Plastics convert iron ore to steel Feedstock recycling in

From iron ore to steel Steel is derived from iron. However, this metal does not exist as a pure element in nature but only in chemical compounds, for the most part in an oxygenated form. This rock-like or earthy substance is called iron ore. • Iron Ore represents – according to the mining sector – an iron content of between 30 to 70 ...

Use of DRI and HBI in steel making plants

Use of DRI and HBI in steel making plants

The beginning of a melting metallurgical process is composed of the reduction of iron ore. In the BF, Cast Iron is produced and after that, by blowing oxygen in the converter, it is turned into the steel. The Direct Reduced Iron (DRI) is usually used in its briquette form (Hot Briquetted Iron (HBI)) for easier transportation and it can be ...

Iron and Steel Converting by products to feedstock Steele

Conversion — Iron- and carbon-rich fines, dust and wet sludge converted to high-quality feedstock. Mixing — Connects fine carbon particles to iron oxides for improved reduction. Binder — Less binder for more high-value metallics and carbon recovery. Sizing — Our dies ensure precise sizing, from 10-150mm, for most smelting processes.

Mild steel. Mild steel is iron containing up to about 0.25% of carbon. The presence of the carbon makes the steel stronger and harder than pure iron. The higher the percentage of carbon, the harder the steel becomes. Mild steel is used for lots of things - nails, wire, car bodies, ship building, girders and bridges amongst others. High carbon steel

Jun 21, 2018 For this reason, approx. 20 % iron scrap is added for cooling in order to protect the converter lined with stones from excessive temperatures. Iron ore or sponge iron (from the direct reduced iron process) can also be used for cooling. After 20 minutes of oxygen supply, the decarburized melt is then called crude steel.
