Stanard Structure

Furnace body	The furnace body and furnace cover are double-wall water-cooled structures, and the inner and outer walls are made of carbon steel. There is a gap between the two layers, with cooling water inside, the front end connected with the flange of the furnace mouth, and the rear end connected with the sealing head, leaving a flange interface with the air-cooled motor at the rear end of the furnace body. In the lower part of the furnace body, a bracket for the furnace body is designed to place the furnace body. The following openings are provided on the furnace body * Evacuation hole * Electrode openings * Thermocouple hole * Inflatable hole * Pressure measuring hole * Safety valve mounting hole * Other auxiliary openings * Special burner holes in the front door, * Specially designed hole in the lower part of the furnace
Furnace door	The seal between the furnace body and the furnace door is designed as a two-way seal of the lock ring. The seal ring is installed in the groove of the furnace door flange to ensure the vacuum furnace sealing under negative pressure and high pressure air cooling.
Heating elements	The heating element is made of graphite tubes. The heating elements are evenly distributed along the inner wall of the heating chamber, ensuring long-term use without deformation, long service life, and at the same time ensuring the uniformity of heating.
Heating chamber	The heating chamber consists of a heat insulation layer, a heating element, a material table and other parts. * The heat insulation layer(50mm) is a round structure composed of three layers of graphite felt(30mm) and high-temperature shaped composite hard felt 20mm graphite hard felt. Graphite felt is fixed on the heating chamber frame by molybdenum nails. The heating chamber is a 360-degree circular uniform cooling method. Both front and rear heat insulation doors are provided. The heat insulation door has the same structure as the heat insulation layer. * The hearth is made of graphite. Two horizontally distributed hearths are provided with gaskets made of boron oxide to isolate the material basket from the hearth.
Vacuum System	The vacuum system consists of 2H-15B slide valve pump, ZJ-600 Roots pump, vacuum valve installed on the evacuation pipeline, differential pressure valve, flexible connecting parts and other accessories consisting of medium vacuum machine. Ultimate vacuum up to 4.0×10-1Pa.
Electrical Control System	Electrical control system: This system consists of two parts, voltage regulator, thyristor and temperature programmable controller, programmable temperature control and PLC programmable mechanical action, which can realize automatic program operation. Both manual operation function cylinder control and limit, control lock cylinder design has magnetic switch, control vacuum pipe bypass valve, main road valve, cylinder design with magnetic switch, inflate, deflate, quick cooling air valve, part design There are magnetic switch limit, whether to open and close during work, can be seen on the industrial computer is closed and open, and faulty industrial computer shows, the line position is in place.
Including	1SET furnace body(furnace body, heater, chamber etc..) 1SET control cabinet 1SET vacuum system(pumps and valve) 1SET water-cooling system(pipeline) 1SET operation manual

Brazing is the oldest method for joining metals, other than by mechanical means. Initially, the process was most popular for joining gold and silver base metals. Lead and tin, as well as alloys of gold-copper and silver-copper, were used as filler metals because of their low melting points. Copper hydrates and organic gums were added later because of their reducing action, which helped to minimize oxidation and improve the cosmetic appearance of the joint. Metallic salts were also used. Later, alloys of brass and copper were introduced as filler metals because of their ability to produce higherstrength joints in copper and steel structures, which were also able to withstand high temperatures. As brazing technology advanced, many other filler metals have evolved.
