Dynamics Research of Direct Alloying Smelting Boron Steel
The direct alloying melting of boron steel was analyzed from dynamics, the dynamical model was analyzed in the two processes of boron oxide and carbon reaction during boriding dissolving of pure iron and convicting of slag iron,and the method to solve melting rate of pure iron and the relationship between the reduction rate of boron oxide and the slag diameter and the residence time of the slag to float on the liquid were obtained. The experimental results show that,when the diameter of the slag is certain, the longer the residence time, the higher the reduction rate, and when the slag remains in the iron liquid for a certain time, the smaller the diameter of the slag, the higher the reduction rate.
