摘要： PROBLEM TO BE SOLVED: To obtain a method and an apparatus for injecting reduction material into a blast furnace with which even in the case of injecting natural gas etc., as gaseous reduction material from a tuyere of the blast furnace, coke ratio can be reduced without pressure loss. SOLUTION: In the method for injecting the reduction material, fine powdery coal and/or grain size refined synthetic resin and gaseous reduction material are injected from the separate lances in a tuyere of the blast furnace through several injecting lances 5, 7 arranged through a blowing pipe 3 of the blast furnace. Wherein, the injecting position of the gaseous reduction material is set in the range of 0-150 mm at the downstream side of the injecting position of the fine powdery coal and/or the grain size refined synthetic resin.

摘要： PROBLEM TO BE SOLVED: To provide a method for operating a blast furnace, which blows a liquid or gaseous ancillary reducing material such as fuel oil and a natural gas, which has a high heating value and does not contain ash, into the blast furnace together with a solid reducing material, but prevents the degradation of air permeability, and consequently takes out the maximum effect of charged hydrogen. SOLUTION: The method for operating the blast furnace while blowing the gaseous or liquid reducing material as the ancillary reducing material together with the solid reducing material from a tuyere includes blowing the gaseous reducing material or liquid reducing material having a ratio H/C of 1.5 or larger simultaneously with the solid reducing material, while adjusting the quantity to be blown of the solid reducing material and/or the gaseous reducing material or the liquid reducing material so that a ratio of H 2 /CO in the Bosch gas can be 0.22 or larger.
