The difference between AOD furnace and ordinary converter

 1. AOD generally uses side and bottom combined blowing, and ordinary converters generally use top and bottom combined blowing;

2. AOD furnace also has top and bottom blowing;
3. The ordinary converter plays the role of removing carbon and adjusting other components in the process of making ordinary steel. Generally, the molten iron comes out of the converter as molten steel;
4. AOD furnace is mainly used for the continuous refining of ordinary molten steel, and is often used to smelt stainless steel and low carbon steel;
5. For the first decarburization in the converter, one of the main contradictions in stainless steel smelting is that it can decarburize while retaining chromium during further decarburization. AOD and VOD retain chromium in different ways.
