A thermodynamic modeling is developed for slag-metal equilibration in LF, deoxidation control of the melt and prediction of composition of oxide inclusion in steel based on the sub-regular solution model of multi-component system.

slag containing alkali metals at 1500 ℃ was studied using gas-slag equilibrium technique.

In order to reduce harmful effect of alkali metals on blast furnace operation,improve the alkali capacity of BF slag,the potassium capacity of BF slag was studied at 1723 K using gas-slag equilibrium technique.

Improving metal balance management level in nonferrous smelting enterprises by relying on technological progress;

The sources of the various branch errors of metal balance in concentrator production are quantitatively analyzed on the basis of the operation experience for many years,and some easily neglect problems in concentrators are pointed o.

The application in Bali mill approves that bilmat can effectively improve the data\'s accuracy and reliability which results in better metal balance.

The method gives the verification of accuracy of raw lead and insures the balance of gold and silver in leadsmelting process.
