FOllowing is material grade of
D3,1.2080, X210Cr12, SKD1
D2,1.2379,X153CrMo12, SKD11,DC53
H13,1.2344,X40CrMoV5-1,SKD61
AISI 52100,100Cr6 , EN31
FOllowing is melting methods for forging steel cold forming rolls
1 EAF: Electric Arc Furnace
2 EAF+LF+VD: Refined-smelting and vacuum degassing
3 EAF+ESR: Electro Slag Remelting
4 EAF+PESR: protective atmosphere Electro Slag Remelting
5 VIM+PESR: Vacuum induction melting
Our cold forming rolls is widely used in forming shape in following U-shape W-shape Z-shape steel sheet pile, color coil, section bar and so on
We could do forged, heat treatment, final machined cold forming rolls as per clients drawing
ALl our finished cold forming rolls should be accepted by the QC department of the manufacturer by conducting the following
examinations:
1) external examination;
2) a check of dimensions and marking;
3) chemical composition examination;
4) mechanical tests;
5) macrostructure examination;
6) residual stress measurement;
7) ultrasonic testing;
8) periscopic testing.
ALl our finished producrtion of cold forming rolls should have inspection certificate as per 3.1B of EN 10204 shall be provided to clients in triplicate;this certificate must contain the following dala:
(a)Material code no and P.O.number
(b)Material designation
(c)Heat no.,heat analysis and melting methods
(d)Table with the single results for determination pf the purity grade at microsections and value of purity grade K1
(e)Mechanical test results including hardness range
(f)Complete information on all heat treatments performed
(g)Results of NDT tests performed
(h)Confimation of material identification check
(i)Confirmation of dimensional and visual check
