Ingot Casting : Process Description\n\n After it is refined, the molten steel is tapped into refractory lined ladles. The steel is then teemed (poured) into a series of ingot molds. After the ingots solidify, the ingot molds are stripped and the ingots are placed in soaking pits for heating and to equalize the internal and external temperature. Following the soak, the ingots are hot rolled in large primary rolling mills to produce slabs, blooms, or billets depending on the final products desired.\n\nMore info in link below:

Part of the downfall of USX,(US Steel) was the little companies specialized in doing high quality, specialized steel and alloys. Bethlehem steel kept wanting to make more and the old fashion way. \nLow tech side. I have heard of steel studs for houses. They are put together like an erector set. Wood business wants to steel more wood and would not have thought of doing that. I worked with a group making new wires and diffusion barriers for semiconductors. Copper is conducts faster, but diffuses more for example. Gold is used on the outside since it doesn't corrode. \nPerhaps a solar, induction furnace to melt down old cars, cans? Non Pt, catalytic converter?\nFind a need, replace something for efficiency,

Previously cast iron was used. Now its Aluminium. Work is going on a Ti-Mg alloy.

With advances in plastic technology, plastic is replacing metal in many places based on cost, weight and/or resistance to corrosion etc.

Looks like it is separated out by hand.  The ore is passed under an ultraviolet light in a darkened area.

Most world class businesses use Lean Manufacturing techniques. You can find a good definition of what this involves in Wikipedia.

I think it's these metals chrome, cobalt, titanium, or ceramic materials can be used.  I think they have recalled ceramic because they were cracking though.

A foundry is a place where castings are made from molten metal according to an end user's specifications. This basic metal distinction between foundries fall under ferrous (iron or steel) and non-ferrous (aluminum, brass, bronze, copper etc.)

Most refiners do not just take metal sweeps from dental floors. The vast majority of refining scrap come from jewelry and ornament fabricators using gold, silver, and platinum.\n\nTry the refiner at the link below. Very reputable and I have used their services for many years.

You basically need information on metal manufacturing, casting, and molding.  Not really something that can be done at home.

Welders use plasma arcs all the time to cut metal\nyou could probably go see this in action at \na body shop, exhaust repair, or steel fab plant\nor even at your school possibly

Cellular manufacturing is arranging manufacturing processes to become directly sequential, rather than by building batches of inventory between operations.\n\nSo if a sequence of operations is to forge, broach and then polish, a cell would have a forge hammer sitting next to a broach sitting next to a polish machine. All three operations would be performed on the part before it is dropped into a bin.\n\nThe advantages are less floor space and higher productivity (for you 6-sigma types - lower "tack time"). The disadvantage and limitations are higher capital investment and physical arrangement of dangerous or large equipment.\n\nThe URL has a white paper on Cellular Conversion.

The metal starts as flat piece of aluminum. The sheets are placed into a die and drawn to proper depth. The tops are made out of  blank sheet of metal and through a multi strike process are formed. They then go to a secondary process that places the tabs on the lids. They are assembled by seam locking (rolling the top small lip over a flange on the can) then is spun in a curling station to form a perfect seam. Any imperfection in the height of the can is hidden by the seam locking process.  The cans are then painted in a series of single ink applications over a template. The cans are then shipped out to the beverage factories.

1) German silver  \nGERMAN SILVER [German silver] name for various alloys of copper, zinc, and nickel, sometimes also containing lead and tin. They were originally named for their silver-white color, but use of the term silver is now prohibited for alloys not containing that metal. German silver varies in composition, the percentage of the three elements ranging approximately as follows: copper, from 50% to 61.6%; zinc, from 19% to 17.2%; nickel, from 30% to 21.1%. The proportions are always specified in commercial alloys. German silver is extensively used because of its hardness, toughness, and resistance to corrosion for articles such as tableware (commonly silver plated), marine fittings, and plumbing fixtures. Because of its high electrical resistance it is used also in heating coils. It was discovered (early 19th cent.) by a German industrial chemist, E. A. Geitner. \n\n2) galvanizing  \nGALVANIZING [galvanizing] process of coating a metal, usually iron or steel, with a protective covering of zinc. Galvanized iron is prepared either by dipping iron, from which rust has been removed by the action of sulfuric acid, into molten zinc so that a thin layer of the zinc remains on the surface of the iron upon removal or by a method of electroplating. Iron is also coated with zinc by a method in which the iron is first covered with the zinc dust and then baked; an alloy is formed at the surface, the resulting product being known as sherardized iron. Sheets of pure iron, copper iron, and various steels, as well as wire and netting, are often galvanized, since the zinc coating resists oxidation and the action of moisture very successfully. When the coating is broken or pierced some protection is still afforded, since the zinc reacts with the corroding agent first.
