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.
