上吹転炉における脱燐平衡

SchenckおよびHerasymenkoの平衡の適用

抄録

The authers applied the dephosphorization equilibrium formulas reported by Schenck and Herasymenko to the final slag and metal of the 3-ton experimental LD converter.
The results obtained were as follows.
(1) The observed values of logK^IV_P in the Schenck's formula had a linear relation to 1/t, but they located in the upper region against the Schenck's equilibrium.
(2) Assuming, the next formula was obtained
(3) had a maximum value on the value of 25-30% of (T. Fe).
(4) In the Herasymenko's formula, linear relation was obtained between logK^P_Fe and Ca⁺⁺ and this relation was expressed as follows,
This formula had a deviation from the open-hearth formula reported by Herasymenko. This meant that the dephosphorization of an LD converter did not approach closer to the equilibrium than open-hearth furnaces.
