DELIVERY CONDITION:
Billets and slabs are delivered as cast condition.

As cast conditions mean the cooling after casting. The following cooling procedures are used:

  • Cooling in pile
  • Cooling in retaining boxes to room temperature
  • Cooling in retaining boxes to 300C and then in air


SURFACE QUALITY:
As-cast products with the market of powder and scale as result of casting process. Facesurface after cutting with flame - cutting burner (some partial melting on the products surfacecan be visible), material flash is not removed. Visual control of CC products surface is madeonly. Maximum permissible depth of surface defects is 3 mm. The surface conditioning forproducts up to 2200 mm length only.

INTERNAL QUALITY:
Internal quality of continuously cast products is examined on as-cast transverse sectionscut from billets or slabs. All cuts slices are macro etched and estimated on accordance withASTM E381. Acceptable degree-patterns: C3-R3-S3. Macro etch sampling is agreed withthe customer. Bauman’s print as requested by the customer.

MARKING:

Billets of 1400 – 2200 in length are marked on face surface with marking device. Making includes: hear No; grade of steel; secondary metallurgy treatment code; strand No; product No. Additionally, CC product are marked with white paint (on face surface) – paint marking includes: Heat No; steel grade.
