Preparation method of crucible for vacuum induction melting furnace
The invention discloses a preparation method of a crucible for a vacuum induction melting furnace. The method sequentially comprises the following steps of: knotting a crucible bottom at the bottom in an induction coil in a vacuum induction melting furnace by adopting a refractory material; placing an iron mold core manufactured with the size of the inner cavity of the crucible as the boundary dimension in the middle of the crucible bottom, adding a refractory material into a cavity between the iron mold core and the induction coil, and tamping to form a crucible wall; and electrifying the induction coil to inductively heat the iron mold core and the furnace burden distributed in the iron mold core, and tapping till the iron mold core and the furnace burden are completely molten to obtain the sintered crucible, wherein industrial pure iron is selected as the furnace burden. According to the invention, the iron mold core and the furnace burden can be heated and melted, and steel can be directly discharged in a liquid state after sintering is completed, so that the difficulty in taking out the mold core after the crucible is sintered is reduced, and the problem that the crucible is cracked and even scrapped due to pulling force when the mold core is taken down is solved.
本发明揭示了一种真空感应熔炼炉用坩埚的制备方法。所述方法包括依序进行的：在真空感应熔炼炉中感应圈内的底部，采用耐火材料打结出坩埚底；将以坩埚内腔尺寸作为外形尺寸制作的铁模芯在所述坩埚底上居中放置，而后向铁模芯和感应圈之间的空腔中加耐火材料并夯实，以形成坩埚壁；将所述感应圈通电，以感应加热所述铁模芯及布在所述铁模芯内的炉料，所述炉料选用工业纯铁，至所述铁模芯及所述炉料全部熔化后出钢，得到烧结后的坩埚。铁模芯和炉料可以受热熔化，在烧结完成后可以直接通过液态方式出钢，降低了坩埚烧结后的模芯的取出难度，避免了由模芯取下时的拉拽力所导致的坩埚裂纹甚至报废的问题。
