TECHNOLOGY
VC + ESR
VC casting is carried out under vacuum in a vacuum degassing unit.
- Dissolved Hydrogen is controlled to 1.0-1.5 ppm.
- To minimise gas pickup (oxygen and hydrogen).
- Clean ingot.
- Homogeneous and refining microstructure.
- ESR roll has the advantages of high wear-resistance, high anti-accident and high uniformity of surface hardness.
- We TSR rolls, Only provide ESR roll for customers.
FORGING
- Typical forging reductions for work rolls is 3:1, to avoild the loose structure defect,optimize the microstructure.
- Forged Rod Blanks Standard GB/T15547-2012.
QUENCHING AND MACHINE
- Automatic control induction heating power, stable quenching heating temperature.
- Quenching by Constant temperature cooling water, steady quenching cooling intensity.
- Multi-heating induction rings design to ensure the heating depth and meet the customer 's Working Layer requirements.
TSR Roll has a machining shop of more than 15.000 square meters, including the lathe, boring machine, grinding machine and other modern processing equipment for rolls. Thanks for the first-class operator working on high-precision CNC equipment, it is easy to produce the rolls with various kinds of grooves and precise tolerances.
- CK61160 CNC Lathe, Maximum capacity: 32T
- MK84200 CNC Grinding machine, Maximum capacity: 50T
- C9125*6/63 Turing and Boring machine, Maximum capacity: 63T
- T6920D Boring machine
