滚制成型方法，解决现有技术的氮化铝滚制成型方法获得的产品容易分层的问题，包括以下制备步骤：(1)原料的准备；(2)凝胶前液的制备；(3)将凝胶前液加热至50－58℃，并保温；(4)将步骤(1)的原料混合，加入研磨助剂进行研磨，得到10000－12000目的浆料，烘干后得到陶瓷粉料，将所述陶瓷粉料部分先送入滚制成型机中成型，得到种球，再在滚制成型机中的种球表面同时喷洒步骤(3)的凝胶前液和温度为1－5℃的冷水，继续持续加入陶瓷粉料滚制成球，得到研磨球坯；(5)干燥、送入窑炉烧结，再进行抛光处理，即得到氮化铝球。
