In other oxygen steel making processes and in the electric arc steelmaking process
在其它氧煉鋼和電弧煉鋼過程中作為 -
The molten steel have the same making environment at the spot, but it is subject to many factors such as temperature and killing oxygen instrument penetration ' s depth into the molten steel during the time, and killing oxygen by adding aluminum process is just one part of the whole system. consequently, in order not to interfere with next later continuing casting and other process, and to ensure the production rhythm, when the molten steel arrives at the aluminum feeding station, it cannot meet the production requirement only to sample, assay and determine the ingredient content
在實際生產中，模型是通過鋼包中的含氧量和鋼包中所需含鋁量來確定加鋁量這一函數關系的，雖然鋼水具有相同的冶煉環境，但當每一鋼包從出爐到達加鋁站進行定氧加鋁期間，會受到溫度、定氧儀探頭伸入鋼水的深度和吹氬等不同因素的影響，而且對整個煉鋼工藝來說，定氧加鋁系統只是整個生產工藝中的一部分。 -
In the process of steel - making, killing oxygen by adding aluminum process is a controlled object whose parameters are distributed and non - linear, and its observed data are discrete. the key point of this process is model of killing oxygen by adding aluminum process
煉鋼生產中，定氧加鋁工藝的被控對象具有參數分佈、非線性、動態觀測數據離散等特徵，定氧加鋁模型的建立是該工藝的核心。 -
Based on the experimental results and the correlative chemistry theory, the phases formed in the process and its influenceable factors were studied. the significant results were enumerated as follows : as for the mn - h2o system, 5g pure mn scraps ( 99. 5 %, - 200mesh ) and distilled water served as the starting materials were milled by high energy ball miller together with 200g steel balls as the milling medium. the experiments were conducted with the rotation speed of 380rpm. - mn3o4 nanopowders were fabricated after milling some time and would experienced phase transformations if continue to be milled. the reaction would be accelerated if a little of hcl or mnso4 was added while be decelerated if. a little of naoh was added. the - mn3o4 phase with particl size between 20 ~ 100 nanometer was obtained after milling 1. 5h when trace hcl was added. the oxygen added to the ball tin has little effect on the reaction
主要實驗結果如下: （ 1 ）對于mn - h2o系，通過高能行星式球磨機，在50ml蒸餾水中球磨5gmn粉末，球料比為40 : 1 ，轉速為380rpm ，球磨一定時間后獲得了納米級單相- mn3o4 。隨著球磨時間的延長，生成的- mn3o4會繼續被氧化或發生晶型轉變。加入微量hcl或mnso4會明顯加快mn的反應，加入hcl后，球磨1 . 5h后即獲得粒徑為20 100nm的單相- mn3o4粉末;加入微量的naoh會抑制mn反應生成- mn3o4 。
