"scrap steel"

Items tagged with scrap steel

Methods for manufacturing steel have evolved significantly since industrial production began in the late 19th century. Modern methods, however, are still based the same premise as the original Bessemer Process, which uses oxygen to lower the carbon content in iron.Today, steel production makes use of both recycled materials, as well as the traditional raw materials, such as iron ore, coal, and limestone. Two processes; basic oxygen steelmaking (BOS) and electric arc furnaces (EAF) account for virtually all steel production.

Steel is the world's most popular construction material because of its unique combination of durability, workability, and cost. It's an iron alloy that contains between 0.2 and 2 percent carbon by weight.According to the World Steel Association, in 2016 global crude steel production reached a high of 1, 628.5 million tonnes. Of this, approximately three-quarters were produced using BOS plants, while EAF facilities accounted for the remaining quarter.Some of the largest steel producing countries are China, Japan, US, and India. China accounts for roughly 50 percent of this production.The world's largest steel producers include ArcelorMittal, Hebei Steel Group, Baosteel, POSCO and Nippon Steel.

Modern steelmaking can be broken down into six steps:1. Ironmaking: In the first step, the raw inputs iron ore, coke, and lime are melted in a blast furnace.The resulting molten iron, also referred to as 'hot metal, ' still contains 4-4.5% carbon and other impurities that make it brittle.2. Primary Steelmaking: There are two primary steelmaking methods: BOS (Basic Oxygen Furnace) and the more modern EAF (Electric Arc Furnace) methods. BOS methods add recycled scrap steel to the molten iron in a converter.

Punching is performed by placing the sheet of metal stock between a punch and a die mounted in a press. The punch and die are made of hardened steel and are the same shape. The punch is sized to be a very close fit in the die. The press pushes the punch against and into the die with enough force to cut a hole in the stock. In some cases the punch and die "nest" together to create a depression in the stock. In progressive stamping, a coil of stock is fed into a long die/punch set with many stages. Multiple simple shaped holes may be produced in one stage, but complex holes are created in multiple stages. In the final stage, the part is punched free from the "web".A typical CNC turret punch has a choice of up to 60 tools in a "turret" that can be rotated to bring any tool to the punching position. A simple shape (e.g. a square, circle, or hexagon) is cut directly from the sheet. A complex shape can be cut out by making many square or rounded cuts around the perimeter. A punch is less flexible than a laser for cutting compound shapes, but faster for repetitive shapes (for example, the grille of an air-conditioning unit). A CNC punch can achieve 600 strokes per minute.A typical component (such as the side of a computer case) can be cut to high precision from a blank sheet in under 15 seconds by either a press or a laser CNC machine..
