This invention provides a method for evaluating the cost-effectiveness of semi-coke based on the effective calorific value of pulverized coal, relating to the field of iron and steel metallurgy. First, a formula for calculating the effective calorific value of pulverized coal in a blast furnace is established. By calculating the heat released from incomplete combustion of carbon and deducting the heat absorbed by moisture decomposition, hydrocarbon cracking, ash slag formation, and desulfurization, an effective calorific value more consistent with the actual operating conditions of the blast furnace is obtained.
