Cemented carbide composite roll Application

The cemented carbide composite roll is mainly used on the finishing mill for bar, deformed steel bar and common wire.

ln accordance with the production line and rolling technology of customers, our products aredesigned to match one-strand rolling, two-slitting rolling and three-slitting rolling. three-slittingrolling.,andfourslittingrolling.,The cemented carbide composite roll includes K1 finished roller,K2 lederroller,K4pre-slitting roller.K3 slitting roller with high-speed steel as material.The rolling varietiesinclude wire,bar and deformed steel bar.

Advantages of cemented carnide composite roll:

We can greatly reduce the frequency of changing groove and roll, thus to reduce the labor intensity and improve the work efficiency.Thesurface quality and yield shall be improved to a maximurm degree, which leads to a remarkable economic benefit.

Our cemented carbide composite roll adopts a special grade of cemented carbide. By means of hydraulic lock nut, the cemented carbide rol rings is fastened to the axle with the axial pressure of 2O0O Mpa from hydraulic oil.Under the protection of prestress, thecemented carbide composite roll shall work more effectively.

We can effectively reduce the frequency of changing rollers and increase the yield after usingcemented carbide composite roll. The rolling products possess the features of good surface quality,small deformation, negative tolerance and high yield.

Cemented carbide roll Production Process

Product design→ Roll blank design→ Roll blank manufacturing→ Roll blank acceptance→ Annealing→ Rough turning→ Ultrasonic flaw detection→ High temperature quenching→ Low temperature tempering→ Ultrasonic flaw detection→ Finishing→ Ultrasonic flaw detection→ Roll body grinding→ Roll numbering→ Inspection→ Cleaning → Packing → Shipping → Warehousing → Inspection → Use and Maintenance → On-site Communication → Design Improvement.

As can be seen from the flow chart, roll manufacturing forms a closed-loop system from product design, production and manufacturing, use and maintenance, and improved design, and the quality of rolls is constantly improving.

cemented carbide roll testing standards

Design specifications and standards for manufacturing, quality control and inspection

The relevant standards of the roller ring are as follows:

  • Anti-rust packaging implements GB/T1504 and GB/T1503-2008 standards.
  • Sampling method of samples for chemical analysis of GB222 steel and allowable deviation of chemical composition of finished products
  • GB223 Chemical Analysis Methods of Steel and Alloy
  • GB/T13313 Roller Shore Hardness Test Method
  • GB/T1804 General Tolerances Tolerances of linear and angular dimensions without tolerances
  • GB/T1503-2008 National Standard for Cast Steel Rolls

    Testing regulations:

  1. Check the size and surface quality of each part one by one;
  2. Carry out ultrasonic flaw detection three times one by one;
  3. Carry out hardness test piece by piece;
  4. The depth of the hardened layer of the roll body is affected by the manufacturing process.

Although the price of LMMGROUP is 1.22 times that of the current rolling stock, through this trial, the data shows that the amount of steel passing through is more than 1.3 times higher than the current rolling stock, and the rolling groove wear of the off-line rolling is better than the current rolling stock.
@Steel B
Read More
According to the trial situation, The average amount of steel passing through LMMGROUP rolling is about 50%-60% of the alloy rolling spoke. The processing difficulty of high-speed steel is low, and the processing cost is lower than that of the alloy rolling wheel.
