Key Technology to Reduce Residual Stress Level of High Strength Steel

Abstract:

Given that the traditional hot temper passing process cannot fulfill the demand of high strength steel on residual stress level and stable processability, leveler and temper passing process with dual servo valve (LTP-DSV) is developed to solve this technical problem. LTP-DSV process employs leveler to reduce residual stress level of high strength steel; uses dual servo valve variable gain rolling force control technology to improve performance stability of high strength steel; improves surface quality of high strength steel by means of temper passing. The residual stress level of products is substantially reduced on condition that the performance of high strength steel is ensured. The actual production data shows LTP-DS process is able to improve the performance and quality of high strength steel from all aspects.
