Abstract

本发明涉及一种无模可控金属熔铸成型方法。传统的金属铸造工艺无一例外地采用模具铸造,造型不够灵活多变。本发明方法首先将金属在坩埚内熔化,然后金属熔液倒入介质中,金属熔液在介质中自然流淌,根据成品需要控制金属熔液的冷凝速度,再将凝结的金属进行着色和焊接处理。本发明方法的原料来源于金属材料加工剩余的边角余料,节约了成本;利用本发明方法铸造的金属装饰品,造型奇特、色彩丰富,实现了抽象与现实相结合的艺术效果。

Description

一种无模可控金属熔铸成型方法
技术领域
本发明属于金属铸造技术领域,涉及一种无模可控金属熔铸成型的方法。
背景技术
金属制成的装饰品在装饰行业中占有重要地位。一直以来金属装饰品主要是铸造饰品,如佛像、香炉等。而传统的铸造技术一直是金属加工的主流工艺,该技术一般采用泥模、砂模、树脂模、石腊模、金属模等模具。模铸成型是传统的金属雕塑不可缺少的工艺手段,传统的金属雕塑工艺无一例外地采用模具铸造,造型不够灵活多变。
发明内容
本发明的目的是提供一种无模可控金属熔铸成型方法。
本发明方法首先将金属材料在坩埚内熔化,然后将熔化的金属熔液倒入介质中,金属熔液在介质中自然流淌,根据成品需要控制冷凝速度,再将凝结的金属进行着色和焊接处理。其中的介质为气态或液态的物质,温度为0~100℃,介质中也可以加入助凝剂。介质可以是静止状态,也可以是流动状态。将金属熔液倒入介质中时,坩埚可以是处于水平静止状态,也可以通过步进电机控制,使其处于水平运动状态。本发明中的助凝剂为干冰、液氮等。
本发明方法中的熔化、着色、焊接处理的方法采用成熟的现有方法,本发明的发明点在于通过将金属熔液自然倒出、在介质中固化,通过该方法使成品更具自然性。
本发明方法的原料来源于金属材料加工剩余的边角余料,节约了成本。利用本发明方法可以铸造新型的金属装饰品,扩大工艺美术品新领域。本发明方法通过焊接和化学处理,出现奇特的形象,做到了抽象与现实相结合的艺术效果。
具体实施方式
以金属铜为例对本发明的无模可控金属熔铸成型方法做进一步说明。
首先将铜块在坩埚内熔化,然后将熔化的铜液倒入介质水中,铜液在介质水中自然流淌,介质水中局部加入助凝剂,根据成品需要控制冷凝速度,可以得到堆积状、片状、条状、块状等形态的铜件,再将铜件进行着色和焊接处理。
铜进行着色处理时,根据成品的需要控制着色温度和着色时间,其中温度与熔铜色彩的关系如表1:
  温度(℃)   15   25   35   45
  色彩   浅黄色   棕色   深棕色   黑色
表1
随着温度的升高,颜色由浅至深。这是由于在不同温度下,氧化程度不同,因而得到不同的色彩。着色时间与熔铜色彩的关系如表2:
  着色时间   30″   1′   1′30″   3′   5′
  色彩   浅黄   棕黄   棕色   深棕   黑色
表2
常温下,对于一定浓度的着色液,随着时间的增加,颜色逐渐加深,即着色膜的厚度在增加。当达到一定时间后,颜色不再变化而成为黑色。
选用硫化物作为着色液,其浓度与熔铜色彩的关系如表3:
  CuSO4(g/L)   80   90   100   110   120
  色彩   浅棕   棕色   深棕色   棕黑色   黑色
表3
上述色彩变化规律是由于Cu2+是着色液的主要成分。它的含量多少,能改变膜的厚度,从而使着色膜的色彩不同。
该方法采用无模熔铸,造型奇特、色彩丰富,可以制成砂粒、块状、蜂窝等不同形态的熔铜。
