Improved steelmaking productivity by achieving operational stability
Stability is everything in steelmaking operations and the fundamental criteria for successful steel production management. Without stability, everything will suffer, bringing your production performance, safety, and product quality down – and vice versa.
Digitalisation in steelmaking embracing industry 4.0
The industrial digitalisation revolution transforms the steel industry by forming new ways of working, more some than others. Understanding industrial digitalisation and the opportunities that arise is vital for building
success. Ensure you understand what path you (and your competitors) are likely to follow in the coming years and remember to stay ahead before you fall behind.
Steel production management system – a strategic asset
A production management systems is a strategic asset in the competitive world of steel production. Operations level automation hosts critical company know-how that enables recent developments in digitalisation and artificial intelligence. Do not get left behind.
Efficient scrap usage in Outokumpu Avesta Works
In this paper the use of internally generated stainless steel scrap is discussed. Internal scrap usage and internal scrap substitution with purchased alloys or purchased scrap is examined in the industrially proven UTCAS® converter automation system.
Value creation in simulated steel
In this paper it is highlighted how the simulated steel making process generates value and it is discussed how this value can be measured. Special applications in process development, training and investment evaluation are presented and practical examples are used to illustrate how value is created.
Refining in AOD at high productivity with low environmental impact
By implementing a converter downstream of the reduction furnace it is possible to broaden the product range significantly. In this paper some process alternatives and their economical, practical and environmental implications are studied using process models developed based on UHT’s long experience in stainless steelmaking, stainless steel process control and charge chrome refining.
Optimizing the environmental footprint and production costs in stainless steel refining
In this paper the UTCAS® process control solution for AOD converter refining is presented briefly and its ability to optimize business while considering environment is high-lighted. The value and benefits to the steelmaker and the environment are illustrated by practical examples from simulated cases.
Ferroalloy design selection, utilization and optimization
In this paper different FeNi and FeCr compositions are discussed and their merits for stainless steelmakers in different situations are compared.
Control and optimization of material additions throughout the AOD refining cycle
In this paper, the real time AOD process control system UTCAS is presented briefly with a focus on its ability to control and optimize cold material additions throughout the AOD refining cycle. In order to emphasise the benefits of this ability, different scenarios are discussed and evaluated.
The complete system for converter process management
The UHT Converter Automation System, UTCAS®, is a highly sophisticated computer system especially designed and developed for converter refining processes. The UTCAS® concept combines effective real-time process control system with advanced tools for process design and production evaluation, thereby providing the complete solution for converter process management.
