Why does steelmaking need desulfurization
Why Desulfurization is Necessary for Steel Refining
Steel refining is a necessary process for producing various grades of steel for a variety of industrial and domestic applications. The process typically involves multiple stages to refine the steel until it meets the target specification. One of......
Low-alkalinity synthetic slag for external refining of molten steel
Low-Alkalinity Synthetic Slag for External Refining of Steel Melt
The quality of steel products relies heavily on the efficient removal of non-metallic impurities from the steel melt. Impurities, such as sulfur, phosphorus, oxygen and aluminum, are detrimental to the mechanical properties of the ......

Inert gas blowing technology in steelmaking
Abstract
This paper studies the development, application and principle of inert gas blowing technology in steelmaking, and reviews its effect on increasing the efficiency and environmental performance of steelmaking. It is believed that inert gas blowin......
Adoption of hot metal pre-desulfurization technology in steelmaking production
Introduction
The process of producing steel has changed since the introduction of the Bessemer converter in the 1850s. New technological advances have made it possible for steel to be produced quickly, with a high degree of precision, and with reduced environmental impact. The use of iron ores wi......
Judgment of carbon content in molten steel at the end point
Carbon Steel Heat Treatment and Final Product Carbon Analysis
1. Introduction
Steel manufacture and heat treatment processes are considered by many to be among the oldest and most dangerous industrial practices humanity has produced. As technology increases, so does our understanding of how this......
Converter foam slag
Ladle skim dross, also called ladle slag or ladle foam slag, is a typical dross generated during steelmaking process. It is also an important type of steelmaking slag.
Ladle skim dross is generated when the liquid steel is processed in the ladle refining and steelmaking furnace, especially when u......
End point temperature adjustment in converter steelmaking process
Temperature Control of Continuous Casting and Reheating Furnace in Steelmaking Process
Temperature control is an important factor in the steel-making process. It plays a key role in controlling the properties and characteristics of the produced steel. In continuous casting and reheating furnace, ......
Oxygen supply intensity in converter steelmaking process
In recent decades, the practice of oxygen enrichment in the process of steelmaking in open-hearth furnaces has developed in leaps and bounds. In particular, the utilization of oxygen to significantly reduce furnace fuel rates and increase furnace heat release are crucial. Therefore, understanding ......
Sequence and principle of alloy addition in converter steelmaking process
Alloy Addition Sequence in Steelmaking Process
Steelmaking is an energy-intensive process and the production of steel in converters requires a complex mix of raw materials, including iron ore, coke and limestone, as well as a variety of non-ferrous alloys. The correct sequence of addition of thes......
