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
本文系統研究了水霧化預合金鋼粉生產工藝及合金化方法對鐵基粉末冶金材料性能影響，詳細研究了冶煉、霧化、還原工藝參數對預合金鋼粉化學成份和物理性能影響，並得出如下結論： （ 1 ）採用高壓水霧化技術可用於生產高密度、高強度、尺寸穩定性的低氫損含量的水霧化預合金鋼粉。 （ 2 ）冶煉溫度越高，高壓水壓力越大，所得生粉顆粒粒度越細。 （ 3 ）水錐角調整在一個適當角度范圍內可獲得粒度組成較好的生粉。 -
In this paper, systematic numerical test have been carried out to study the stability of surrounding rock mass with different distribution of weak interbed, different distance between weak interbed and limit of excavation, different thickness of weak interbed, in the different confining coefficient and representational surrounding rock mass graded ii, iii, iv. all of the numerical modeling is plain - strain type with elastic - plastic constitutive law and mohor - coulomb failure criterion, through the integrated numerical analysis program final. plentiful numerical test results have been drawn via analyse the deformation, tensile stress region, plastic region of surrounding rock and the stress status of shot - crete
