B.Manufacture:

Continuous cast steel billets.

Flame Cut - Billet ends to be cut perpendicular to the longitudinal axis and to de-burr.

 

C.Surface Quality :

Should be free from harmful surface defects like surface crack (longer than 20 MM & deeper than 0.5 MM ); slag patches, scabs, pinholes, deep oscillation marks (deeper than 0.6 MM ).

 

 

D. Internal Quality :

Billets should be free from injurious internal defects that are harmful for the end products or for the rolling.

 

 

E. Marking :

Cast Number is to be punched/handwritten at the cut face of each billet

 

F. Bend :

Billet should be free from bend up to 400 mm length at both shear ends. For rest of length 30 mm /6 meter bend is acceptable.

 

G. Mill test certificate:

Should mention detailed chemical composition of each heats including tramp Elements, Nitrogen content & CE.

 

H. Packing list:

should include the number of billets in each heat supplied and the tonnage of each heats.

 

I. Colour code:

Billet grade should be identified with colour code; one grade should not possess more than one colour code. Similar grade billet supplied in different length and size should be identified with different colour codes or marks.
