Through-process developments and caster enhancement at Corus Scunthorpe to supply bloom for rail and special profiles

Journal Article


Abstract


  • The program of developments undertaken at Corus Scunthorpe were reviewed to enhance quality of boom intended as feedback for rails and special profiles. The key elements of the program were minimizing hydrogen pickup through the process route by ensuring the use of dry scrap in steel making, avoiding the use of newly relined ladles, and using high grade scrap to ensure low residuals content. For caster enhancement, bloom slow cooling facilities were modeled, designed, and installed for secondary hydrogen removal required for rails and B-Ti steels. Steel making, casting practice, and process control were reviewed to achieve optimum quality and significant reductions in rejection rates were achieved to allow successful supply of products into new markets. Extensive quality control checks are made to ensure product quality before dispatch that include steel composition, hydrogen requirements, internal quality, production report, bloom dimensions, process parameters, and presentation.
