Steel Mill Process Heating Technology Study. Final Report, June 1994-February1995

摘要

The reheating of slabs, blooms and billets for hot rolling, and the annealing andgalvanizing of steel strip are historically large consumers of natural gas. However recent technology developments and steel industry trends toward near net shape casting and direct linking of the caster and hot rolling mill, have changed the role of reheat furnaces from one of reheating cold slabs, blooms and billets to that of a medium of transfer between the caster and hot mill, allowing mainly for temperature equalization. The study provides an evaluation of the suitability of technologies currently under development for application in these two process areas and suggestions for a commercialization strategy, by identifying potential competitors and barriers to market penetration.
