Furnace specialist Seco/Warwick Allied recently installed seven soaking pit furnaces for Hindalco in Hirakud, Eastern India.
The furnaces feature side-mounted fans (for improved maintenance access) and a combination of fan and heater arrangements to produce separate control zones along the vertical length of the slabs. There is also a patented adjustable baffle design.
Each furnace can handle 128kt at maximum load. The overall charge height is 5 metres maximum and 3.5 metres minimum from eight to 16 slabs per batch, says the company.
The furnaces, which are designed for vertical loaded slabs to process can body stock, are designed for electrical heating and feature an individual self-propelled lid (or cover) mechanism. They are also equipped with a PLC-based control and monitoring system.
