Abstract
The article off ers a short review of iron and steel production history. The new metallurgy – metallurgy under [gas] pressure (MP) comes into existence at the end of 20th century and in authors’ opinion even at this early stage of its development MP is already showing many advantages to both conventional metallurgy (CM) and vacuum metallurgy (VM) such as: increase of the yield strength in four times with the rest of the uniquely retained steel properties; decrease or complete elimination of some expensive alloying elements (Ni, Mo, Co, W, etc.); possibility of using unconventional alloying elements (Ca, Zn, Pb, etc.); being highly ecological; its stable development, etc. Because of that it is to be expected that the development of MP will lead to a breakthrough in the areas of quality and special metallurgy. Out of all known to date MP methods, big steelmaking bath (BSB) process is considered to be the most promising of all.
