一种耐磨性好的铁氧体磁瓦及其制作工艺及其制备工艺
技术领域
本发明涉及特种砂浆领域,特别涉及一种耐磨性好的铁氧体磁瓦及其制作工艺及其制备工艺。
背景技术
磁瓦主要用在永磁直流电机中,与电磁式电机通过励磁线圈产生磁势源不同,永磁电机是以永磁材料产生恒定磁势源。永磁磁瓦代替电励磁具有很多优点,可使电机结构简单、维修方便、重量轻、体积小、使用可靠、用铜量少、铜耗低、能耗小等,当今社会,随着电子工业的飞速发展,铁氧体磁瓦等磁性材料的需求量越来越多。虽然我国是磁性材料生产大国,但是我们的产品尺寸精度,性能档次相对于发达国家来说还有很大的差距,因此我们要从工装设备,生产工艺技术要求方面大力着手,改革,以提高产品质量。目前现有的永磁铁氧体磁瓦及其制作方法生产过程比较复杂,生产工艺不够成熟,产品精度较差,在现有的技术基础上进行技术创新。
发明内容

优选的,所述硅酸盐纤维中的各类添加剂均等量配置。
优选的,所述铁红与辅料的质量配比为5.6:1。
一种耐磨性好的铁氧体磁瓦的制备工艺,包括以下流程:
S1、材料与设备准备,根据铁氧体磁瓦的大小,事先预估并准备好足够的配方中的材料,同时准备好大小合适的烧结、打磨设备;
S2、用量计算与设备试机,根据作业区铁氧体磁瓦的需求量以及配比计算出各种材料的需求量,同时将预烧设备提前加热;
S3、基材混合,将配方中的铁红加入加温设备,开启加热设备并进行预烧混合,使铁红混合均匀,将预烧料加水搅拌后压制成块型,放入炉内在1250°C-1280°C的温度下烧制,时间控制在4h~6h, 推进速度38~45min/板;
S4、一次球磨,将预烧混合完成后的铁红取出移动至打磨区,通过设置好的球型打磨工具为铁红进行第一次干打磨, 使预烧料均匀混合,预烧料的颗粒≤5μm。
S5、助剂混合,将进行一次球磨后的铁红取出 ,将烧结成型的块料进行粉碎,粉料的颗粒≤3.5μm,将混合料中加入碳酸钙3%,二氧化硅2%,氧化镧1%,硫酸锶4%,三氧化二铝2%。
S6、二次球磨,先将混料在球磨机内进行粗球磨,料浆粒度控制在1.0μm~1.3μm,再将料浆打入细磨球磨机内,并按重量百分比加入硅酸盐纤维0.8%以及分散剂1%、硼酸0.8%、苏打0.4%,料浆粒度控制在0.75μm~0.85μm。
S7、烧结削磨,将得到的生坯在温度为1200°C~1350°C下烧结,烧结时间每板推进速度为8分钟~14分钟/板, 保温时间2-3小时后出炉,将烧结料自然冷却至常温状态,然后将生胚削磨至所需尺寸。
S8、清洗充磁,将削磨完成后的生胚进行清洗充磁。
优选的,所述S4步骤中球磨机内球型打磨装置直径为20mm,所述S6步骤中球磨机内粗球型打磨装置直径为30mm,细磨球打磨装置直径为5mm。
优选的,所述S7步骤中若烧结完成后的的生胚,若削磨后发现生胚松散则添加基材混合物,若削磨后发现生胚削磨时间过长则延长球磨机的打磨时间。
与现有技术相比,本发明一种耐磨性好的铁氧体磁瓦及其制作工艺及其制备工艺,通过铁红加温煅烧后进过第一轮干打磨,从而提高铁氧体磁瓦干燥成型后的耐磨性能,同时通过添加各种辅料以及各种功能添加剂,配合专门的铁氧体磁瓦二次湿磨、烧结削磨制备工艺,使得制成的铁氧体磁瓦具有良好的耐磨性能,从而避免了铁氧体磁瓦在频繁使用过程中发生损坏,造成不必要的经济损失。
