Show jumper by night and materials engineer by day, Danielle Burrows straddles both areas comfortably. The engineer at BAE Systems’ site in Blackburn, UK, chats to Rupal Mehta about how her unflappable attitude towards new challenges and pressures has helped her settle into her job with no previous materials background.
Introducing glazing materials after secondary metallurgy could reduce the environmental impact of ladle furnace (LF) slag, a by-product of steelmaking.
The technique is designed
to make the slag easier to
handle while reducing powder dispersion.
The UK economy is said to have clawed its way out of its deepest recession since the 1930s, but are we out of the woods yet? Gary Price talks to representatives from various technical communities about the difficult financial year that has passed and what may lie ahead.
A UK consortium is modelling how trisiloxane surfactants ‘superspread’ across hydrophobic surfaces at the nanoscale. The aim is to develop guidelines for synthesising safer surfactants and provide advice on how to control the stages of spreading to suit a particular application
Real-time monitoring of high-density polyethylene (HDPE) production is now possible, claim researchers in Germany. Their technique uses a combination of laser reflectance measurements and video monitoring to follow ethylene polymerisation in stirred slurries under different conditions.
A novel bi-component fibre using two different polymers may pave the way for a concrete that has the required impact resistance and flexural strength but without the need for steel fibre reinforcement. The technology is said to overcome the previous challenges of producing high performance concrete using polymeric fibres.
Improving the oxidation resistance of carbon-containing refractory bricks and the wettability of castables is the focus of research at the University of Sheffield, UK. This could enhance furnace lining life and performance to benefit the metallurgical processing industries.
Pilot trials are ongoing to remove iron and sulphate, using a bioprocess, from the acidic effluent that results from heap bioleaching metals from minerals. The work is being undertaken at the Talvivaara Mining Company’s nickel mine in Sotkamo, Finland. The technique is said to be more cost effective and environmentally friendly than current methods for iron removal.
