Abstract: The invention relates to a process for manufacturing products such as bars, sections, strips, weldless tubes made of ordinary or alloyed steel, starting from an iron ore, without passing through the liquid state.This process consists in:A pre-reduced concentrated iron ore with a non-reducible oxide content of less than 1% is prepared,A homogeneous mixture of this ore is made with a lubricant, a binder and a carbonized reducer,A slab of this mixture is compacted and a complete reduction is carried out on this compacted slab under a neutral or reducer gas flow of between 1100.degree. and 1350.degree. C in order to obtain a porous steel slab,The hot slab leaving the furnace is transformed by extrusion, rolling or forging.The invention enables products of accurate analysis to be obtained with simplified installations of average capacity.
