Steel Industry Furnace Q) What's the difference between an alloy and an ore? An alloy is a homogeneous mixture of elements; at least one of the elements must be a metal. An ore is a naturally occuring mixture (usually heterogenous) that contains a particular metal (or a compound of that metal) in amounts that make extraction of the metal economically worthwhile. Q) Can you recycle steel? Q) How many different types of steel are available? Q) How much steel is produced in a year? Q) Is steel environmentally friendly and sustainable? Q) What is a finished product? Q) What is a flat steel product? Q) What is a long steel product? Q) What is a mini-mill? Q) What is a semi-finished product? Q) What is blast furnace iron (BFI)? Q) What is direct reduced iron (DRI)? Q) Where is steel produced? Q) Who invented steel? Q) Why does steel rust? Q) Where are the galvanised plain and corrugated steel sheets, rods and wires produced? Q) What is TMT bar? Q) What is the difference between TMT, HYSD, TOR steel? Casting Superalloys Brazing |

Q) How does steel become stainless? A: Adding 10 to 30 percent chromium to steel creates stainless steel, which is very resistant to rust. Q) Do you manufacture aeronautical grade of alloys? Q) What is iron ore? Q) Have you ever wondered how people refine iron and steel? You probably have heard of iron ore, but how is it that you extract a metal from a rock? Q) How Do We Mine Iron Ore? To make iron, you start with iron ore. Iron ore is simply rock that happens to contain a high concentration of iron. Common iron ores include: Hematite - Fe2O3 - 70 percent iron Magnetite - Fe3O4 - 72 percent iron Limonite - Fe2O3 + H2O - 50 percent to 66 percent iron Siderite - FeCO3 - 48 percent iron If you had to pick a few technologies that have had a tremendous effect on modern society, the refining of iron and steel would have to be somewhere near the top of the list. Iron and steel show up in a huge array of modern products. Cars, tractors, bridges, trains (and their rails), tools, skyscrapers, guns, ships -- even the common steel can -- all depend on iron and steel to make them strong and inexpensive. Basic shapes such as plates, sheets, strips, rods, bars, and tubing. This industry also uses blast furnaces and coke ovens. Occupational Safety and Health Administration What OSHA standards apply?
