Steelmaking is the process of producing steel from iron ore and/or scrap. In steelmaking, impurities such as nitrogen, silicon, phosphorus, sulfur and excess carbon (most important impurity) are removed from the sourced iron, and alloying elements such as manganese, nickel, chromium, carbon and vanadium are added to produce different grades of steel. Limiting dissolved gases such as nitrogen and oxygen and entrained impurities (termed "inclusions") in the steel is also important to ensure the quality of the products cast from the liquid steel.

  • Výroba oceli je metalurgický postup získání oceli, technické slitiny železa s nižším obsahem uhlíku, než mají litiny, ze surového železa odstraňováním přebytečného uhlíku a dalších nežádoucích prvků, jako je fosfor a síra, a dodáním žádoucích legujících prvků, např. manganu, hliníku, křemíku a dalších. Ocel se vyrábí ve specializovaném hutním provozu, který se nazývá ocelárna. Ocel se ve značné míře recykluje a další surovinou pro ocelárny je železný šrot.
  • Ziel der Stahlerzeugung ist es, Stahl, also Eisenlegierungen mit geringem Kohlenstoffgehalt und gewünschten Eigenschaften für das Giessen oder Schmieden, wie Bruchdehnung, Härte, Rostbeständigkeit oder Umformbarkeit, herzustellen. Den Wirtschaftszweig der Stahlerzeugung nennt man Stahlindustrie.(Siehe auch: Eisenwerk) Ein Stahlwerk ist eine Fabrik in der Metallindustrie, die zumeist mittels Hochöfen Roheisen und aus dem Roheisen dann Stahl produziert. Die Mitarbeiter eines Stahlwerks werden Stahlwerker oder Stahlkocher genannt.
  • L'acier s'élabore actuellement de deux manières : * dans un haut fourneau, à partir du minerai de fer et de coke avec réduction du carbone dans un convertisseur ; * dans un four électrique, à partir d'acier de récupération. On parle d'acier de recyclage ou d'acier électrique.
  • 製鋼(せいこう)とは、鋼鉄(鋼)をつくること。特に銑鉄を脱炭して鋼鉄をつくる工程を指す。
  • 제강(製鋼)은 철강을 제조하는 것을 말한다. 용광로에서 나온 선철에는 4% 가량의 탄소와 규소·인·망간 등의 불순물이 들어 있다. 이 선철은 단단하지만 부서지기 쉬워 주조용으로 쓰일 따름이다. 강철로 만들기 위해서는 선철 속의 탄소를 줄이고 불순물을 제거해야 한다. 용광로에서는 코크스에 의한 환원이 지나쳐서 철 속에는 탄소가 너무 많이 섞여 들었기 때문에, 이번에는 도리어 산화시킴으로써 탄소를 줄이는 한편, 불순물인 규소나 인 따위도 산화시켜 제거하여야 한다. 이를 제강이라고 부르는데, 대표적인 제강 방법으로는 평로(平爐)를 이용하는 경우와 전로(轉爐)를 쓰는 경우의 두가지가 있다.
  • Сталеплави́льное произво́дство — это получение стали из сырья, чугуна или стального лома в сталеплавильных агрегатах металлургических заводов. Сталеплавильное производство является вторым звеном в общем производственном цикле чёрной металлургии. В современной металлургии основными способами выплавки стали являются кислородно-конвертерный и процессы. Ранее использовались бессемеровский, мартеновский и тигельный процессы.

  • Pembuatan baja adalah proses untuk memproduksi baja dari bijih besi dan . Dalam pembuatan baja, seperti nitrogen, silikon, fosfor, sulfur dan kandungan karbon berlebih dikeluarkan dari , dan elemen paduan seperti mangan, nikel, kromium dan vanadium ditambahkan untuk menghasilkan berbagai . Membatasi gas-gas terlarut seperti nitrogen dan oksigen, dan kotoran terlarut (disebut "inklusi") dalam baja ini juga penting untuk memastikan kualitas produk cor dari baja cair.
