Abstract

本发明涉及轴瓦材料生产的一种工艺，是常压状态下，在低碳钢的两面烧结一层铜合金的粉末冶金制造工艺。本发明所采取的技术方案是：在常压条件下，利用粉末冶金烧结工艺，在低碳钢两面铺上合金粉末进行烧结。本发明的有益之处在于：由于用双面烧结代替浇铸工艺，使双面合金产品的产成品率从原来的 50% 提高到 93% ，提高了合金的致密性，减少合金层厚度，降低能源消耗，节约有色金属。

Description

常压条件下低碳钢双面铜合金烧结工艺
技术领域
本发明涉及轴瓦材料生产的一种工艺，是常压状态下，在低碳钢的两面烧结一层铜合金的粉末冶金制造工艺。
技术背景
常压条件下低碳钢双面烧结铜合金的产品由双层的铜基合金耐磨层和低碳钢基层组成，具有很高的抗疲劳强度和大的承载能力，广泛应用于各种轴向推力轴承环（止推环），是机器上的零配件，应用配套于：柴油机、汽车、农用机械、液压机械、机床、林业机械、工程机械、铁路、船舶、石油化工机械、冶金设备等。传统的铜基-钢双面合金材料为浇铸工艺，该工艺生产的产品成品率较低，而且合金厚度厚，造成材料浪费的现象。常压条件下低碳钢双面烧结工艺，是经过不断技术改进而研发出的一种较为先进的生产工艺，它不仅有效解决了传统工艺存在的缺点，而且产成品的性能也得到提升，成为轴瓦材料生产的趋势。
发明内容
本发明工艺的目的在于提供一种双面烧结工艺，替代了传统的浇铸工艺，生产的产品具有大的承载能力和强的双面抗冲击力等特性。
本发明所采取的技术方案是：在常压条件下，利用粉末冶金烧结工艺，在低碳钢两面铺上合金粉末进行烧结。
本发明的有益之处在于：由于用双面烧结代替浇铸工艺，使双面合金产品的产成品率从原来的50%提高到93%，提高了合金的致密性，减少合金层厚度，降低能源消耗，节约有色金属。
附图说明
图1为工艺流程图。
具体实施方式
如图1所示为本发明工艺流程图。顺序依次为:下料、轧制、校平、清洗、第一次铺粉、烧结、第二次铺粉、烧结、轧制、复烧、轧制。每道工序都要经过严格的质量检验才能转到下一道工序。
