(1) Increase the furnace temperature to increase the equilibrium constant of the chemical reaction.
(2) Reduce the Cr2O3 content in the slag and maintain a higher melting point during the production process. The level of Cr2o3 content reflects the degree of reduction of useful elements. A lower Cr2o3 content means that various reactions in the furnace are carried out more thoroughly, and the reducing agent coke is excess. In actual operation, it is more beneficial to the desulfurization effect to properly control the melting point of the slag, avoid operations with too low a melting point, and ensure sufficient dosage of reducing agent. However, the melting point of the slag should not be too high, otherwise the slag will become sticky and the slag iron will overheat, causing the furnace condition to deteriorate.

(3) Increase the alkalinity of the slag, that is, increase the cao content in the slag, reduce the viscosity of the slag, and increase the conductivity of the slag. The increase of both can improve the kinetic conditions of the reaction in the furnace, ensure uniform power distribution in the furnace, and expand Crucible, but at the same time, there are also unfavorable factors such as excessive electrode consumption, reduced slag hanging on the furnace wall, and heat loss.
(4) Increase the percentage content of c and si in the alloy, select appropriate chromium ore and control the appropriate melting point of slag.

(5) Sometimes adding desulfurizers such as lime to the molten iron ladle also has a certain effect.
(6) After adding lime, the melting point of the slag is lowered, which ultimately leads to carburization of the alloy and also reduces the chromium recovery rate.
