摘要： A synthetic resin fuel for stable production of pig iron in a blast furnace. It is in the form of cylindrical pellets, each measuring X mm in thickness and Y mm in diameter, with X and Y satisfying the three expressions of 3.0≦X≦10, 2≦Y≦20, and Y/X≧1.5. The cylindrical pellets are produced by melting a resin, solidifying the melt, and cutting the solidified product. The cylindrical pellets should preferably contain more than 0.05 wt % of water. A process for producing pig iron in a blast furnace by blowing a synthetic resin fuel into a blast furnace through tuyeres, wherein said synthetic resin fuel is in the form of cylindrical pellets, each measuring X mm in thickness and Y mm in diameter, with X and Y satisfying the above-mentioned three expressions. The cylindrical pellets should preferably have a size distribution such that those having a diameter within ±20 % of the average diameter account for more than 70 wt %.
