The combustion of pulverized coal in tuyere and raceway directly affects the production efficiency of smelting. Based on the design and production data of a 2000 m³ blast furnace, a three-dimensional mathematical model of pulverized coal combustion in tuyere and raceway is established. The lower part of the blast furnace consisting of blowpipe-coal lance-tuyere-raceway and coke bed is numerically simulated to study the influence of blast rate and oxygen on pulverized coal combustion under a certain coal injection ratio and a certain coal particle size distribution. The simulation results show that the pulverized coal burnout decreases from 69.2% to 67.4% when the blast velocity is increased by 20 m s⁻¹, and the oxygen content increases from 23% to 27%, which can improve the pulverized coal burnout and increase the temperature in the raceway. A new direction is proposed to increase the pulverized coal burnout by optimizing the particle size selection and increasing the injection ratio of small particle size below 50 μm.

He then took positions in the steel industry from 1979 till 2002. He first served at Vereinigte Deutsche Metallwerke as manager quality and research of the melt shop Unna. Since 1987 he headed the metallurgical department of Krupp Nirosta (later ThyssenKrupp Nirosta).&lt;/p&gt;&lt;p&gt;After habilitation In 1998 he became, in addition to his industrial activity, private lecturer (Privat-Dozent) at the RWTH Aachen for the topic Metallurgy and High Temperature Reaction Technique. In 2002, Piotr Scheller accepted the call for the Chair of Iron and Steel Metallurgy at TU Bergakademie Freiberg in Saxony. Until January 2012 he headed the Institute for Iron and Steel Technology which can look back on a long and important history. He also served as the dean of the Faculty for Materials Science and Materials Engineering, he initiated collaborations between the TU Freiberg and universities in Poland, China, South Korea, Sweden and Ukraine. In 2011 he received the »Medal of Honor« from the Academy for Mining and Metallurgy Krakow for his scientific achievements in Saxony-Polish cooperation. During his active time in Freiberg he built up a laboratory with the most modern experimental techniques for the measurements of surface tension and viscosities of molten phase at steelmaking temperatures along with numerous other experimental equipment. Since his retirement he has been invited as visiting professor by a number of famous universities in the world.&lt;/p&gt;&lt;p&gt;&lt;/p&gt;&lt;p&gt;His achievements in the scientific field are comprehensive and very diverse. Based on industrial experiments, Piotr Scheller described the flow behavior in the ladle and delivered important contributions to the kinetics of nitrogen transfer between gas and Cr-Ni-alloys. The precipitation of non-metallic inclusions especially in the continuous casting process was the starting point for the investigation of the interfacial phenomena between liquid steel and slag. In fact, his contributions in the area of interfacial phenomena and the application of the same in process metallurgy are extremely important in modelling various two phase reactions in metallurgical processes. Professor Scheller has been author of ca. 200 publications in reputed journals in the field of process metallurgy. His contributions to the book “Treatise on Process Metallurgy”, Elsevier publications, both as section editor as well as a contributor to several chapters, are highly significant. The 2nd edition of this book, scheduled early 2024, will see further contributions of him. He is owner of 6 patents/patent applications in the field if iron and steelmaking.&lt;/p&gt;&lt;p&gt;This special issue in steel research international is dedicated to Professor Scheller on the occasion of his 75th birthday in 2024.

In the investigation, elevated temperatures and the coarsening of metallic phases and carbides are revealed to contribute to the degradation of the steel's strength–toughness relationship. Utilizing computational thermodynamics, the stability of secondary phases, including carbides and brittle inclusions, is simulated to enable precise phase equilibrium calculations and accurate prediction of key mechanical properties such as yield strength, tensile strength, and hardness. These simulations facilitated targeted modifications to the alloy composition to enhance the steel's strength and hardenability under high-temperature, high-pressure conditions. In this study, alloy composition and processing parameters within the CALculation of PHAse Diagram framework, utilizing the ThermoCalc and JMatPro software packages, are optimized. In the microstructural investigations conducted under various isothermal deformation conditions (1173–1473 K) and strain rates (0.001–1 s⁻¹), it is demonstrated that DRX mechanisms led to varied grain size developments, with a critical strain rate identified at 0.01 s⁻¹ during high-temperature deformations.

It delves into the evolution of TiC precipitation and dynamic recrystallization (DRX), along with the austenite decomposition transformation during hot compression and subsequent cooling. Active dynamic recrystallization commences at deformation temperatures above 1050 °C, facilitated by the diminished pinning pressure of TiC carbides. This leads to the development of fine DRX austenite grains, influenced by an increase in strain rates and a decrease in temperature. Simultaneously, the fraction of TiC dispersions decreases as the deformation temperature increases, yet they maintain a consistent size of 5–10 nm. The refined particle size is attributed to their low interfacial energy with the austenite matrix, determined by the first principle to be 0.21 J m⁻². Due to the severe deformation and numerous dispersions, specimens subjected to a thermal deformation regime at 850 °C and a strain rate of 7 s⁻¹ present a peak in hardness, reaching a maximum of 324 HV.

The results demonstrate that the addition of Mo leads to the narrowing of the phase transformation interval of proeutectoid ferrite and pearlite, the expansion of the bainite transformation zone, a delayed bainite phase transformation process, and the refinement of bainite microstructure. Moreover, theoretical calculations of bainite phase transformation kinetics reveal that the average activation energy for bainite transformation in Mo-free and Mo-containing steels is 94.8 and 134.0 kJ mol⁻¹, respectively. The new grains of Mo-free steel mainly grow in a 2D mode, while Mo containing steel mainly grows in a 1D mode, which confirms the retarding effect of Mo on bainite grain growth. Additionally, Mo significantly increases the number density and refines the size of precipitated phases in weathering steel of bridge construction. Within the cooling rate range of 0.1–30 °C s⁻¹, the hardness of weathering steel of bridge construction is enhanced by Mo, with the magnitude of hardness increment decreasing as the cooling rate increases.

Flux is one of the key factors that determines the bonding degree of quasiparticles. Selecting high-quality flux is an effective way to improve both the permeability and thickness of the sintering bed. Herein, the hydration activity of quicklime flux is used as a criterion to assess quality. Two types of quicklimes with different activity levels are selected for comparative analysis in three aspects: microstructure, sinter quasiparticle granulation performance, and the sinter mineralization process. The experimental results show that active quicklime has a higher CaO content and fewer impurities. The small and dense CaO particles give active quicklime significant advantages in raw material granulation and sinter mineral formation. The application of active quicklime can effectively improve the permeability of the sintering bed; notably, the drying fines’ removal rate decreases from 22.81% to 2.42% with an increase in the ratio of active quicklime addition. However, this affects the average particle size of quasiparticles. To address this issue, solutions are determined by adjusting the condition parameters.
