Method for preparing graphite sagger from graphite waste
The invention provides a method for preparing a graphite sagger from graphite waste. The method comprises the following steps of: crushing and grinding the graphite waste, heating and mixing coal pitch, pressing and forming by a mold, and carbonizing and sintering under the protection of atmosphere, wherein the graphite sagger comprises 80-90% of waste graphite powder, 8-15% of coal pitch and 2-5% of graphite carbon powder. According to the invention, a lot of graphite waste produced in industrial production can be fully utilized, the production cost is low, the cutting process is omitted, the process is simple and easy to implement, an atmosphere protection roller kiln is used for rapid carbonization sintering, the sintering time is short, the product quality is stable, the yield is high, the energy consumption is greatly reduced, and the product quality is stable.
本发明提供一种利用石墨废料制备石墨匣钵的方法，包括石墨废料破碎磨粉、煤沥青加热混合、模具压制成型、气氛保护碳化烧结，其中80～90％的废旧石墨粉、8～15％的煤沥青、2～5％的石墨碳粉，本发明充分利用工业生产产生的大量石墨废料作为原料，生产成本低，节省了切削加工工序，工艺简单易实现，利用气氛保护辊道窑快速碳化烧结，烧结时间短且产品质量稳定，产量高，大幅降低能耗，且产品质量稳定。
