Vacuum brazing furnace using metal quartz integral radiant heater

Abstract

The invention discloses a vacuum brazing furnace using a metal quartz integral radiant heater. The vacuum brazing furnace using the metal quartz integral radiant heater comprises a furnace body, a vacuum-pumping system, a vacuum heating system and a cooling and tail portion gas collecting system, wherein the vacuum heating system is arranged in the furnace body, the vacuum-pumping system is connected with the furnace body, and the cooling and tail portion gas collecting system is simultaneously connected with the vacuum-pumping system and the furnace body. According to the vacuum brazing furnace using the metal quartz integral radiant heater, a metal quartz integral radiant heating piece which is higher in thermal conversion efficiency, more stable in radiancy and indeformable in high temperature is adopted, and structure arrangement is compact; a plurality of layers of heat insulation protection plates are arranged in the vacuum furnace, heat loss is reduced, and temperature needs for brazing are guaranteed; forced cooling type is short in cooling time, and production efficiency is improved; and the way of recycling use is adopted for used inert gases, leakage is reduced, and high economical efficiency is achieved.

Description

technical field [0001] The invention relates to a vacuum brazing furnace for industrial heat treatment, in particular to a vacuum brazing furnace using a metal-quartz integrated radiation heater. Background technique [0002] Brazing is a long-standing material joining method, mainly used in the manufacture of precision instruments, electrical components, dissimilar metal components and complex thin plate structures (such as sandwich components, honeycomb structures), and is also commonly used for brazing various different wires with carbide cutters. In the manufacture of microwave waveguides, electron tubes and electronic vacuum devices, soldering is even the only possible connection method. Up to the present stage, the development of the brazing industry can be said to have made great progress, and the brazing methods have also been subdivided in depth. According to the types of heat sources and heating methods, there are soldering iron heating, flame heating, resistance ...

AI Technical Summary

Problems solved by technology

2. The cooling of the existing vacuum brazing furnace is generally through the natural cooling method of long-term storage, and the cooling time is relatively long

3. The inert gas (such as argon, etc.) after use is directly discharged, causing waste

These defects are either contrary to the advantages of uniform heating and controllable furnace temperature that the heating method in the furnace should have, or reduce the production efficiency and increase the production cost
