                      Cold Rolling Mill Rolls

Among all the rolling mill rolls ,Cold rolling mill rolls requires the highest quality requirement,Its manufacturing technique is also the most complex ,Work roll for cold rolling mills work under extremely high rolling pressure to produce a plastic deformation upon the cold-rolled steel strips,
Besides, as a driving roller cold rolling mill roll have to bear the transmission torque. So its hardness and strength must be high enough.
 
TongYu has set strict inspection systerm in the cold rolling mill rolls production line, which is comprised of smelting ,forging ,heat treatment,flaw detection ,and machining ,The work rolls we produce are in line with the GB/T13314-2008 manufacturing standards.
 
Clients are required to offer their drawings and technical requirement, Which will transferred to technical department(heat treatment center, large forgings research center, mechanical research center, and welding department, etc,) for confirmaion and accounting, Then we will offer you the quotation, The ordered products will be put into production as soon as possible after clients have placed an order.  For any problems rasied in the product line ,We will contact and disscuss with our clients directly.
 
Material:
High-carbon steel, hyper-eutectiod steel, Chromium-molybdenum alloy,and forged steel , like 9CrMo and 9Cr3Mo
 
Manufacturing process
Smelting-Forging-Heat treatment-Rouging-Quenching and Tempering-Finishing-Packaging.

 

Back up Rolls

Backup roll is generally large size and heavy weight ,It is hard to manufactured .Back-up roll is used to support the work rolls by reducing the diameter of work roll and enhancing its rigidness,It helps to reduce the deformatino of work roll thus enhancing the plate precision and quality , With the rolls surface contacting with work rolls for a long service time ,back-up rolls must bear large contact stress and shear stress, the 2 forces of which will cause back-up roll to get deformed or worn.
 
Back-up roll works to undertake rolling pressure ,so it must be competent in strength,heat resistance and abrasion resistance .Our production line for rolling mill rolls mainly includes smelting, forging,heat treatment ,flaw detection ,and machining. The rolls are manufactured in accordance with JB/T6401-1992 larged forged rolls standards.
 
Clients are required to offer their drawings and technical requirement, Which will transferred to technical department(heat treatment center, large forgings research center, mechanical research center, and welding department, etc,) for confirmaion and accounting, Then we will offer you the quotation, The ordered products will be put into production as soon as possible after clients have placed an order.  For any problems rasied in the product line ,We will contact and disscuss with our clients directly
 
Common Material
Cr3 ,Cr5
 
Manufacturing process
Smelting-Forging-Heat treatment- roughing-Prelimilary heat treatment-Final treatment Finishing-Packaging.
 
Quality control
  1. Apart from the requried chemical elements ,we have strictly tested some harmful elements such as P S Pb Sn As Sb and Bi,as well as some gas or non-metallic debris like N H O in the smelting process.
  2. Strict forging technique is required to meet non-destrcutive testing requirements, The forged blanks will be given normalizing and spheriodizing treatment to refine the grains and remove the network carbides, and get a spherical pearlite strcture.
  3. Prelimilary and surface heat treatment is conducted on material to achieve great comprehensive mechanical properties, and high toughness of back-up rolls.
  4. CNC eqiupment is adopted for high processing accuracy
 
 
Features of Back-up rolls
  1. Back-up rolls made by Tongyu are of high comprewhensive strength and rigidness to bear the large rolling force and the peak load.
  2. With good toughness ,the back-up rolls wont go broken or cracked easily.
  3. The back-up rolls features good wear resistance and fatigue resistance.
  4. It is designed with uniform structure and hardness.
