Durable crucible for preparing metal powder
The invention discloses a durable crucible for preparing metal powder. The durable crucible comprises a crucible body, a liquid separation funnel and a flow guide pipe, wherein the crucible body is used for melting the metal powder; the liquid separation funnel is arranged on the crucible body and is used for guiding metal liquid to a liquid guide pipe; the flow guide pipe is in threaded connection with the bottom of the liquid separation funnel and is used for preparing powder through gas atomization; a protection coating is arranged on the inner wall of the crucible body; and a reinforcing layer and an induction coil layer are arranged on the outer wall of the crucible body. The durable crucible has the following advantages that three reinforcing layers are arranged; a certain expansionspace is given to the crucible body, so that an inner protection layer expands along with the crucible body without influencing the compactness of an outer protection layer; the crack repair is convenient; the reinforcement is realized; the crack occurrence probability is reduced; the metal liquid is prevented from flowing into the induction coil layer through the crack of the crucible body; the reaction of the graphite material crucible and the molten metal alloy liquid is effectively retarded; the crucible body damage due to reaction is reduced; and the circulation service life of the crucible body is prolonged.
本发明公开了一种用于制备金属粉末的耐用坩埚，包括坩埚体、隔液漏斗和导流管，所述坩埚体用于熔融金属粉末，所述隔液漏斗设置于坩埚体，用于将金属液引流至导液管，所述导流管螺纹连接于隔液漏斗底部，用于气雾化制粉，所述坩埚体内壁上设有防护涂层，外壁上设有加固层和感应线圈层。本发明具有如下优点：设置三层加固层，给予坩埚体一定的膨胀空间，让内部保护层随之膨胀而不影响外部保护层的致密，方便修补裂缝，加固并减少出现裂缝的概率，避免金属液体通过坩埚体的裂缝流入感应线圈层，有效减缓石墨材质坩埚同熔融金属合金液的反应，降低反应引起的坩埚体损坏，提高坩埚体的循环使用寿命。
