Quality Control

SRC maintains a very strict quality control system. In addition to the usual inspection process, such as profile check roundness, cylindericity, and etc, we check the following to ensure quality standards.

  1. Microstructure analysis : We analyze the microstructure of coating layer of every roll
  2. Wear resistance Test : On a regular basis, we do wear resistance tests of the tungsten coating layer.
  3. Crown and Paper Feeding Test : We evaluate the amount of crown and line-pressure in the test station where the steam is serviced. We also perform paper feeding test to check the runnablity of the rolls.
  4. Shock Resistance Test : On a regular basis we check the shock resistance of the coating, and try to make an improved our coating.
