Description

一种雾化成型导流管的制作方法
技术领域
本发明涉及合金钢连铸领域,特别是一种雾化成型导流管及其制造方法。
背景技术
现有技术中雾化器在使用过程中经常遇到喷嘴和导流管堵塞的现象出现,这主要由以下几个方面的原因造成的:一是金属液在流动过程中因为温度降低出现凝固;二是喷嘴射出的气流或多或少地会喷射到导流管端口产生强烈地冷却,使液流凝固堵死导流管和喷嘴;三是导流管下方的负压紊流区,使金属液滴溅到喷嘴口造成堵死;四是由于金属液滴在雾化过程中出现反溅,即雾化的液滴向气流雾化喷嘴的方向飞行,反溅的金属液滴粘附到气流雾化喷嘴的下端,并且不断凝固积累,最终导致气流雾化喷嘴和导流管堵塞而使雾化过程中断;五是气体雾化法制备合金粉末时经常处于氧化气氛中,势必使合金粉末表面发生氧化;即使处于保护气氛下,但由于保护气体并非完全纯净,因此也不可避免使合金粉末表面发生一定程度氧化,在粉末表面形成薄层氧化膜,一旦氧化膜形成一定的厚度层,液滴表面张力完全失效,影响粉末的成球率。另外,金属熔体与雾化器周围气体中的氮气也有可能反应生成金属氮化物。随着这些金属氧化物或氮化物量的增多,会将导流管和喷嘴堵塞。现有技术中的导流管大多采用锆英砂原料制成,在抗冲刷和耐磨性方面性能较差,一般的雾化器导流管形状采用环孔状,是造成堵塞的原因之一。
发明内容
为克服现有技术的不足,本发明的目的在于提供一种雾化成型导流管的制作方法,旨在采用液压干压成型的方法生产出一种以氧化锆为原料的漏斗型导流管,节省原料的同时提高生产效率。
为实现上述目的,本发明通过以下技术方案实现:
一种雾化成型导流管的制作方法,包括以下步骤:
步骤1)把单斜氧化锆和氧化铈加入至球磨机内充分混合均匀,过筛,然后加入结合剂,再加入至混合机内混合均匀;
步骤2)把步骤1)中混合好的粉末通过液压机压成块状,放入烘箱内烘干,然后放入高温窑炉烧至800℃-1000℃并保持该温度1.5小时-3小时,然后关闭窑炉,待其自然冷却至常温后出炉;
步骤3)出炉后的产品经过破碎除铁筛选得到粒径100nm-200nm的混合粉末,加入结合剂混合,放置6小时-8小时后经上压机干压成型,烘干水分,放入电窑中烧至1600℃-1700℃,保温5小时-8小时自然冷却出炉,得到导流管。
优选的是,所述的雾化成型导流管的制作方法,其中,所述导流管呈漏斗型。
优选的是,所述的雾化成型导流管的制作方法,其中,步骤1)和步骤3)所述的结合剂为陶瓷结合剂。
本发明的有益效果是:采用氧化锆和氧化铈为原料生产出的导流管具有耐磨,用时长的特性,无需用等静压机成型加工,直接采用液压干压成型,提高了生产效率,且不浪费原材料,生产的周期短,节约了成本;该导流管的形状为漏斗状,导流管中的金属液滴顺畅的留下,避免了雾化器的导流管堵塞。
