The invention belongs to the technical field of blast furnace long-life furnace protection, and particularly relates to a titanium-containing material furnace protection economic evaluation model. Thetitanium-containing material furnace protection economic evaluation model is characterized in that the titanium content in furnace slag is obtained through calculation by obtaining the titanium distribution ratio maximum value and the titanium content lower limit in iron melt; further, the furnace protection economic titanium load is calculated through titanium balance according to the titanium content lower limit of the iron melt and the titanium content in the furnace slag; under the condition that the consumption of basic raw materials is not changed, the blast furnace protection cost is calculated. The titanium-containing material furnace protection economic evaluation model has the advantages that the economical performance of titanium-containing materials can be systematically evaluated; the guide is provided for selecting economic and efficient titanium-containing materials for ironmaking operators.
