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。
