Description

一种硅铁或铬铁铸锭机及其锭模合金
技术领域
本发明涉及铸造领域,尤其涉及一种硅铁或铬铁铸锭机。
背景技术
铁合金生产通常采用以下四种浇铸方式:1.地坑浇铸:将铁水包内的铁水扒干净炉渣后即倒入地坑内,合金冷却后用铲车铲起入库,再加工到合格粒度后销售;2.锭模浇铸:采用底厚为150mm以上的无铁水溢流口的铸铁锭模独立摆放,用行车吊着铁水包移动逐个对锭模进行浇铸,浇铸成厚度200mm以上的产品块,取出后经强力破碎机破碎到小于150mm粒度入库,再加工到合格粒度后销售;3.“地坑—铸铁档块锭模”浇铸:采用铸铁块围成类似锭模的地坑进行浇铸,合金锭厚度在400mm左右,冷却后吊运到加工场地破碎精整,入库后再加工到合格粒度销售;4.砂模浇铸,中低碳锰铁等通常采用这种浇铸方式。其中,锭模浇注可以通过铸铁机实现连续浇铸,例如中国专利201820265401.3公开了一种轨道式铸铁机。
目前,在浇注硅铁锭时使用的浇注模具,仍然采用传统的灰铸铁坯浇注时用的浇注模具,硅铁或者铬铁锭浇注,其浇注温度高达1480~1530℃,比普通灰铸铁铁水浇注温度(1250~1300℃)高约230℃,因此,传统的灰铸铁浇注用的浇注模具并不能满足硅铁锭的浇注要求,因此,硅铁锭连续浇注用的浇注模具已经成为严重制约生产效率的瓶颈。首先,传统的灰铸铁浇注用的浇注模具,在硅铁铁液浇注后,热量传递较慢,铁液内的气泡不能快速充分溢出,铁液与模具易发生熔融粘合,需要在连续浇注机的卸料端专门设置扒料装置,才能使铸坯与模具分离,使用不便,同时,现有模具的导热性、热疲劳性、高温抗氧化性等力学性能已经不能满足硅铁锭连续浇注的需要。
另外,连续浇铸时,刚从铁水包中出来的铁水温度最高,其对锭模寿命影响最大,导致铸铁机上锭模寿命参差不齐,进而影响铸铁机整体使用寿命。
申请人于2018年2月24日申请的发明专利2018101561942公开了一种轨道式铸铁机,申请人在对硅铁或铬铁铸锭时,出现以上问题,申请人对锭模合金材质,以及锭模排布进行了大量研究,已成功解决上述技术问题。
发明内容
本发明要解决的技术问题是:提高铸铁机在浇铸硅铁锭时的使用寿命。
为了实现上述目的,本发明采用了如下技术方案:
一种硅铁或铬铁铸锭机,包括循环轨道、设置在循环轨道上1-n编号的n个锭模,其中,前1-10个锭模为头模;
所述头模为以下元素按重量百分比组成的合金模具:
Mn 3-5%、Si 1-3%、Cr 0.5-1%、Na 0.5-1%、Mg 0.1-0.3%、Ti 0.1-0.3%、P 0.05-0.1%、V0.05-0.1%、S 0.05-0.1%、Gd 0.05-0.1%、Co 0.05-0.1%、Ni 0.05-0.1%、Ho 0.05-0.1%、Eu0.01-0.1%、Cu 0.01-0.03%、Mo 0.005-0.01%、Ir 0.001-0.005%、Pb 0.001-0.005%、余量为Fe;
其他锭模为以下元素按重量百分比组成的合金模具:
Mn 3-5%、Si 1-3%、Cr 0.5-1%、Na 0.5-1%、Mg 0.1-0.3%、Ti 0.1-0.3%、P 0.05-0.1%、V0.05-0.1%、S 0.05-0.1%、Co 0.05-0.1%、Ni 0.05-0.1%、Ho 0.05-0.1%、Eu 0.01-0.1%、Cu0.01-0.03%、Ir 0.001-0.005%、余量为Fe。
进一步,n个锭模容积之和等于同一包铁水的体积。
进一步,锭模的模壁厚度为220-240mm,模铁比为8-9。
进一步,编号设置在锭模外侧。
进一步,头模外侧涂刷有醒目颜色。
一种硅铁或铬铁铸锭机用锭模合金,由以下元素物质铸造而成:
Mn 3-5%、Si 1-3%、Cr 0.5-1%、Na 0.5-1%、Mg 0.1-0.3%、Ti 0.1-0.3%、P 0.05-0.1%、V0.05-0.1%、S 0.05-0.1%、Co 0.05-0.1%、Ni 0.05-0.1%、Ho 0.05-0.1%、Eu 0.01-0.1%、Cu0.01-0.03%、Ir 0.001-0.005%、余量为Fe。
进一步,还包括Gd 0.05-0.1%、Mo 0.005-0.01%、Pb 0.001-0.005%。
与现有技术相比,本发明的有益效果是:
1、本发明通过对锭模厚度、模铁比及合金材料的改进,提高了锭模的耐热稳定性,延长了锭模的使用寿命;
2、本发明通过对铸锭机锭模总容量设计,使得一包铁水在一套铸铁机上完全使用完毕,降低了操作难度;
3、本发明通过对铸锭机头模的性能进一步加强,每次浇铸时都从头模开始,实现了铸铁机锭模的等寿命设计。
具体实施方式
下面结合实施例对本发明做进一步说明。
将发明专利2018101561942公开了一种轨道式铸铁机上的锭模进行编号,编号可以雕刻或印刷在锭模侧壁外侧,1号锭模侧壁外侧用耐火颜料进行涂刷使之醒目,每次浇铸时,均从1号锭模开始,锭模容量根据铁水包容量设计,每个循环为一包铁水,使得每包铁水在同一铸锭机上浇铸完毕,浇铸前,先对锭模内进行刷涂层,涂层采用现有技术中涂层即可。
合金材料制备,按设计重量称取各种元素和无碳铁混合,然后加入熔炼炉中进行熔化使其充分混合,然后向锭模模具中浇铸,经过冷却后得到锭模,该合金无需进行其他热处理。
