Definitions

  • the mechanical characteristics of the sheet thus coated closely correspond to those of mild steel sheet.
  • the qualities of the lead sheets obtained depend on the one hand on the basic mild steel sheet and on the other hand, on the lead coating then applied.
  • the manufacture of mild steel lead-dip sheets is carried out by using two successive techniques relating, on the one hand, to the base sheet and, on the other hand, to the coating of lead, that is to say -first of all to say manufacture of mild steel sheets having suitable mechanical properties and roughness according to conventional operating methods of mild steel, comprising in particular a cold rolling of coils previously hot rolled and pickled, an annealing of continuous or closed recrystallization, a rolling with a very small reduction in section carried out on a train called "Skin Pass" which aims, on the one hand to eliminate the bearing of elastic limit and on the other hand, to confer on the surface of the sheet the desired roughness state, the mild steel sheet thus obtained is then treated on a specific dip-sealing line proper.
