Direct reduced iron process

Direct reduced iron (DRI) process. In addition to the process route via the blast furnace process, there is another option for extracting crude steel from iron ores using the so-called direct reduced iron (DRI) process (secondary route). The starting point for the efforts to find an alternative to the blast furnace process was the relatively ...

What is Powder Metallurgy?- Definition, and Process

Powder metallurgy is a term covering a wide range of ways in which materials or components are made from metal powders. This process can avoid, or greatly reduce, the need to use metal removal processes, thereby drastically reducing yield losses in manufacture and often resulting in lower costs. Powder metallurgy is a metal forming …

Describe what is happening during the phase of the cardiac action potential labeled 2 in the diagram. Phase 2 is the plateau phase which occurs due to opening of slow voltage-gated calcium channels, which allow continued inflow of Ca2+ from ICF into the cytosol. This continuous inflow of Ca+2 causes sustained depolarization of the cardiac ...

Blending Process In Refinery – Equinox

Blending is the last step in the refining process that mixes the optimal combination of components (among various petroleum streams) to produce the final finished product.

10.3: Phase Transitions

The process of a solid becoming a liquid is called melting (an older term that you may see sometimes is fusion). The opposite process, a liquid becoming a solid, is called solidification. For any pure substance, the temperature at which melting occurs—known as the melting point—is a characteristic of that substance. It requires …

There are two ways in which hydrogen can be used in steel production: Hydrogen can be used as an auxiliary reducing agent in the BF-BOF route (H2-BF) Hydrogen can be used as the sole reducing agent in …

Smelting

Smelting is a process in which the base metal is extracted from the ore by applying heat to it. It is one kind of extractive metallurgy. It is used for the extraction of many metals like copper, aluminium, iron, silver, lead and many other base metals from their respective ores. For the decomposition of the ores, smelting uses heat and chemical ...

Rusting of Iron: Explanation, Chemical Reaction, Prevention

The process of rusting of iron pertains to the occurrence of rust, which is a composite of iron oxides, on the exterior of iron-based items or constructions. The formation of rust occurs as a result of a Redox Reaction between oxygen and iron within a water-rich environment, such as air with elevated moisture levels.

Blast furnace process

Combustion process. The iron in the processed ores must be dissolved out by chemical processes. This requires an element that binds oxygen more strongly than iron. This is exactly what carbon can do as a reducing agent. The carbon is fed to the blast furnace in the form of coke ( pyrolyzed coal) from the coking plant.

Fertilizer Blending: Embracing Technology Through Automation

"A blend system that only turns on, blends a load of fertilizer, and loads the blend on a truck or in an overhead tank is not a fully automated/integrated system," he says. "Systems that only do one part of the process and require a person's time entering orders into the blend system or typing orders into an accounting program are not ...

The Iron Age was a period in human history that started between 1200 B.C. and 600 B.C. During the Iron Age, people across much of Europe, Asia and parts of Africa began making tools and weapons ...

5 Tips On How To Make The Dispatch Process More Efficient

1. Get your dispatch process right . To avoid confusion and prevent reporting errors, define your dispatch process and make sure everyone in the warehouse is following it. Make sure workflows are documented and that staff are provided with adequate training so that everyone is on the same page. 2.

What happens during the process of smelting of iron?

In the smelting of iron, the iron oxide ( F e2O3) present in the iron ore loses its oxygen. This results in the iron that is obtained from the process to be less in weight compared to the weight of iron ore used before the process. Therefore losing oxygen was defined as the process of reduction as iron ore lost its weight in the smelting ...

Powder Metallurgy — Engineering Notes

Sintering Process. The sintering process improves the mechanical and physical properties of the green compact. The heat applied is around 0.7 of the absolute melting temperature of the powder. The process will cause the metal powder compact to shrink and bond by diffusion. The shrinkage will cause an increase in the density of the part.

Photosynthesis

Most life on Earth depends on photosynthesis.The process is carried out by plants, algae, and some types of bacteria, which capture energy from sunlight to produce oxygen (O 2) and chemical energy stored in glucose (a sugar). Herbivores then obtain this energy by eating plants, and carnivores obtain it by eating herbivores.. The process. …
