Before recarburizer is completely dissolved, the stirring time is long and the absorption rate is high. Stirring is beneficial to the dissolution and diffusion of carbon, reducing recarburizer floating on the surface to be burned.
Stirring can also reduce carbonation heat preservation, shorten production cycle and avoid burning alloying elements in molten iron. However, if stirring time is too long, which not only has a great influence on the furnance service life, but also causes carbon loss after the recarburizer is dissolved. Therefore, a suitable stirring time of molten iron to ensure complete dissolution of recarburizing agent is important .
