The China Approach to Ring-die Manufacturing--Ring-die
[Brief Introduction]
Ring-die is divided into two kinds according to the raw material type: one is Stainless Steel Ring-die [X46Cr13 / INOX (4Cr13)], the other is Alloy-Steel Ring-die [20CrNiMo (SAE-8620) or 20CrMnTi (20MnCr5)]；
As per the fixing mode, it is divided into ring die with clamp fixture and ring die with bolts fixtures.
[Technical Specification]
Stainless Steel Ring-die: Material Type:X46Cr13 / INOX (4Cr13); Hardness: HRC55 -58 (For wood pellet mill); HRC52 -55 (For feed pellet mill); Heat treatment by Vacuum Furnace;
Alloy-Steel Ring-die: Material Type: 20CrNiMo(SAE-8620) or 20CrMnTi(20MnCr5); Hardness: HRC60 -62(For wood pellet mill); HRC58-60(For feed pellet mill); Heat treatment by pit-type cementation furnace (Cementation Depth: 1.0-1.5mm: 12-14 hours, Cementation Depth: 1.8-2.0mm: 24 hours);
[Chemical Specification]
