| 摘 要： | 本文研究了用不锈钢粉末轧制多孔生带材,经烧结、卷曲和焊接等工艺生产多孔管材的方法。粒度大于5mm的气体雾化不锈钢丸经涡旋研磨机破碎成粒度组成为-100+250目的不锈钢粉末,再用上述工艺获得壁厚为0.8-1.2mm的多孔不锈钢管。其相对渗透性可达(3~7)×10-3L·N/cm2·min·mmH2O,平均孔径为6-15μm。

| Abstract: | The present paper studies processes for producing porous stainless steel tubes by rolling stainless steel powder and followed by sintering, winding, welding, etc.The gas atomized stainless steel shots having a particle size over 5mm were crushed into powders of -100+250mesh by Eddy rotary mill. The thickness of stainless steel tube was 0.8-1.2mm. The average diameter of the pores of porous stainless steel tubes was 6 to 15μm. The relative permeability of the porous stainless steel tube for nitrogen was (3~7)×10-3L·N/cm2·min·mmH2O. |
