Topics in Cement and Concrete Research [PDF]
, 2006 In recent decades, the construction sector has faced many changes. One of these changes is the shift in the role of national government from one-sided practices in which the government was solely responsible for strategic and long-term spatial planning ...

steel research international, EarlyView.The melting behavior of hot briquetted iron (HBI) is observed and compared with FactSage computing simulation. When using HBI in an electric arc furnace process, a proper design of intrinsic carbon content in HBI, charging ratio of HBI, and addition of lime are proposed to be essential to control the slag volume, maintain slag basicity, and mitigate ...

The Rate of Boron Removal from Molten Silicon by CaO-SiO2 Slag and Cl2 Treatment
High Temperature Materials and Processes, 2012 In order to optimize a boron removal process by slag refining to obtain solar grade silicon, the rate of boron removal from molten silicon using CaO-SiO2 slag was investigated at 1823 K in an Ar atmosphere.

Evaluating Plasma Torches as a Low‐Decarburization Preheating Method for MgO–C Refractory Linings
steel research international, EarlyView.This study evaluates direct current (DC) plasma torches using nitrogen as an alternative preheating method for magnesia‐carbon (MgO–C) refractory‐lined ladles. Full‐scale trials at 0.7 and 1.5 MW are compared to conventional gas burner. Plasma‐heated samples show lower decarburization and improved surface integrity due to partial sintering and reduced ...
