Antioxidant graphite cast pipe and preparation method thereof
The invention relates to an antioxidant graphite cast pipe and a preparation method thereof, and belongs to the technical field of materials. The antioxidant graphite cast pipe is prepared from the following chemical components, by mass, 0.5-0.7% of silicon dioxide, 0.01-0.08% of phosphorus pentoxide, 0.7-0.9% of aluminum oxide, 0.2-0.4% of zirconium oxide, 0.1-0.3% of diboron trioxide, 0.1-0.3% of magnesium oxide, and the balance of graphite. According to the antioxidant graphite cast pipe, on one hand, the oxidation resistance of the cast pipe can be effectively improved, and the service life of the cast pipe is prolonged; and on the other hand, contact between the graphite cast pipe and a copper solution flowing in the graphite cast pipe can be reduced through an antioxidant protectionlayer, so that carbon dissolution of the copper solution is effectively reduced, carbon inclusion is reduced, the components, the structure and the cold and hot machining performance of cast ingost are improved, and the good popularization value is achieved.
本发明涉及一种抗氧化石墨浇注管及其制备方法，应用于材料技术领域，由以下各组分组成，其化学成分质量百分比为：二氧化硅0.5‑0.7％、五氧化二磷0.01‑0.08％、三氧化二铝0.7‑0.9％、氧化锆0.2‑0.4％、三氧化二硼0.1‑0.3％和氧化镁0.1‑0.3％，余量为石墨。本发明的抗氧化石墨浇注管一方面可以有效提高浇注管的抗氧化性，延长其使用寿命；另一方面，可以通过该抗氧化剂保护层减少石墨浇注管与其内部流动的铜溶液的接触，从而有效减少铜溶液溶碳，降低碳夹杂，改善铸锭的成分、组织和冷热加工性能，有很好的的推广价值。
