1.Vacuum Heat Treatment 2.high hardness 3.Long service life 4.Vacuum gas quenching and minus 200°C degrees, cooling, tempering, to improve the hardness. ZTZG is strict quality control in raw materials, processing accuracy, heat treatment, assembly accuracy, standard parts, etc. The pass rate of equipment delivery is 100%.Tube Roller Process Raw material - sawing material - rough processing - Drilling - fine finishing - roller polishing - Typing Code - semi-finished product inspection - heat treatment - grinding hole - horizontal die cutting KEYWAY - quality inspection - oil cleaning - packaging Heat treatment way: There are four heat treatment way for your choose. (1) Vacuum Heat Treatment :HRC 61-63 (2) Black treatment: HRC61-63 (3) Nit riding treatment: HRC61-63 (4) Vacuum Gas Quenching and Subzero Heat Treatment:HRC63-65 Warm reminding: Tube diameter≥133mm, HRC:58-61 Different heat treatment way , different price!Tube Roller Packing: 1.Rust proof oil should be added to the export tube roller mould before removing the stains. 2.Packing in wooden boxes, lined with paper and cloth , to avoid bruising ,then use shockproof membrane. 3.The most outboard wooden packing , all the goods shipped by sea require fumigation wooden boxes.
