AI Technical Summary

Technical Problem

Existing casting equipment suffers from molten metal cold shut-off due to temperature differences during the casting process, affecting the integrity and mechanical properties of the castings and leading to a decline in casting quality.

Method used

The system employs an adjustment and movement component in conjunction with a heating conduit. By adjusting the movement of the toothed plate and fan blades, the pouring channel is heated evenly. Combined with a heat transfer component, this accelerates heat transfer and prevents cold shut-off.

Benefits of technology

It effectively maintains the temperature of the molten metal in the pouring channel, reduces cold shuts, improves the integrity and mechanical properties of the casting, and enhances the performance of the casting.
