Secondary refining's development

In order to homogenize the composition and temperature, the gas stirring process in the ladle appeared. The most striking is the adoption of secondary refining, which greatly improves the output and quality of steel. However, what is the main task and purpose of secondary refining? The composition of molten steel, decarburization, deslagging and refining of molten steel shall be adjusted according to the target of molten steel, molten steel melting, deslagging and refining.
