Preparation method of high-strength and high-density graphite casting mold material
The invention provides a rapid low-cost preparation method of a high-strength high-density graphite casting mold material, which mainly comprises the following steps: graphite powder pretreatment, mixed powder preparation, unit layer micro hot press molding, interlayer exhaust network construction, multiple repetition, hot press curing, cooling demolding, rapid carbonization, multiple dipping reinforcement and graphitization. And finally obtaining the graphite casting mold material. Compared with the traditional graphite casting material preparation process, the preparation method has the advantages of short production flow and low energy consumption, effectively reduces the cost by taking the waste artificial graphite powder as the main raw material, and meets the requirements of rapidness, high efficiency and low cost. The prepared graphite casting mold material has the properties of high strength, high density and the like, is expected to replace a traditional artificial graphite casting mold and is applied to the casting industry.
本发明提出了一种高强高密石墨铸型材料的快速低成本制备方法，主要包括如下步骤：石墨粉末预处理、混合粉末制备、单元层微热压成型、层间排气网络构造、多次重复、热压固化、冷却脱模、快速碳化、多次浸渍强化、石墨化，最终获得石墨铸型材料。本发明与传统的石墨铸型材料制备工艺过程相比，生产流程短、能耗低、且以废弃的人造石墨粉末为主要原材料有效地降低了成本，满足快速高效、低成本的要求。所制备的石墨铸型材料具有高强高密等性能，有望替代传统的人造石墨铸型，应用于铸造行业。
