Immersion Pyrometry and Open Hearth Furnace Productivity FASTER STEELMAKING AT RAVENSCRAIG
It is nowadays generally accepted that controlling the tapping temperature of steel by immersion pyrometry is an important means of improving steel quality. Broadly speaking, if the steel is too hot when tapped the ingots tend to crack, and if too cool they tend to suffer from “shell” on the surface and non-metallic inclusions beneath. From this point of view it is now simply a question of esta...
متن کاملTechnological Indicators of Operation of the Rotating-hearth Furnace in Conditions of Discontinued Production
The technological process for manufacturing seamless steel tubes in the Sisak Rolling Mill includes the heating of the charge for processing in the hearth-rotating furnace. Description of the furnace and its operation can be found in literature 1 . In the process currently applied for producing the tubes with the outer diameter of 168.3–356.6 mm the temperature is between 1280 and 1300 °C 2 . T...
متن کاملRECYCLING PRACTICES OF SPENT MgO-C REFRACTORIES
The recycling options of spent MgO-C refractories from an electrical arc furnace (EAF) have been evaluated. The economic, quality of spent refractories and products made from it, the ease of implementation of a recycling practice and the interest of steel melt shops were considered. It was decided that the best option of most EAF shops would be to recycle spent MgO-C refractory as a foaming sla...
متن کاملQuantum Theoretical studies of Nanostructures onto Hydrogen Adsorption on V-surface
We have studied the adsorption processes of H2 on the V (100) surface of Vanadium using self consistent field theory.Dissociative adsorptions of H2 are significantly favored compared to molecular adsorptions. There is a significant charge transfer from the first layer of the vanadium surface to the Hydrogen atoms. Three possible adsorption sites, top, bridge and center site, were considered in ...
متن کاملA KINETIC STUDY ON THE CARBOTHERMIC REDUCTION OF ZINC OXIDE FROM ELECTRIC ARC FURNACE DUST
In the present study, reduction of zinc oxide from the pellets made of steelmaking electric arc furnace dust has been investigated. Effects of such parameters as the type of carbon material (graphite, coke and charcoal) as well as time and temperature on the reduction reaction have been examined. The reduced (dimensionless) time method was applied to perform a kinetic analysis of the system. Ex...
