Making steel. Steel is made from iron ore, a compound of iron, oxygen and other minerals that occurs in nature. The raw materials for steelmaking are mined and then transformed into steel using two different processes: the blast furnace/basic oxygen furnace route, and the electric arc furnace route.

Tata Steel has undertaken extensive research in making the process of steelmaking more energy-efficient and environmentally sustainable. From coarse and rocky iron ore to tough and shiny steel - the making of the alloy is a journey that starts from the crust of the earth, involves complex metallurgical reactions and processes, and demands technological expertise of the highest degree.
Steel making process. Steel is produced from iron ore or scrap. Iron ore is a mineral aggregate that can be converted economically into iron. The quality of the iron ore is mainly determined by its composition; a high iron content and low sulphur and phosphorus contents are favorable.

14-11-2010· The steel-making process, including steel-making and continuous casting, is usually the bottleneck in iron and steel production. Effective scheduling of this process is thus critical to improve productivity of the entire production system.
2 · Metal fabrication is a broad term referring to any process that cuts, shapes, or molds metal material into a final product. Instead of an end product being assembled from ready-made components, fabrication creates an end product from raw or semi-finished materials.
10-04-2020· According to the World Steel Association, global steel production supports or facilitates $2.9 trillion of the world's economic activity, making it a crucial material supporting millions of jobs internationally. Steel might not seem like a commodity associated with advanced technology, but its manufacturing process has come a long way.

21-06-2018· This also makes it possible to melt high-melting alloying elements in scrap such as tungsten, molybdenum and niobium. In principle, all types of steel can be produced with the electric steel process, although the electric steel process is usually reserved for high-alloyed steels due to the high costs involved (e.g. tool steels).
There are two main processes for producing steel: by means of a blast furnace (= indirect reduction) in combination with a converter, or by means of an electric furnace. In the former process, iron ore is the main raw material. In an electric furnace, scrap iron is used and occasionally also sponge iron.
The figure shows a flowchart of the integrated manufacturing process for iron and steel using the blast furnace and basic oxygen furnace (denoted BF and BOF hereinafter, respectively), which is presently the most commonly used method (51% of world steel production).
10-10-2016· Metallurgical Processes and Defects in Steel Products . Defects in steel products are defined as deviations in appearance, shape, dimension, macro-structure / micro-structure, and/or chemical properties when compared with the specifications given in the technical standards or any other normative documents in force.
20-09-2016· Building a stainless steel product from the ground up involves a lot of work, technology and science. Even though there are billions of users of stainless steel items around the world, there are very few people (relatively) who know what goes into making a stainless steel product from scratch. The manufacturing process of a stainless
Making steel. At Scunthorpe, we use the Basic Oxygen Steelmaking (BOS) process – our modern convertors (or vessels) take a combined charge of scrap and liquid iron of up to 330 tonnes and convert this into steel in just 25 minutes. When the liquid iron arrives at the BOS Plant, it's poured from the torpedoes into refractory-lined charging ...
The steel product is tapped by opening a hole in the base of the furnace with an explosive charge. The open hearth steelmaking process with oxygen lancing normally requires from 4 to 10 hours for each heat. 12.5.1.7 Semifinished Product Preparation - After the steel has been tapped, the molten metal is teemed (poured) into ingots which are
