In principle, steelmaking is a melting, purifying, and alloying process carried out at approximately 1,600° C (2,900° F) in molten conditions. To create pure steel, the products that go into it- lime, coke and iron ore- must be made into iron. Let’s look at this incredible process. The resulting red hot molten iron contains 4-4.5% carbon and other impurities Design of synthetic slag. Today, however, it is also employed in making more widely used steels, including alloy and stainless grades as well as some special carbon and low-alloy steels. In this step, the rough cast items are formed into shapes through a process called hot rolling. Slag design in secondary metallurgy is crucial for the performance in steelmaking. ELECTROPLATING PROCESS Electroplating is an electrolytic process for depositing a layer of metal upon a substrate to enhance the appearance or properties of the component. Strength wise there is no major difference if the secondary steel passes the physical and chemical test both are same. Alloy steels are fully killed to obtain maximum recovery of alloying additions.
