How is the deoxidation work of stainless steel casting performed?

Deoxidation of stainless steel casting is usually achieved by adding a deoxidizer during the smelting process. The main function of the deoxidizer is to absorb oxygen in the molten pool and prevent oxide inclusions from appearing in the stainless steel. Commonly used deoxidizers include silicon, aluminum, titanium and Elements such as vanadium.

During the stainless steel casting process, deoxidizers are usually added to the furnace in the form of solid or powder. When the temperature of the molten pool reaches an appropriate range, the deoxidizer will react with the oxygen in the molten pool to form oxides, which will be deposited at the bottom of the molten pool .These oxides will combine with elements in the deoxidizer, thereby reducing the oxygen content in the molten pool.

The selection and addition amount of deoxidizer depends on the composition requirements of stainless steel and the casting process. Generally, the goal of adding deoxidizer is to control the oxygen content at a low level to ensure the quality and performance of stainless steel.

It is worth noting that deoxidation work is only part of the stainless steel casting process. Other factors such as alloy ratio, melting temperature and cooling rate will also affect the quality of the product. Therefore, when performing deoxidation work, a variety of factors need to be considered comprehensively. factors and proceed on a case-by-case basis.
