High temperature flame is used to heat the surface of the elevator quide rail. then spray water to cool the hot part of the guide rail, high temperature flame and water spray device move synchronously in the longitudinal direction of the elevator guide rail, realizing the moving quenching treatment of the entire guide rail surface, and finally tempering treatment, forming a hard quenching layer on the surface of the elevator guide rail. The wear resistance of the guide rails is increased to avoid vibration, noise and other unsafe factors caused by wear and tear.

To meet the operational requirements of high-speed elevators, MODUN Elevator invented a higher hardness more wear-resistant passenger elevator traction wheel. The wheel body is made of Q235 carbon structural steel with a semicircular groove. It is pressed by a hard quenched steel ball and coated with 2: 1 kerosene and borax powder. Finally a boronized layer is formed by electric contact heating at 400-500 C to achieve the best hardness and wear resistance.

MODUN express elevator independently developed a passenger elevator guide wheel, by improving the structure of the wheel itself to reduce friction resistance, quenching burner spray, cooling water spray at the same time, and rotating guide wheel, easy to adjust the speed of quenching temperature will be controlled at 900~950, so that the guide wheel not only has less friction resistance, but also hardness High wear resistance and great service life.
