Introduction

SCHOOL

PRODUCTION of CLEAN STEEL

Mintek, Johannesburg

25-26 July 2016

South Africa has a proud history in the production of both mild steel and stainless steel with production facilities in Gauteng, Kwazulu-Natal, Mpumalanga, the Eastern and Western Cape provinces. At these facilities steel is produced from scrap or from ore via ironmaking facilities. The Center for Iron and Steelmaking Research at Carnegie Mellon University in Pittsburgh, Pennsylvania, USA has a proud history on iron and steelmaking. Collaboration between CMU and the South African iron and steel industry includes a school on steelmaking presented by Prof. Richard Fruehan in Vanderbijlpark in 1996.

About the Lecturer

About the Lecturer

Prof. C Pistorius

Chris Pistorius is the POSCO Professor of Iron and Steelmaking in the Department of Materials Science and Engineering at Carnegie Mellon University (Pittsburgh, PA, USA), where he has been since 2008. Previously he was Professor and Head of Department of Materials Science and Metallurgical Engineering at the University of Pretoria. He holds Bachelor’s and Master’s degrees in Metallurgical Engineering from the University of Pretoria, and a PhD from the University of Cambridge, United Kingdom. His current research interests include the fundamentals of iron making and steelmaking reactions, and electrochemistry of corrosion and metals production.

Topics

Topics

At Clean Steel 2016 Prof. Chris Pistorius will continue the collaboration by addressing the following topics:

CONTROLLING DISSOLVED ELEMENTS
1. What is clean steel?
2. Relevant process conditions in blast furnace, steelmaking converter, electric arc furnace, ladle furnace and caster (temperatures, oxygen activity, slag basicity, stirring).
3. Control of dissolved elements (C, H, N, O, P, S, Cu, Sn):
a. Sources (raw materials; environment)
b. Thermodynamic and kinetic principles of control
c. Practical control methods:
i. hot metal desulfurization and dephosphorization
ii.metal-slag reactions in blast furnace, steelmaking and ladle
iii. clean tapping
iv. metal-gas reactions, including nitrogen pick-up
v. deoxidation
vi. role of slag
vii. mitigating the surface quality effects of Cu & Sn.

CONTROLLING MICRO-INCLUSIONS
1. Principles of control:
a. inclusion composition evolution over time
b. removing inclusions to slag or fluxes: gas stirring and flotation kinetics
c. inclusion-metal-slag reactions: equilibria and kinetics (spinel formation)
d. calcium modification.
2. Sources of micro-inclusions:
a. deoxidation and reoxidation products
b. ladle glaze
c. inclusions in ferro-alloys and ferro-alloy reaction products
d. mold flux entrainment
e. reoxidation.
3. Assessing micro-inclusions:
a. overall steel composition
b. caster behaviour
c. microanalysis (polished sections; extracted inclusions)
d. other analytical approaches.
4. Summary: general guidelines for clean-steel practice; opportunities to learn more and share information.
