1000℃ Vacuum Rapid Annealing Tube Furnace

 Products Description 

Structure Overview

The high vacuum rapid annealing furnace series features a rectangular design. The furnace’s exterior is constructed from cold-rolled sheets, folded and welded for durability. The internal working chamber utilizes a high-purity quartz tube, surrounded by a vacuum-formed alumina fiber insulation. Heating elements are strategically placed within the chamber, and the space between the chamber and the outer shell is filled with 1400-type fiberboard for enhanced insulation. The furnace boasts a double-layer shell structure and integrates the temperature control system directly with the furnace body for streamlined operation.

Sealing Mechanism

The furnace’s sealing system is composed of several critical components:

1. Furnace Body Flange: Post-fabrication, the flange is welded and rigorously tested for leaks using kerosene.
2. Quartz Tube and Flange Seal: A high-temperature silicone gasket ensures a tight seal between the quartz tube and the flange.
3. Exhaust and Vacuum Ports: Located on one side of the flange, these ports are equipped with stainless steel ball valves to control exhaust and vacuum processes.

Technical Specifications

This furnace is designed for a wide range of applications across various industries including ceramics, metallurgy, electronics, glass, chemical processing, machinery, refractories, special materials, and building materials. It is also ideal for academic and research institutions conducting high-temperature experiments, material processing, and quality testing. Key processes include vacuum brazing, sintering, degreasing, and annealing.

Heating and Control
