powdered alloy steel
Examples
- Water atomized pure iron powder and alloyed steel powder for powder metallurgy
粉末冶金用水雾化纯铁粉合金钢粉 - The conclusions are as follows : ( 1 ) high - pressure water - atomization can be used to produce a pre - alloyed steel powder with high apparent density , high green strength , size - stability after sintering and low hydrogen - loss content ; ( 2 ) the higher smelting temperature and / or water pressure , the finer particle size of steel powders ; ( 3 ) when the atomization angle holds in a reasonable value ' s range the obtained powder will have a better particle size distribution ; ( 4 ) an optimum atomization technological parameters : liquid steel flux , water pressure and water prick angle was obtained ( 5 ) reduction variables ( temperature , holding time , material - bed ' s thickness and reducing gas flux ) have a significant effect on the particle agglomeration and properties of final powder was given ( 6 ) different alloying methods were developed to modify properties of ferrous powder materials and hence to broaden its applications in ferrous powder metallurgy industry
本文系统研究了水雾化预合金钢粉生产工艺及合金化方法对铁基粉末冶金材料性能影响，详细研究了冶炼、雾化、还原工艺参数对预合金钢粉化学成份和物理性能影响，并得出如下结论： ( 1 )采用高压水雾化技术可用于生产高密度、高强度、尺寸稳定性的低氢损含量的水雾化预合金钢粉。 ( 2 )冶炼温度越高，高压水压力越大，所得生粉颗粒粒度越细。 ( 3 )水锥角调整在一个适当角度范围内可获得粒度组成较好的生粉。
