Fluid Flow, Flow Control and Modifying Devices in a Tundish For the transfer of liquid steel from a steel teeming ladle to the moulds of a continuous casting machine (CCM), an intermediate vessel, called a tundish, is used. The tundish is intended to deliver the liquid steel to the moulds evenly and at a designed …
Read MoreSteel Welding Electrodes Welding is the strongest method for bonding metal to metal. It is a process for joining or fastening two pieces of similar metals (work pieces) by melting and fusing (i) the base metals being joined, and (ii) the filler metal applied. Welding can be done without the use of a filler metal …
Read MoreSlopping of Slag in Basic Oxygen Furnace Steelmaking in basic oxygen furnace (BOF) is a batch process in which steel is made from liquid iron. The concentration of elements such as carbon (C), manganese (Mn), and phosphorous (P) have an impact on the steel quality. For the steel to be cast, it needs to be …
Read MoreEffect of Alkalis on Ironmaking Process in a Blast Furnace One of the main objectives during the operation of a blast furnace (BF) is to maximize the production of hot metal (HM) of the desired chemical composition at the minimum costs. This needs a high quality of a raw material base and a regular, smooth …
Read MoreSteel Cleanliness and Clean Steel Technologies Steel cleanliness is an important factor which decides the quality of the steel. It can have a remarkable influence on steel properties, such as tensile strength, formability, toughness, weldability, cracking-resistance, corrosion resistance, and fatigue-resistance etc. The demand for better mechanical properties of steels from the steel consumers has urged …
Read MoreElectroslag Remelting Process Electroslag remelting (ESR) is the abbreviated name given to electroslag consumable electrode remelting and secondary refining process. It is a secondary steelmaking process which is used for remelting and refining of steels and special alloys normally used for critical applications in aircraft, thermal and nuclear power plants, and defence hardware, etc. The …
Read MoreUtilization Optimization of Ferroalloys during Steelmaking Ferroalloys are alloys of iron with a high percentage of one or more of other elements such as silicon (Si) and manganese (Mn) etc. They are brittle and unsuitable for direct use in fabricating of products of use. Ferroalloys are important raw materials for the steelmaking process. They are …
Read MoreProduction of Steel in Induction Furnace Medium frequency coreless induction furnace is generally used for the production of steel in the steel melting shops of low capacity. The induction furnace is equipped with a converter for producing the necessary medium frequency from the 50 Hz frequency of the power supply. For this, a direct voltage …
