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。 -
Material balance and energy balance equations of complex multi - effect evaporation system were expressed in matrix equation, which has the advantages of clear structure and high modularization. by holding or omitting correlation block - matrix in matrix equation, matrix equation could be used to describe the difference of forward - feed, back - feed and cross - reed multi - evaporation system with or without solid separation, extra steam being led off to preheat material liquid, condensation water flash, or solution flash. the models include design and operation
該模型利用矩陣方程具有結構清晰和高度模塊化的特點，將復雜多效蒸發系統的物料及熱量衡算方程組以矩陣形式表達，通過保留或舍棄矩陣中特定功能模塊，模型就能代表有或無固相析出、有或無引出額外蒸汽預熱原料液、有或無冷凝水閃蒸、有或無溶液閃蒸等不同情況以及各種情況任意組合的併流、逆流、錯流多效蒸發過程，從而實現模型的通用性。
