AI Technical Summary

Technical Problem

In the existing quartz crucible melting process, the gap between the rotating molding die and the water-passing plate causes heat to be lost to the outside, resulting in reduced equipment operating efficiency, increased maintenance costs, and safety hazards.

Method used

The system employs a combination structure of a water-passing plate and a heat insulation plate. The heat insulation plate is filled with circulating cooling water and connected by hinges and adjustment parts to form a heat insulation zone, blocking the heat radiation and convection heat dissipation path. A barrier is constructed using 304 stainless steel to reduce heat diffusion.

Benefits of technology

Significantly reduces energy loss, improves electrical energy utilization, extends equipment life, reduces the risk of impurity introduction, enhances product quality, shortens process time, and reduces energy consumption and maintenance costs.
