Reduced Slit Rolling Power in Rebar Steel

Namibia Gets Ready to Become the World’s

  • How is rebar steel produced?
  • Rebar steel is produced in hot rolling mills using grooved rolls [1]. It is the largest part of long rolled products and has high demand due to its application in reinforced concrete structures. Rolling is the most common bulk deformation process for rebar steel production.
  • Is Rebar mill scale a passive film?
  • The mill scale of rebar is not a passive film. It is a thick oxide layer formed by the oxidation of rebar during high-temperature rolling. Before discussing the passivation of hot-rolled rebars, it is necessary to give a description about the mill scale in details first. Figure 4.1 is the phase diagram of Fe–O system .
  • Should rebar steel production be revised?
  • The rolling process of rebar steel production is one of the well established manufacturing processes. However, it should be subjected to revision and redesign for productivity enhancement and power reduction throughout the slit rolling process.
  • How much steel rebar is produced in India?
  • For instance, India produced 50% of their steel rebars from scrap steel . Similarly, around 80,000 tons/year of steel scrap is being utilized in Gana . It is necessary to have quality control protocols for the used steel scrap to improve steel’s mechanical properties.
