Forged Steel Rolls for cast shell Reversible-type water-cooled casting and rolling core

CASTING SHELL & CORE

Material

42CrMo, ladle refining melting

Structure:

Reversible-type, water-cooled casting & rolling core structure,

which is with high cooling capacity, makes even temperature

on the roll surface, and ensures product in good shape.

Manufacturing Process of Sino steel Roller Core

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