  1. ( 2 ) the properties of the material with finer andalusite particle size are superior to those of coarse particle size at lower temperature, but properties of material of fine and coarse particle size have little difference at higher temperature. this illustrates that the andalusite particle size can lower the sintering temperature and that it brings forth not remarkable influence on the property of the material when the material is sintered completely

    ( 2 )對于不同粒度的原料,在燒成溫度較低的情況下,粒度小的材料性能明顯高於粒度大的材料,但在燒成溫度較高的情況下,兩者差別不大,說明原料粒度減小能降低製品的燒結溫度,但在制品均完全燒結的情況下對材料性能影響不大。
  2. The general characteristics of the grain - size distribution of different sedimentary facies, es pecially the variations of the parameters mz ( mean particle diameter ) and o ( standard deviation ) clearly show that the fluvio - lacustrine facies and palaeosols usually become finer in particles and worse in sorting than the aeolian sands

    該剖面不同沉積相粒度的一般分佈特徵尤其是粒度參數? mz 、的變化明顯表現出,河湖相或古土壤通常要較風成砂顆粒細化,分選相對較差。
  3. 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。
