In layman's language, all steel other than mild steel fall under the category of special steel. But metallurgically, even mild steel/low carbon steel i.e containing less than 0.25%/0.30% carbon, may still fall under the category of special steel if any special properties is specified in the steel.

The effect of biochar substituted for anthracite as reductant on magnetizing-roasting pyrite cinder was investigated. The key of magnetizing-roasting is the gasification reaction between reductants and CO2. Since biochar could react with CO2 more rapidly at lower temperature, the reactivity of biochar is better than that of anthracite. The gasification of biochar could produce reducing ...

Anthracite As A Reductant Of Steel. Iron is a base metal extracted from iron ore.Pure iron has melting point of 1530 degree centigrade and density of 7.86 gmcc.Iron making is the process of reduction of iron ore using the relevant reducing agent reductant.It is the hot, liquid, metallic iron product obtained upon reduction of iron ore normally in blast furnace or in corex.
In 1963, the full-scale engineering study for the development of an iron, steel, and vanadium plant was initiated. This was the birth of Evraz Highveld and its process flow as it is known today.

Fine anthracite/semi-anthracite is used in the steel industry for pulverised coal injection (PCI), for sintering and briquetting and in the ferrometals market as a reductant. Steel works around the world are increasingly embracing Pulverised Coal Injection (PCI) as a way of lowering operating costs and extending the life of their coke ovens.
A variety of carbonaceous reducing materials are being used for the production of ferroalloys. Reductant materials include not just carbons such as coke, coal, char but also bio-carbons in form of ...

Preparation Plant, which, amongst others, contains the URIC (Unroasted Ilmenite Circuit) and the Reductant Preparation Plant. In the former, crude ilmenite from the separation plant is upgraded via magnetic separation technology before being fed into the furnaces. The as-received anthracite, in turn, is dried, and the fines removed before smelting.
Limonitic laterite ore, coconut charcoal, and anthracite coal were used in the process. All materials were crushed to certain particular size and then mixed to form laterite-reductant pellets. In a muffle furnace, the pellets were roasted at a temperature of 800 °C, 900 °C, and 1000 °C.
This study investigates the effect of reduction temperature (850–950 °C in steps of 50 °C), reduction time (60 to 180 min, in step of 60 min), mill scale size (800–300 μm), and mill scale ...
Material Specifications - Sunny Steel. The steelmaking process is designed to remove it as it is almost always a detrimental impurity. A typical amount in commercial steel is 0.012%, and 0.005% in formable HSLA. Silicon can be an addition or a residual. In addition, it has the effect of increasing strength but to a lesser extent than Manganese.
