AI Technical Summary

Technical Problem

The existing single crystal furnace auxiliary furnace chamber has a fixed length design, which is insufficient for large-size crystal rod growth and special processes, affecting the uniformity and quality of crystal growth, and also makes it impossible to flexibly adjust the production process, increasing production costs.

Method used

A height-adjustable auxiliary furnace chamber structure is designed, which enables flexible installation and disassembly of the height-adjustable furnace chamber through slots, convex rings and locking components, thereby increasing the auxiliary furnace chamber space, optimizing airflow distribution and temperature field, and using support rods and limit rings in conjunction with fasteners to ensure a stable connection.

Benefits of technology

It enables flexible adjustment of the auxiliary furnace chamber space according to production needs, improves crystal growth uniformity and quality, reduces production costs, and avoids the need to replace the entire set of equipment.

Abstract

This utility model relates to the field of single crystal furnace technology, and in particular to a heightened auxiliary furnace chamber structure for a single crystal furnace. It includes a lower furnace chamber, an upper furnace chamber, a heightened furnace chamber, and a locking assembly located above it. The lower and upper furnace chambers each have a slot on their relatively adjacent sides, and a first flange ring is fixedly connected to each of the relatively adjacent ends of the lower and upper furnace chambers. In this application, the lower furnace chamber, upper furnace chamber, and heightened furnace chamber cooperate through the slots, a second convex ring, and the locking assembly. The heightened furnace chamber can be flexibly installed or disassembled according to actual production needs. When large-size crystal rod growth or special processes are required, adding a heightened furnace chamber increases the auxiliary furnace chamber space, meeting the special process requirements such as large-size crystal rod growth, optimized airflow distribution, and temperature field, improving the uniformity and quality of crystal growth. Furthermore, when upgrading and adjusting enterprise processes, it is not necessary to replace the entire single crystal furnace equipment, reducing production costs.
