Vanadium processing | Britannica
· Vanadium processing, preparation of the metal for use in various products. Vanadium (V) is a grayish silver metal whose crystal structure is a body-centred cubic (bcc) lattice, with a melting point of 1,926 C (3,499 F). The metal is used principally as an alloying
Slag Studies begins to unpack the modes of production for which the artist is renowned. In a suite of photographic works, North depicts the industrial process of extracting iron, rendered moodily dark and foreboding, with machinery moving to tip molten slag into a churned landscape.
Steelmaking slag (BOF and EAF) is cooled similarly to aircooled BF slag and is used for most of the same purposes. As the production process varies at this stage depending on the type of steel being made, the resulting slags also have diverse chemical properties making them more difficult to use than ironmaking slags.

Slag returning process of raising the amount of treated …
Abstract The slag returning process of raising the amount of treated industrial effluent in coal-water fluid method is to return partial flyash to the compounding of coal-water fluid so that small amount of coal is made to burn industrial effluent as much as possible.
The first step in the process is transferring the waste from the waste pit to the combustion chamber. The combustion process creates slag, which is collected in a slag pit. Rising flue gases enter a boiler where they generate electricity via a turbine. A filtering system intensively cleans the remaining flue gas and releases it into the ...
Deoxidation Mechanism of Al-Killed Steel during Industrial …
In the real industrial production process, the refining slag would contact with atmosphere, so the oxygen in air is an important oxygen source. It is well known that Fe 2 O 3 is more stable than FeO, therefore at high temperature of steelmaking, FeO in slag would be easily oxidized by the oxygen in air.

Industrial Welding Processes
· The slag layer needs to be removed after welding. Welds are typically not as clean or neat as other methods and molten splatter and slag inclusions in the weld make this process unsuitable for some applications. The process is commonly used on construction
· Slag is a by-product of the metallurgical smelting process. Slag has a double role: it permits removal of impurities, known as gangue, from the melt by forming oxides. It also allows exchange reactions with the liquid metal, permitting control of the process in order for the desirable elements to stay in the melt while the others are removed.

Creating Steel | HowStuffWorks
The open-hearth furnace is one way to create steel from pig iron. The pig iron, limestone and iron ore go into an open-hearth furnace. It is heated to about 1,600 degrees F (871 degrees C). The limestone and ore form a slag that floats on the surface. Impurities, including carbon, are oxidized and float out of the iron into the slag.
