Iron Making Boundless World History

Carburization is a heat treatment process, in which iron or steel absorbs carbon while the metal is heated in the presence of a carbon-bearing material, such as charcoal or carbon monoxide. The intent is to make the metal harder. Unlike modern steel making, the process increased the amount of carbon in the iron.

The Making of Iron Steel

2020-8-3  Iron ore, as mined, is a combination of iron with oxygen and various other unwanted substances, generally known as "gangue". The first metallurgical step is to reduce iron ore to metallic iron, a process which is mostly carried out in a blast furnace, using coke as both a fuel and reducing agent.

Process monitoring of iron-making process in a blast ...

2016-2-1  The main focus of this paper is studying the process monitoring and abnormality detection of the iron-making process in blast furnaces using PCA-based techniques. To cope with the non-normality of the process data, a new method called the static convex hull-based PCA algorithm (SCHPCA) using the geometry modeling of principal scores is proposed.
