PURPOSE:To obtain a particle uniformizing agent of an iron-manufacturing powdery stock material manifesting excellent particle uniformizing property in the addition of a small amount and excellent in a handling property and workability, consisting of a water-soluble or water swellable cellulosic high-molecular powder and a clayed powder. CONSTITUTION:A particle uniformizing agent, which contains a water-soluble or water-swellable cellulosic high-molecular powder such as carboxy methyl cellulose or methyl cellulose and a clayed power such as sodium bentonite or calcium bentonite in a weight ratio of 8:2-2:8, pref., 7:3-3:7 and usually contains 2- 15wt% of water, is added to an iron-manufacturing powdery stock material such as powdery cokes in a range of 0.1-1.5wt%.
