    en.wikipedia.org/wiki/Engineering_design_process

    The engineering design process, also known as the engineering method, is a common series of steps that engineers use in creating functional products and processes. The process is highly iterative – parts of the process often need to be repeated many times before another can be entered – though the part(s) that get iterated and the number of such cycles in any given project may vary.

    en.wikipedia.org/wiki/Water_jacket_furnace...

    The design of water jacket furnaces differ from the conventional blast furnaces used for smelting iron ore, which use a hot blast. Water jacket furnaces typically used a cold air blast, typically provided by a positive-displacement blower, such as a Roots blower. Preheating of the air blast was used on some water jacket furnaces. [15]

  5. Process design - Wikipedia

    en.wikipedia.org/wiki/Process_design

    In chemical engineering, process design is the choice and sequencing of units for desired physical and/or chemical transformation of materials. Process design is central to chemical engineering, and it can be considered to be the summit of that field, bringing together all of the field's components.

  6. Metallurgy - Wikipedia

    en.wikipedia.org/wiki/Metallurgy

    Metallurgy derives from the Ancient Greek μεταλλουργός, metallourgós, "worker in metal", from μέταλλον, métallon, "mine, metal" + ἔργον, érgon, "work" The word was originally an alchemist's term for the extraction of metals from minerals, the ending -urgy signifying a process, especially manufacturing: it was discussed in this sense in the 1797 Encyclopædia ...

  7. Refining (metallurgy) - Wikipedia

    en.wikipedia.org/wiki/Refining_(metallurgy)

    In metallurgy, refining consists of purifying an impure metal. It is to be distinguished from other processes such as smelting and calcining in that those two involve a chemical change to the raw material, whereas in refining the final material is chemically identical to the raw material. Refining thus increases the purity of the raw material ...
