Advanced Technology to Anneal Current and Future AHSS
Water Quench technology has been used on certain continuous annealing lines for more than 30 years now to produce HSS grades and the market tendency for higher strength steel grades is accelerating today.Various AHSS grades have been developed for which yield strength and other properties are also considered,to ensure formability.The production of AHSS grades in a continuous annealing line requires a strict cooling control to limit strength deviation within the coil to improve homogeneity and formability.To reach the required AHSS characteristics,Wet Flash Cooling? has been developed,offering a more flexible control of the strip cooling cycle,including initial and final strip temperatures and modulation of cooling rate.This technology has been successfully operating in a large capacity industrial continuous annealing line at a major steel plant for 6 years following its start up in 2009.This paper describes the new challenges of quenching technologies to respond to the evolving AHSS production needs.
