The War Raw Materials Department (Kriegsrohstoffabteilung or KRA) was set up few days later. This department was led by Rathenau himself, who chose his colleagues as the industrial and financial leaders. They were in charge of controlling the requisitioning and allocating of raw materials needed by the armament industry.
Nov 19, 2018· Raw materials For the production of steel, there is a need for iron raw material in the form of iron ore or scrap metal, together with alloying elements so that the material acquires the desired for properties. In the production of ore-based steel, coal is also needed as a reducing agent and limestone as a slag former.
During the period of the industrial revolution, as demand for coal soared thanks to iron and steam, as the technology to produce coal improved and the ability to move it increased, coal experienced a massive escalation. From 1700 to 1750 production increased by 50% and nearly another by 1800.
