AI Technical Summary

Technical Problem

In existing technologies, the temperature of the riser in the robot forearm casting drops rapidly under the impact of high-temperature molten metal, resulting in poor casting quality. Traditional heat preservation methods are ineffective and structurally unstable.

Method used

The thermal insulation sleeve adopts a composite layered structure, including a chromium-nickel alloy contact working layer, a ceramic fiber main insulation layer, a polyurethane foam thermal insulation buffer layer, and a stainless steel outer protective layer. It optimizes thermal insulation performance through mechanical protection, buffering thermal insulation, and thermal insulation functions.

Benefits of technology

It improves the heat preservation effect, ensures the temperature stability of castings, prevents the molten metal from cooling too quickly, improves casting quality and production efficiency, and extends the service life of molds.
