Pinch roller: at the end of the hot rolling production line, it is divided into an upper pinch roll and a lower pinch roll, and a pressure is formed between the two rolls to live in the steel and send it to the next machine
How the pinch roller fails:
Under the working conditions of high speed, high temperature and high pressure, due to the combined action of severe wear, it is easy to cause wear, block drop, weld bead lines, cracks, etc., which lead to its failure.
According to its failure mode, TecMig produce high hardness HRC55 or so resistant to deformation at high temperature, with impact resistance, good toughness, non-stick steel, wear-resistant welding wire. Greatly increases the service life of the pinch rollers
