Description

一种不锈钢本色表面管件及其酸洗工艺
技术领域
本发明属于国际专利分类中金属板、管或基本无切削加工领域，特别涉及一种不锈钢本色表面管件及其酸洗工艺。
背景技术
不锈钢管件广泛应用于、石油、化工、医药、食品等领域，产品表面通常为抛丸处理后获得的银亮色表面以及喷砂工艺获得的磨砂表面，不能满足高端装备对不锈钢管件产品提出的不锈钢本色表面的新要求。
发明内容
本发明解决了高端管道工程对不锈钢管件产品提出的不锈钢本色表面的技术难题，为获得钢管打磨、成形、固溶后的颜色和纹理组织与钢管本色相一致的表面，本发明提供了一种不锈钢本色表面管件及其酸洗工艺，包括如下步骤：
1)一次配酸，浓度65%的硝酸占比30%、浓度30%的氢氟酸占比5%、余量为水；
2)一次浸泡，将不锈钢管件淹没配置的酸液中浸泡（30～60）分钟；
3)一次清洗，用（65～85）℃热水冲洗不锈钢管件至光亮洁净，自然晾干30分钟以上；
4)二次配酸，浓度65%的硝酸占比50%、浓度40%硫酸占比10%、浓度30%氢氟酸占比5%、余量为水；
5)二次浸泡，将晾干后的不锈钢管件淹没二次配置的酸液中浸泡（5～10）分钟；
6)二次清洗，用（65～85）℃热水冲洗至管件表面洁净，自然晾干后标识、包装；
第一次浸泡去除不锈钢管件固溶表面氧化黑皮，获得银亮的金属表面。第二次浸泡对表面进行钝化处理，形成的钝化膜颜色基本与不锈钢管表面原色一致。
具体实施方式
一种不锈钢本色表面管件及其酸洗工艺，包括如下步骤：
1)一次配酸，浓度65%的硝酸占比30%、浓度30%的氢氟酸占比5%、余量为水；
2)一次浸泡，将不锈钢管件淹没配置的酸液中浸泡（30～60）分钟；
3)一次清洗，用（65～85）℃热水冲洗不锈钢管件至光亮洁净，自然晾干30分钟以上；
4)二次配酸，浓度65%的硝酸占比50%、浓度40%硫酸占比10%、浓度30%氢氟酸占比5%、余量为水；
5)二次浸泡，将晾干后的不锈钢管件淹没二次配置的酸液中浸泡（5～10）分钟；
6)二次清洗，用（65～85）℃热水冲洗至管件表面洁净，自然晾干后标识、包装；
第一次浸泡去除不锈钢管件固溶表面氧化黑皮，获得银亮的金属表面。第二次浸泡对表面进行钝化处理，形成的钝化膜颜色基本与不锈钢管表面原色一致。
本工艺实施的前提是不锈钢管件固溶处理前消除表面麻点、凹坑、裂纹、划痕等缺陷，固溶后直接转入酸洗工序，中间不允许用机械方式进行表面修补与打磨。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书内容所作的等效流程变换及改进润饰，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
