Engineering: M2A Fully Funded EngD Scholarship: Effects of residual elements from scraps on steel processing and service properties of typical strip steel products

Closing date: 28 February 2018

Key Information

Start Date: October 2018

Sponsoring Company: Tata Steel

Academic Supervisor: Dr Zushu Li (University of Warwick / Swansea University)

Significantly increasing the use of steel scrap in steel production has become a strategic movement for the UK steel industry (including Tata Steel UK). This is driven by the EU/UK government compulsory target of reducing emissions by 80% before 2050 for industry and is motivated by the current over-supply of steel scrap and its projected growth in quantity into the 2020’s.

The biggest challenge for the increased use of steel scrap is the residual elements (e.g. Cu, Sn, Zn, Co) inherited from the steel scraps that influence the steel processing and service properties of steel products. The most problematic scrap is obsolete scrap, consisting of discarded steel products after their service life (e.g. passenger cars, steel cans, electric appliances) and municipal incinerator scrap. Its chemical composition fluctuates widely depending on its origin and degree of processing.

The residual elements can influence the processing conditions of steel, from ladle treatment through casting and thermal treatment (e.g. annealing) to coating, and may exist in steel in the forms of solid solution, precipitation, intergranular segregation and surface segregation. All these directly and indirectly affect the quality and service properties of steel products.

This project aims to advance the understanding of the effects of residual elements on steel processing and service properties, and consequently create optimized through-process parameters for effectively controlling the effects of residual elements, i.e. substantially increasing the use of high residual scraps without sacrificing the steel processing performance and service properties.

The work will be carried out by using the world leading research facilities (at up to 10 kg scale) at the Advanced Steel Research Centre in WMG, the University of Warwick and at Swansea University. The proposed research will simulate the steel manufacturing process in laboratory from melting (with intentionally added residual elements), casting, hot rolling, annealing, to coating, aided by property measurement and advanced characterisation. It will reveal the link between the amount of residual elements (individual and or combined) and the steel processing performance and the properties for the selected key strip steel products.

Project Aims:

  1. Critical assessment of the state-of-art of the residual element effects on steel processing and service properties.
  2. To investigate in laboratory the effect of residual elements (individual and combined) on processing – hot rolling, hot shortness, surface quality, etc., for the selected key products.
  3. To investigate the effect of residual elements (individual and combined) on properties (strength, ductility) of end products for the selected key products.
  4. To recommend through-process parameters for the substantially increased use of high residual scraps without sacrificing service properties of steel products.
