Kvaerner Davy, which is installing a walking beam reheat furnace for the British Steel Scunthorpe Heavy Section Mill, subcontracted the plant's process control and electrics to Ansaldo UK. The system to be supplied is designed to work in either automatic or manual modes and interfaces with the Davy on-line modelling system for calculation of setpoints and furnace residence times. British Steel's Heavy Section Mill at Scunthorpe currently takes its feed stock from hot ingots which are re heated to rolling temperature in soaking pits. The soaking pits - which have been in operation for a number of years - now require refurbishing and their fuel efficiencies are below current day expectations. Operational changes are thus being made which will allow the mill feed stock to be taken from cold concast slabs. These changes require a new furnace arrangement to re-heat the slabs to the correct rolling temperature.
