Melting Process - The steel shall be produced by any of the following primary processes: open-hearth, basic oxygen, electric-furnace, or vacuum-induction melting (VIM). The primary melting may incorporate separate degassing or refining, and may be followed by secondary melting using electroslag remelting (ESR), or vacuum-arc remelting (VAR).

Carbon steels are those that have carbon as the main alloying element. They also contain up to 0.4% silicon and 1.2% manganese. In addition, the residual elements such as copper, molybdenum, aluminium, chromium and nickel are present in these steels.
Sponge iron and steel scrap are charged in appropriate ratio into the induction furnaces in batches. After the complete melting of charge, the hot liquid metal samples are taken to analyze the chemical composition i.e. carbon, sulphur, phosphorus, silicon
What is EN8 Carbon Steel? EN8 carbon steel is a common medium carbon and medium tensile steel, with improved strength over mild steel, through-hardening medium carbon steel. EN8 carbon steel is also readily machinable in any condition. EN8 steels are generally used in the as supplied untreated condition. But EN8 steels can be further surface-hardened by induction
Complimenting Dyson’s range of crucibles Dyson Technical Ceramics also offer thermal insulating Dypack backing material, which can be used in air and induction melting appliions. Also referred to as “Ramming Material” or “Crucible Back-up”, it creates a safety barrier in the unlikely event of …
Chemical analysis is important point which cannot be neglected. carbon percentage of the metal fed in the melting furnace are traced after completion of majority of the procedure. The induction melting furnace has completely turned the face of manufacturing processes and also various other operations.

Introduction to Surface Hardening of Steels* Revised by Michael J. Schneider, The Timken Company, and Madhu S. Chatterjee, Bodycote SURFACE HARDENING, a process that includes a wide variety of techniques (Table 1), is used to improve the wear resistance
Answer:As you most likely know, carbon, and to a lesser extent manganese, have the greatest effect Effect of Chromium on Hardenability in Medium-Carbon Steels This website requires certain cookies to work and uses other cookies to help you have the best experience.
Carpenter VIM VAR Core Iron is a low carbon magnetic iron produced using vacuum induction melting plus vacuum arc re-melting practices. Other elements commonly found in low carbon irons are held as low as possible to ensure good DC magnetic properties.
25/1/2017· • Induction melting is also well adapted to the melting of low-carbon steels, because no carbon is picked up from electrodes, as may occur in an EAF. Coreless Induction Furnaces • Both channel-and coreless-type induction electric furnaces are used in the steel industry.
Induction Furnaces As the name implies, these furnaces use induction technology with alternating electric currents to achieve the required melting temperature of the metal. Induction furnaces are widely used in foundries because they are high quality, easy to operate and energy efficient.

Cast iron is made from pig iron, which is the product of melting iron ore in a blast furnace.Cast iron can be made directly from the molten pig iron or by re melting pig iron, often along with substantial quantities of iron, steel, limestone, carbon (coke) and taking
Vacuum Induction Melting Vacuum induction melting (VIM) utilizes electric currents to melt metal within a vacuum.The first prototype was developed in 1920.One of the only ways to induce a current within a conductor is through electromagnetic induction.
Coal carbonizing agent made of high quality anthracite as raw material, is in 1300 centigrade high temperature carbonization reduce volatile, used to enhance the fixed carbon content and density, strength, oxidation resistance and products.
