The I.S.P. technology, short production line for hot strips and plates*
Le procédé ISP de production directe de produits plats minces
The In-line Strip Production (I.S.P.) technology, developed and implemented jointly by Mannesmann Demag and Arvedi, is based on thin slab casting with cast-rolling of liquid and solid core, developed by Mannesmann Demag Hüttentechnik (MDH).
The new technology has been realized and applied in the first minimill for the production of 0.5 million tpy of quality hot strip 0.3 million tpy of structural steel and 0.2 million tpy of stainless steel grades, built by Arvedi.
This first steel mill built for high-quality hot strips based on an electric arc furnace with a capacity of 100 t for the production of finished hot strip was to go into production in Cremona, Italy, in December 1991.
This paper will report on, point out and describe the activities in the area of :
thin slab casting with and without cast-rolling with liquid core, during solidification in the 2-phase area, the mushy zone, its structure and material properties also after being rolled to flat products on production and research level,
the I.S.P. process line and its special features in processing and equipment, energy consumption and balance, enthalpy distribution, entropy generation with special reflection on the CO/CO2 and SO2 emission in comparison with other strip production lines with the final conclusion and outlook.
