Description

不锈钢超微丝生产工艺
技术领域
本发明涉及一种能够拉出φ0.018mm不锈钢微丝的彩色不锈钢超微丝生产工艺,属不锈钢拉丝工艺领域。 
背景技术
目前,不锈钢拉丝工艺由于套模配比不当所造成的套模磨损情况十分严重,比如一次拉100g的不锈钢微丝,每拉一次几乎要修一次,修二次不超差,能拉三次,对于300g的拉丝,一只模子180元,1kg不锈钢丝的模具费就是600元。如果修第二次就超差,只能拉二次,200g,1kg不锈钢丝的模具费就是900元。按现在的销售价,既使最优质的不锈钢丝,其销价是1300元/kg,次品是1000元/kg,所以模具费是900元就要赔本,几乎没有工厂愿意接这种活,原因就是成本太高,投入产出不成比例,没有利润可言。 
发明内容
设计目的:避免背景技术中的不足之处,在现有不锈钢拉丝工艺的基础上,通过对原料选择及套模的科学匹配,从而达到降低不锈钢拉丝成本的彩色不锈钢超微丝生产工艺。 
设计方案:为了实现上述目的。1、选用φ0.2mm不锈钢丝作为原料且通过不锈钢拉丝机拉到φ0.035mm,作为拉φ0.018mm~0.015mm的坯丝的选择,是本发明的技术特征之一。这样做的目的在于:一是本申请在经过 大量的科学试验的基础,发现选择φ0.2mm进口或国产原料作为不锈钢拉丝的坯料,无论是全自动不锈钢拉丝机,还是在半自动拉丝机上,都可以不间断地拉到φ0.035mm,而且所拉出的不锈钢丝的直径相同;二是在大量试验的基础上,本申请人发现用φ0.035mm不锈钢丝,作为拉φ0.018mm~0.015mm的坯丝且与内径分别是0.030,0.027,0.025,0.023,0.021,0.020,0.019,0.018拉丝成型模构成的套模或0.030,0.027,0.025,0.023,0.021,0.020,0.019,0.018,0.017,0.016,0.015拉丝成型模构成的套模相匹配,既可以成功地拉出所需的超细不锈钢微丝,而且不会发生断丝现象,更重要的是减小了对套模的磨损,极大地延长了套模的使用寿命,从而有效地降低了不锈钢微丝的制造成本。2、气相氧化法是微丝以每秒几米的高速通过高温的氧化性气氛,在微丝表面生成几十到几百纳米厚的透明薄膜,不同厚度,不同成分的薄膜呈现不同的颜色的设计,是本发明的特征之二。这样做的目的在于:确定工艺参数:第一类设备因素:炉温的波动程度、各炉管之间的温差、走丝速度的范围是设备因素,对选定的设备已不能改变,只能了解它们的作用和对生产有多大限制,成为这台设备的特点供生产中参考;第二类是工艺条件:微丝的直径、成分、原始状态(生丝或熟丝)、花度和表面的洁净度,它们在着色过程中是不能改变的,确定了要着色的丝,直径、成分和原始状态就定了,属于工艺条件。这些条件不同对应不同的工艺。花度和清净洁度对薄膜有影响,对生产影响不大,只需对供着色的丝提出要求即可。第三类是在着色前要调定的工艺参数,温度、气氛和张力。炉子的温度是影响薄膜最灵敏的参数,但在着色过程中不能调,只能根据工艺事先升温到要求的温度,在着色过程中要保持稳定。气氛我们采用二种,空气和氧气。用那种气事先要选定,中途也不可换的。气体的流量可调,由于作用不明显,一般不调。张力决定于放线机构,我们用不同的毛刷改变张力,毛刷中途也不 能换。张力对薄膜的影响较弱,主要按排线要求确定张力,暂时不作为工艺参数。第四类是操作参数。收线速度是唯一能在着色过程中调节的工艺参数,实际上它是改变丝在炉内的保温时间,它也是一个灵敏参数。调它并不能任意调整膜的厚度,只是在给定其他参数后在一定范围内调整膜的厚度。线轴不同,也改变收线的速度,只是每次用的线轴是固定的,改变线轴还会改变其他参数,所以只是一个工艺条件。 
技术方案:彩色不锈钢超微丝生产工艺,它包括不锈钢拉丝机,(1)原料选择:选用φ0.2mm不锈钢丝作为原料且通过不锈钢拉丝机拉到φ0.035mm,作为拉φ0.018mm~0.015mm的坯丝;(2)配模:将多个拉丝模构成的套模与成型模配套,其多个拉丝模的内径分别是0.030,0.027,0.025,0.023,0.021,0.020,0.019;或0.030,0.027,0.025,0.023,0.021,0.020,0.019,0.018,0.017,0.016,成型模的内径是0.018或0.015,坯丝经上述套模和成型模拉丝得到微丝。(3)微丝以每秒小于10米的速度高速通过高温的氧化性气氛,在微丝表面生成几十到几百纳米厚的透明薄膜,不同厚度,不同成分的薄膜呈现不同的颜色。 
本发明与背景技术相比,不锈钢超微丝坯丝的选择及模套的科学匹配,不仅从根本上降低了不锈钢超微丝的生产成本,提高了生产效率,而且可以用于进口或国产材料的超微拉丝且不会产生断丝,不仅确保了不锈钢超微拉丝的成品率,而且极大地延长了套模的使用寿命,大幅度地降低了不锈钢超微丝的制造成本。

具体实施方式:
实施例1:彩色不锈钢超微丝生产工艺,它包括不锈钢微丝工艺及不锈钢拉丝机,所述的不锈钢超微丝拉丝工艺是在不锈钢拉丝工艺的基础上:(1)原料选择:选用φ0.2mm不锈钢丝作为原料且通过不锈钢拉丝机拉到φ0.035mm,作为拉φ0.018mm~0.015mm的坯丝;(2)配模:将多个拉丝模构成的套模与成型模配套,其多个拉丝模的内径分别是0.030,0.027,0.025,0.023,0.021,0.020,0.019;或0.030,0.027,0.025,0.023,0.021,0.020,0.019,0.018,0.017,0.016,成型模的内径是0.018或0.015,坯丝经上述套模和成型模拉丝得到微丝。(3)微丝以每秒小于10米的速度高速通过高温的氧化性气氛,在微丝表面生成几十到几百纳米厚的透明薄膜,不同厚度,不同成分的薄膜呈现不同的颜色。所采用的拉丝机是全自动或半自动不锈钢拉丝机。微丝通过1200~1600mm长的炉管恒温区且炉管内通氧化性气氛,其退火炉的控温精度控制在±1℃,炉管内管为石英管,避免被氧化性气氛腐蚀。 
需要理解到的是:上述实施例虽然对本发明作了比较详细的文字描述,但是这些文字描述,只是对本发明设计思路的简单描述,而不是对本发明设计思路的限制,任何不超出本发明设计思路的组合、增加或修改,均落入本发明的保护范围内。
