Abstract

The grade 590MPa high strength steel for construction machine and mine machine can be produced in mass and at lower cost with optimization of chemical composition and production process. The thickness of steel plates is from 6 mm to 60 mm. The microalloy system can be designed as Nb-V,Nb-Ti or Nb-Ti-V. Due to application of controlled rolling and controlled cooling (thermal mechanical control process TMCP) the properties of steel plates are perfect. Test and process simulation be conducted in lab rolling mill. The results and process were transplanted to middle plate mill and heavy plate mill, the process parameter can be matched well and appropriately, the production process is smooth and properties of steel plates are excellent and stable. The new manufacture technology for production of 590MPa high strength steels is opened up. The output of 590MPa high strength steels has been reached more than 81000 tons every year in Jinan Iron and Steel Co. Ltd. and it meet the needs of market preferably. The application of this type high strength steel can create a great of economy and social profits.
