Abstract

The invention relates to a vacuum brazing furnace heating chamber, which comprises a hollow horizontal barrel and end covers fixed on two ends of the barrel, wherein one ring of barrel reflecting screen is fixed in a barrel frame; a barrel heating assembly is arranged in the barrel reflecting screen; two ends of the barrel are respectively fixed with one ring of barrel sealing belt; the inner wall of an end cover frame is successively fixed with an end cover reflecting screen and an end cover heating assembly; one ring of end cover sealing belt is fixed on the junction of the end cover and the barrel; the barrel reflecting screen and the end cover reflecting screen are respectively made of multiple layers of stainless steel; and the barrel heating assembly and the heating element of the end cover heating assembly are respectively coiled by a broad-belt nickel-chromium belt. The barrel reflecting screen and the end cover reflecting screen are respectively made of multiple layers of stainless steel, which is favorable for reducing the possibility for heat to outwards diffusing, and furnace temperature evenness is good. The barrel heating assembly and the heating element of the end cover heating assembly are respectively coiled by a broad-belt nickel-chromium belt, heating is even, and heat loss is small.

Description

technical field [0001] The invention relates to a heating chamber, in particular to a heating chamber of a vacuum brazing furnace. Background technique [0002] In the 21st century, human survival and development are increasingly challenged by pressure from the environment and resources. Therefore, it is very important to develop new technologies and processes for energy conservation and environmental protection. In industrial production, some traditional energy-consuming industries have also continuously improved the utilization efficiency of energy and resources through technological transformation and innovation in recent years. For example, in the metal heat treatment industry, in recent years, old and backward production equipment has been eliminated by optimizing the production process. , the use of new technologies and other measures have achieved good results. The most prominent thing is the vigorous development and more and more extensive use of vacuum furnaces in ...
