Kinetics of Dephosphorization from Steelmaking Slag by …

It is well-known that the recycling of steelmaking slag in iron and steel industry would bring out a problem of phosphorus enrichment in hot metal, which will do harm to steelmaking process. In the present paper, dephosphorization from steelmaking slag by leaching with solution composed of citric acid, sodium hydroxide and hydrochloric acid was studied.

New Developments in LD Steelmaking | SpringerLink

A nuer of recent developments have widened the area of appliion of the LD, basic oxygen steelmaking process. These include ore cooling, production of high-carbon and low-alloy steels, and the utilization of high-phosphorous hot metal. This article describes how these techniques have been used in 12 LD steel plants.

Avoiding slopping in top-blown BOS vessels

Steelmaking (BOS) vessel, i.e. in the LD-process. Slopping reduces process yields and may lead to discharge of pollutants to the surrounding environment. This thesis presents a study of the basics of the slopping phenomena in a top-blown BOS vessel and an

Steelmaking - Wikipedia

Steelmaking has played a crucial role in the development of ancient, medieval, and modern technological societies. Early processes of steel making were made during the classical era in Ancient Iran, Ancient China, India, and Rome but the process of ancient steelmaking was lost in the West after the fall of the Western Roman Empire in the 5th century CE.

Linz-Donawitz converter

LD converter steelmaking is a complex physico-chemical process where many variables have effects on thequality of the resulted steel. The main features of the process are the followings: a large (~150-ton) converter is filled with waste iron, melted pig iron and many additives, then it is blasted through with pure oxygen to burn out the unwanted contamination (e.g. silicon, etc.).

The development and operation of an on-line digital computer for the LD basic oxygen steelmaking shop of Nippon Kokan’s Kawasaki works are described. The mathematical models—evolved for the computer on the basis of statistical analysis of operating data—and the rationale in their development are given in detail. Standard deviation results from six months of computer-controlled operation

[PDF] Chapter 9 Oxygen Steelmaking Processes | …

22/7/2020· The oxygen steelmaking process rapidly refines a charge of molten pig iron and aient scrap into steel of a desired carbon and temperature using high purity oxygen. Steel is made in discrete batches called heats. The furnace or converter is a barrel shaped, open topped, refractory lined vessel that can rotate on a horizontal trunnion axis. The basic operational steps of the process (BOF) are
