Course Modules

The course consists of three modules which should be taken in sequence in order to complete the full course.

Module 1 – Charge Balancing and Slag Development

Content includes:

Charge balancing is an iterative process which is crucial for controlling analysis and timing of steel production
It is based on constantly changing information and has to contend with and take account of many uncertainties and inaccuracies
Slag is the primary system for removal of impurities
Development of a good slag is dependent on accurate information, accuracy of weighing and good process control

Module 2 – Blowing Control, Sampling and End-point Projection

Content includes:

Blowing control depends heavily on bath conditions
Lance height needs to be balanced between “hard” and “soft” blowing
Lance design aims to deliver supersonic oxygen to the bath in the shape of coherent jets
Lance height is the key control parameter
Systems are in place to minimise slopping
In blow sampling techniques can help with end point target performance
Dynamic adjustment is possible even at 85% of the blow
End blow computer models are used to hit the final aims

Module 3 – Bath Conditioning and Process Automation

Content includes:

Charge balancing will provide the right ingredients for a good slag, process control will provide the conditions for good slag formation but the nature and form of the slag is also important if the slag is to be effective in refining
The Bath Agitation Process can be used to improve slag conditioning and control slopping events
Systems exist to build on advisory systems and make some steps automatic
Performance is much improved through automation

What the course covers

The course covers the process control requirements for managing the primary basic oxygen steelmaking process to ensure good refining. The course will discuss the information and controls required to ensure steel is made by the BOS process in specification, within the timescales required for downstream processing.

Main topics covered are charge balancing, slag development, lance height control, prevention of slopping, blow endpoint control using inblow sampling and moves towards process automation

Learning Outcomes

The learning objectives are:

To understand how the BOS converter is controlled during steelmaking to obtain the desired end goal
To highlight how good process control is the key to consistency of operation
To understand the importance of accurate information on process control performance

Who should access the course?

Practitioners in the steel industry, such as scientists, researchers, technologists, technology managers and operations and operational management. Those who are, or who aspire to be senior leaders within the steel industry or academia.

Course Duration

3 x 40 minute modules
