The converting process occurs in a converter. Two kinds of converters are widely used: horizontal and vertical. Two kinds of converters are widely used: horizontal and vertical. Horizontal converters of the Peirce-Smith type [ fr ] (which are an improvement of the Manhès-David converter [ fr ] ) prevail in the metallurgy of non-ferrous metals .
A Kaldo converter (using the Kaldo process or Stora-Kaldo process) is a rotary vessel oxygen based metal refining method.Originally applied to the refining of iron into steel, with most installations in the 1960s, the process is (2014) used primarily to refine non ferrous metals, typically copper.

Steel castings are used when iron castings cannot deliver enough strength or shock resistance. [ 1 ] Examples of items that are steel castings include: hydroelectric turbine wheels , forging presses , gears , railroad truck frames , valve bodies, pump casings, mining machinery , marine equipment , turbocharger turbines and engine cylinder blocks .
The Wolfsegg Iron, also known as the Salzburg Cube, is a small cuboid mass of iron that was found buried in Tertiary lignite in Wolfsegg am Hausruck, Austria, in 1885. [1] It weighs 785 grams (1 lb 12 oz) and measures 67 mm × 67 mm × 47 mm (2¾" x 2¾" x 1¾"). Four of its sides are roughly flat, while the two remaining sides (opposite each ...
The form with lutetium and lawrencium in group 3 is supported by a 1988 IUPAC report on physical, chemical, and electronic grounds, [20] and again by a 2021 IUPAC preliminary report as it is the only form that allows simultaneous (1) preservation of the sequence of increasing atomic numbers, (2) a 14-element-wide f-block, and (3) avoidance of ...
Republican presidential candidate Donald Trump pledged on Monday to rescind a Biden administration rule limiting power plant pollution and reiterated a promise to block Nippon Steel's planned ...
A swage block (or swager block) is a large, heavy block of cast iron or steel used in smithing, with variously-sized holes in its face and usually with forms on the sides. The through-holes are of various shapes and sizes and are used to hold, support or back up a hot bar of metal for further shaping.
