Calcium oxide crucible for vacuum melting of high-temperature alloy and preparation method of calcium oxide crucible
The invention discloses a calcium oxide crucible for high-temperature alloy vacuum melting and a preparation method thereof, and the calcium oxide crucible comprises the following raw materials in parts by weight: 90-100 parts of modified calcium oxide, 1.5-2.5 parts of aluminum oxide, 0.5-3 parts of a modified adhesive, 0.1-0.5 part of a defoaming agent and 10-20 parts of absolute ethyl alcohol. The calcium oxide crucible provided by the invention has excellent hydration resistance and thermal shock resistance, so that the service life of the crucible is prolonged, pollution caused by erosion or high-temperature decomposition of a high-temperature alloy by a crucible material can be effectively avoided, and the performance of the high-temperature alloy is improved.
本发明公开了一种用于高温合金真空熔炼的氧化钙坩埚及其制备方法，按重量份计，该氧化钙坩埚包含以下原料：90‑100份改性氧化钙、1.5‑2.5份氧化铝、0.5‑3份改性黏合剂、0.1‑0.5份消泡剂和10‑20份无水乙醇。本发明提供的氧化钙坩埚拥有优异的抗水化性和抗热震性，使得坩埚使用寿命延长，还能够有效避免高温合金受坩埚材料侵蚀或高温分解而造成的污染，提高高温合金的性能。
