[Case Study] Long-lasting seal rings and oil seals with explosive thermal spraying!

Long lifespan of seal rings and oil seals with explosive thermal spraying!

In the roll shop (the department that maintains rolls), tasks such as polishing rolls, maintaining seal parts, and servicing polishing machines are performed. Iron seal rings and rubber oil seals are used in the roll polishing machine's components, and both of these parts experience significant wear and have a short lifespan, leading to time-consuming and labor-intensive maintenance issues. Issues and Points: 1. The oil seals are inexpensive and can be replaced regularly, so we want to extend the lifespan of the seal rings. 2. Since the seal rings themselves are not very expensive, we would like to implement cost-effective measures. The inability to insulate these two areas leads to heat dissipation and losses. 3. Various tests have been conducted in the past, including hard chrome plating, carburizing treatment, and Dycron plating, but the results have not been satisfactory. (Both wear out in a short period, or one has a longer lifespan while the other has a shorter lifespan, etc.)
