LOI is now to supply line #2 and line #3 for the LOI heavy-plate heat treatment facility at Baoshan Iron and Steel, China, which has been operated successfully since the beginning of 2005.
The scope of supplies includes one roller hearth furnace for normalizing, and another roller hearth furnace for tempering. The furnaces will be used to heat treat alloyed carbon steel and high-alloy steel plates. The plates, with thicknesses ranging from 5 to 200 mm, widths from 900 to 4,800 mm and lengths from 3,000 to 26,000 mm, are needed by the construction industry and for ship-building and boiler-making. In the radiant tube heated furnace line #2, the plates will be normalized in a protective controlled. In the open fired furnace line #3 they can be tempered by lowest temperatures with highest temperature precise. Depending on the type of heat treatment used, the capacity of each furnace line is up to 64 t/h.
The LOI plant, including the heating systems, will be highly automated and the control system is to feature a material tracking program. An optimization computer will adapt the furnace to the various load conditions, minimizing energy consumption, environmental impact, and ensure lowest scale formation for highest surface qualities.
The new furnace lines, which are the second expansion stage of the plant, are to be commissioned at the beginning of 2007.
