Glass welded metal vacuum composite plate welded with mounting hole and production method thereof
The invention discloses a glass welded metal composite vacuum plate welded with a mounting hole. The metal composite vacuum plate comprises a shell, core veneers and a cavity, and is characterized in that the mounting hole and an extraction opening are combined, the mounting hole penetrates through the entire composite plate, the shell is made from either alow carbon steel plate or a low carbon steel composite plates and the core veneers are used for providing additional strength to the shell to ensure the smoothness of the shell at barometric pressure, and the vacuum cavity is a closed cavity formed by carrying out glass welding at normal pressure and high temperature and sealing at high pressure to the shell; the sealing is that an extraction opening preformed in the vacuum cavity is automatically sealed by a low temperature solder in a vacuum furnace according to a liquid sealing theory, a low temperature solder comprises a low temperature metal and an alloy solder, the number of the core veneers is at least two and a support is arranged between the core veneers. A production method of the glass welded metal composite vacuum plate provided by the invention is simple in process, the defects of an existing insulation board and an existing vacuum insulated panel can be overcome, and the strength, heat insulation, sound insulation, fire resistance and decorative function can be improved.
