Production of High-Quality Wheel Steel. Part 1. Production Aspects of Continuously-Cast Billet Quality for Railway Wheel Manufacture

摘要

Main parameters of secondary refinement and continuous casting for 400 mm wheel steel billets of grade 2 (GOST 10791-2011) manufactured by AO TAGMET are determined that provide the minimum nonmetallic inclusion content and absence of steelmaking defects detected with railway wheel ultrasonic monitoring. Additional monitoring procedures for continuously cast billet quality control are described in order to provide steel chemical composition homogeneity over a billet cross section and to minimize central porosity.
