Manufacturing Process of Sino steel Roller Core
- Forging: 12000T hydraulic presser with forging ration not less than 3
- Heat treatment after forging: normalizing + tempering, relieving forging stress
- Rough machining: machining subject to dimension requirement of hardening and tempering treatment
- Detection: according to GB/T6402-91 with accuracy of Class 2
- Hardening and tempering treatment: hardness 300-340, furnace cooling for stress relieving
- Sample cutting: mechanical property inspection
- Full body welded with stainless steel by machine
- Surface rough turning after welding
- Surface heat treatment hardness: HRC40
- Detection to inspect no defects on the surface, such as cracks etc.
- Semi-finish machining: drilling axial and radial water holes and making radial water groove
- Stability treatment
- Finish machining: finish machining each dimensions to meet the dimension requirements in the drawing except for outer diameter and roll neck
- Final finish machining: finish grinding outer diameter and roll neck to meet the dimension requirements in the drawing
