Description
技术领域
本发明涉及粉末冶金领域,特别涉及一种粉末冶金用含铜铁粉及其制备方法。
背景技术
水雾化铁粉常用作制备粉末冶金制品零件用基础原材料,但在使用过程中常常需要添加石墨、铜粉(电解铜粉、雾化铜粉等)等合金辅料用以提高最终制品零件产品的各种性能,以达到其最佳的使用效果。
目前,铜粉往往在混合制粉的过程中加入,一般采取直接加入,或通过粘接混粉技术加入,但两者均有以下局限性:1、直接加入,优势在于成本低,但若出现铜粉添加量过多的情况,则容易存在偏析情况,最终造成制品零件烧结后出现烧结尺寸稳定性差,性能偏差大,严重者会产生游离铜的现象,破坏基体组织性能;2、粘接混粉技术可有效将铜粉粘接至基粉表面,改善烧结尺寸波动大的问题,但若粘接剂挥发不完全,则容易对制品零件表面造成污染,影响外观。
发明内容
本发明所要解决的技术问题是提供一种粉末冶金用含铜铁粉,铜粉直接附着在铁粉颗粒表面,不产生铜偏析,含铜铁粉直接用于粉末冶金制品的混合制粉过程中,不需再额外添加铜粉。
为实现上述目的,本发明采用以下技术方案实现:
一种粉末冶金用含铜铁粉,其化学成分按重量百分比组成:C≤0.02%;Si≤0.030%;Mn≤0.15%;P≤0.015%;S≤0.015%;Cu8~30%;Mo0~4.0%,其余Fe及不可避免的杂质。
一种制备粉末冶金用含铜铁粉的方法,包括:冶炼、雾化、还原、退火、混料、扩散;具体步骤如下:
1)冶炼:钢液中Mo含量为0~4.0%,出钢温度:1620~1800℃;
2)雾化制粉:雾化压力10~15MPa,雾化开始温度1580~1700℃,雾化结束温度1550~1630℃、钢液流直径14~28mm、流量140~240m3/h、喷射角度30~50°;
3)还原:将上述雾化后粉体经过还原炉进行还原,还原炉还原预热段温度550~800℃,预热段行程为4~6m;高温段温度800~1000℃,高温段行程为6~12m;冷却段温度500~800℃,冷却段行程为4~8m;运行速度:90~300㎜/min;料层厚度12~48㎜;氨气流量60~190m3/h;
4)退火:将上述还原后粉体,经过还原炉进行退火处理,还原炉还原预热段温度550~800℃;预热段行程为4~6m;高温段温度800~900℃;高温段行程为6~12m;冷却段温度500~800℃;冷却段行程为4~8m;运行速度:90~300㎜/min料层厚度:12~48㎜,氨气流量60~190m3/h;出炉粉体600MPa压缩性≥7.17g/cm3;
5)混料:将退火后的粉体经过破碎、筛分、合批,然后加入0.1~2.0%比例的油性粘接剂,再加入8~30%比例电解铜粉,混料机转速控制10~20r/min,混料时间控制30~90min,制成半成品;
6)扩散:将上述半成品经还原炉扩散,还原炉扩散预热段温度650~900℃,预热段行程为2~4m;高温段温度900~1000℃,高温段行程为4~14m;冷却段温度650~900℃,冷却段行程为4~8m;氨气流量60~190m3/h,控制扩散时间60~120min,料层厚度:20~35mm,出炉制得成品。
与现有的技术相比,本发明的有益效果是:
1.本发明采用首先制备高压缩性水雾化纯铁粉,然后加入电解铜粉混合,通过高温扩散附着的方式,制备含铜水雾化钢铁粉末。
2.铜粉直接附着在铁粉颗粒表面,不产生铜偏析,而且铜粉颗粒高温扩散至铁粉颗粒表面能减少团聚,有利于改善烧结件的机械性能。含铜铁粉600MPa压缩性≥7.10g/cm3。可直接用于粉末冶金配制,不需额外添加铜粉,且保持烧结制品零件表面清洁。
3.本发明采用电解铜粉,而非雾化铜粉,因电解铜粉具有纯度高,形状呈树枝状,有利于扩散过程的均匀性;采取高温扩散方式,可使铜粉附着至铁粉颗粒面,以保证铁粉的压缩性及烧结尺寸稳定性。
