Preparation method of smelting crucible for smelting iron-based alloy
The invention relates to a preparation method of a smelting crucible for smelting an iron-based alloy. The preparation method comprises the following steps: S1, mounting a coil; s2, crucible knotting is conducted, specifically, a coil supporting bottom plate is embedded into the bottom of the coil, and a protective layer is arranged on the inner wall of the coil; a furnace lining dry vibration material is added for ramming, an iron mold is placed after ramming is conducted to a preset height, the iron mold is coaxial with a coil of the medium-frequency smelting furnace, the furnace lining dry vibration material continues to be added, the side wall of the crucible is knotted, and the junction corner of the side wall of the crucible and the bottom of the crucible is of a chamfer structure; s3, baking and sintering the crucible: heating the furnace charge to 1000-1100 DEG C at a uniform heating rate; after heat preservation is finished, the temperature continues to be increased to 1620-1660 DEG C at the uniform speed for iron material melting, heat preservation is conducted, and the inner surface layer of the crucible is sintered; and after heat preservation is finished, impurities in the molten metal are removed, and the furnace is closed for vacuumizing. According to the preparation method of the smelting crucible provided by the invention, the formation of a high-strength sintering layer can be ensured, the density of the crucible is improved, the mixing of a dry vibration material can be reduced, and the purity of an alloy solution is improved.
本发明涉及一种用于熔炼铁基合金的熔炼坩埚的制备方法，包括以下步骤：S1，安装线圈；S2，坩埚打结：将线圈支撑底板嵌入线圈底部，在线圈内壁置入防护层；加入炉衬干振料进行捣打，捣打至预定高度后放入铁模，所述铁模与中频熔炼炉的线圈同轴，继续加入炉衬干振料，打结坩埚侧壁，所述坩埚侧壁和坩埚底的交界转角处为倒角结构；S3，坩埚烘烤烧结：以均速的升温速率将炉料加热到1000‑1100℃；保温结束后继续均速升温至1620‑1660℃进行铁料熔化，并保温，对坩埚内表层进行烧结；保温结束后去除金属液内的杂质，并合炉抽真空。本发明提供的熔炼坩埚的制备方法，能够确保高强度烧结层的形成，提升坩埚致密度，还能够降低干振料的混入，提升合金溶液的纯净度。
