Description

一种铁硅铬锗钛合金软磁粉末水气联合雾化制备方法
技术领域
本发明涉及软磁合金粉末技术领域,更具体地说是指一种铁硅铬锗钛合金软磁粉末水气联合雾化制备方法。
背景技术
目前,金属软磁粉末通常是以铁硅铬为主,采用化学反应法、熔体雾化法、机械破碎法和点解沉积法等制备方法制成,其中,熔体雾化法制备合金粉末拥有与既定熔融合金完全相同的化学成分,还具有典型的快速凝固组织,合金成分范围宽,粉末形貌球形度好,粒度分布宽的特点,被广泛的应用当下金属软磁粉末制作。
但是,随着科技的发展,电子元器件的应用越来越广,且随着产品性能的提高,对电子元器件所用的磁性材料要求越来越高,特别是针对不同电子产品其功能不同,对金属软磁粉末的材料性质要求也不同,如部分电感器件对软磁材料需要较高的磁导率、饱和特性和耐损耗,而通过上述熔体雾化法制取的铁硅铬软磁粉末,其存在粉末振实密度低、磁导率低、耐损耗低和易饱和等缺陷,无法满足客户实际需求。
发明内容
本发明提供一种铁硅铬锗钛合金软磁粉末水气联合雾化制备方法,以解决现有金属软磁粉末存在的振实密度低、磁导率低和耐损耗低等缺陷。
本发明采用如下技术方案:
一种铁硅铬锗钛合金软磁粉末水气联合雾化制备方法,包括如下步骤:
1)将含有铁、硅、铬、锗、钛的软磁合金粉末原料加入中频感应炉内,采用吹氩保护冶炼得到合金液。
2)在氮气保护条件下,将合金液浇注入负压环境的雾化塔内,浇注过程中,通过负压超速气体和高压雾化水两种介质先后作用于合金液柱流,合金液柱流先在负压超音速气体作用下,被分散撕裂成金属液滴,然后再通过高压雾化水的冲击和冷却,将金属液滴进一步破碎冷却呈近球形的合金软磁粉末。
上述,最终制成的合金软磁粉末质量比为:铬0.1-10%,硅2-8%,锗0.1-8%,钛0.1-8%,铁余量。
进一步地,所述1)冶炼过程中,在预制坩埚中,底部预埋气砖,中频感应炉炉口用炉盖封闭,用氩气作为炉口保护气体。冶炼合金液时,先将铁、铬、硅按顺序先后加入中频感应炉完全熔化,在温度达到1580-1600度时,开始炉底吹氩;在温度达到1640-1660度时,开启炉口吹氩,随后加入锗、钛;镇静除渣后,得到合金液。
进一步地,所述步骤2)雾化塔的雾化桶加装变频低压引风机、压力传感器、单向阀、定向管道、冷凝器和导流板,通过压力传感器和变频低压引风机将雾化桶内压力维持在98-99KPa压力条件下,将合金液浇注入负压环境的雾化塔内,雾化桶内用氮气作为保护气氛,氮气流量在10-20M3/H,氮气通过变频低压引风机、定向管道、冷凝器和导流板在雾化桶内高速定向流动,形成负压超音速气体,将合金液柱流分散撕裂成金属液滴。
进一步地,浇注过程中漏包采用氩气保护,漏眼直径5-8毫米。
进一步地,所述负压超音速气体的压力为0.1-10KPa,速度为1—5马赫。
进一步地,所述高压雾化水的喷射压力120-200MPa,流量为150-350L/min。
由上述对本发明结构的描述可知,和现有技术相比,本发明具有如下优点:
本发明制得的合金软磁粉末相较于传统的铁硅铬软磁粉末,由于锗、钛元素的加入可以起到对合金软磁粉末细化晶粒,改善组织缺陷的效果,并明显改善了粉末在软磁电感器件应用中的磁导率特性、饱和特性和磁损。此外,本发明不同传统雾化法的气体吹散合金液柱流,而是采用负压环境下通过负压超音速气体作用将合金液柱流分散撕裂成金属液滴,避免了传统正压气体将水分子、保护气体分子、空气中的杂质吹击在金属液滴表面,影响在金属液滴表面元素分布。
具体实施方式
下面说明本发明实施例的具体实施方式。
一种铁硅铬锗钛合金软磁粉末水气联合雾化制备方法,包括如下步骤:
1) 将含有铁、硅、铬、锗、钛的软磁合金粉末原料加入中频感应炉内,采用吹氩保护冶炼得到合金液。
进一步,在冶炼过程中,在预制坩埚中,底部预埋气砖,中频感应炉的炉口用炉盖封闭,用氩气作为炉口保护气体。冶炼时,先将铁、铬、硅按顺序先后加入中频感应炉完全熔化,在温度达到1580-1600度时,开始炉底吹氩;在温度达到1640-1660度时,开启炉口吹氩,随后加入锗、钛;镇静除渣后,得到合金液。
上述冶炼中,锗、钛两种元素因容易氧化,在熔炼过程中,要往相对靠后的顺序加入,并且在加入的过程中通过氩气和炉盖保护,以降低冶炼过程中锗、钛的氧化,降低合金液中的氧化物杂质。
2)在氮气保护条件下,将合金液浇注入负压环境的雾化塔内,浇注过程中,通过负压超速气体和高压雾化水两种介质先后作用于合金液柱流,合金液柱流先在负压超音速气体作用下,被分散撕裂成金属液滴,然后再通过高压雾化水的冲击和冷却,将金属液滴进一步破碎冷却呈近球形的合金软磁粉末。制成的软磁合金粉末原料质量比为:铬0.1-10%,硅2-8%,锗0.1-8%,钛0.1-8%,铁余量。
更具体的,雾化塔的雾化桶加装变频低压引风机、压力传感器、单向阀、定向管道、冷凝器和导流板,通过压力传感器和变频低压引风机将雾化桶内压力维持在98-99KPa压力条件下。将合金液浇注入负压环境的雾化塔内,雾化桶内用氮气作为保护气氛,氮气流量控制在在10-20M3/H。浇注过程中漏包采用氩气保护,漏眼直径4-6毫米,氮气作为破碎气体,通过变频低压引风机、定向管道、冷凝器和导流板在雾化桶内高速定向流动,没有涡旋,降低了涡旋产生的能量损耗,形成负压超音速气体,作为优选负压超音速气体的压力控制在0.1-10KPa,速度控制在1—5马赫。合金液柱流在负压超音速气体作用下,通过改变气体速度和压力,利用气体压力从高到低、再从低到高,气体体积压缩膨胀的快速变化,将合金液柱流分散撕裂成金属液滴。然后再通过高压雾化水的冲击和冷却,将金属液滴进一步破碎冷却成近球形的合金软磁粉末,由此,得到本发明金属软磁粉末颗粒。作为优选,高压雾化水的喷射压力控制在120-200MPa;流量控制在150-350L/min,氨水溶液浓度为0.5-2%。
本发明制得的合金软磁粉末相较于传统的铁硅铬软磁粉末,由于锗、钛元素的加入可以起到对合金软磁粉末细化晶粒,改善组织缺陷的效果,并明显改善了粉末在软磁电感器件应用中的磁导率特性、饱和特性和磁损。此外,本发明不同传统雾化法的气体吹散合金液柱流,而是采用负压环境下通过负压超音速气体作用将合金液柱流分散撕裂成金属液滴,避免了传统正压气体将水分子、保护气体分子、空气中的杂质吹击在金属液滴表面,影响在金属液滴表面元素分布。
经检测,下面为本发明所制制成的产品B与现有雾化法制成的铁硅铬产品A的材料性能对比表。
