AI Technical Summary

Technical Problem

Existing quenching furnace conveying devices suffer from heat waste, large heat loss, decreased furnace temperature stability, and low efficiency. In particular, when the pallet and railcar are integrated, the next batch of parts cannot be processed until the quenching is completed.

Method used

The feeding rack design, which uses an upper guide rail section and a lower guide rail section, enables the feeding rack to automatically enter and exit the quenching furnace through a railcar and a feeding mechanism. This avoids the synchronous placement of the pallet and the railcar, and improves the continuous working efficiency of the quenching furnace.

Benefits of technology

It improves the continuous quenching efficiency of the quenching furnace, reduces heat loss and energy consumption, stabilizes the furnace temperature, and enhances its utilization efficiency.
