Steel Stirring Methods in Secondary Refining

Stirring is an essential operation in secondary steelmaking. By creating controlled circulation within molten steel, it improves heat and mass transfer, resulting in more uniform temperature, consistent chemical composition, and better steel cleanliness. Depending on the refining process, stirring can be achieved mechanically, by gravity, through gas injection, or by…

Billet Reheating: Avoiding Defects

During the billet heated, operators should take measures to prevent following case happening. Overheating When the steel billet is heated for a long time at high temperature, it is very easy to overheat. The overheating phenomenon of steel billet is mainly manifested in the excessive growth of the microstructure grains…

Initial Use of Induction Furnace

It is quite important to operate a new induction furnace correctly, that could affect the service life of the induction furnace. The new furnace should be continuously smelted as much as possible to avoid thermal shock damage caused by intermittent melting and hot and cold, and generally should be continuously…
