For Steel Making Ferro Silicon Aluminum

It is also proved to be a very effective method to use aluminum iron and other aluminum alloys for deoxidation. Not only the aluminum consumption is greatly reduced, but also the amount of aluminum added can be controlled more accurately, and the content of non-metallic inclusions is also reduced. As a new composite deoxidizer in the past two years, iron has not only achieved obvious aluminum-saving effect (40-50% higher than that of pure aluminum) under the premise of ensuring the same final oxygen content level and mechanical properties of steel as pure aluminum deoxidation. %), and the pouring performance of some molten steel is improved, and the phenomenon of nodulation at the nozzle is greatly reduced.
