The invention relates to a method of reducing furnace temperature in a blast furnace. The method comprises the following steps that (1), furnace temperature is reduced, and when the furnace temperature is greater than or equal to 0.07%, the furnace temperature is reduced by reducing the fuel ratio by 4-6 kg every four hours; (2), furnace temperature is controlled, and when the furnace temperatureis in the range from 0.55% to 0.69%, the furnace temperature is reduced by reducing 4-6 kg for the first four hours and slightly calling back by 2-3 kg for the later four hours; and (3), the fuel ratio is determined, and when the furnace temperature is 0.45% + / - 0.05% in two heats, the average fuel ratio of the first eight hours is taken as the fuel ratio controlled during smelting. The method ofreducing furnace temperature in the blast furnace can reduce the consumption of ironmaking fuel and reduces the cost of ironmaking.
