STEEL - TECHNOLOGY TRANSFER
Cladding Continuous Casting Rolls

Continuous casting rolls are subjected to very harsh environments including high temperature oxidation, corrosion, stress corrosion cracking, thermal fatigue, abrasion and adhesion. The interaction between the slab and the continuous casting roll surfaces is highly complicated as multiple failure mechanisms tend to operate simultaneously. The rolls often show premature corrosion marks due to inadequate welding materials or improper welding technologies.  The service life can also be less than satisfactory if the roll surfaces wear out and the required roll gap is no longer maintained. Kladex delivers improved service life of the continuous casting rolls by:

 

  • Understanding the service conditions

  • Determining the failure mechanisms

  • Selecting the most suitable alloys

  • Understanding the relationship between the welding processes and the microstructure evolution

 

Kladex has the expertise and knowledge in the materials' science welding metallurgy and the welding automation to bring the most effective solutions to its customers.

Hardfaced Plate Manufacturing

 

 

Hardfaced plates are widely used in applications to improve the service life of the components against abrasion, impact, erosion and sometimes a combination of those mechanisms at elevated temperatures or in corrosive environments. They are commonly produced in the form of large plates and later cut and shaped to suit applications. The industry adopts various alloys ranging from chromium carbides to complex tool steel alloys with primary carbides. Kladex has the knowledge in offering:

 

  • The most suitable alloy selection

  • Design and delivery of automation

  • Welding engineering and operator training
