PCD brazing furnace

PCD brazing furnace is a large-scale heat treatment equipment, which can carry out vacuum brazing, vacuum annealing, vacuum aging and other processing. Several different programs can be programmed to control and program hundreds of heat treatment curve points, which are divided into six zones: upper, lower, left and right, front and rear. There are multi-point and single point temperature recorders and over temperature protection devices. The furnace temperature uniformity can be controlled within ± 3 ℃, and the high-purity nitrogen high flow forced cooling device is also provided. The equipment has the advantages of large furnace loading capacity and high efficiency, and no supplementary process is needed for complex parts and parts with special requirements.

PCD brazing furnace is mainly used for vacuum brazing of aluminum products such as aluminum alloy heat exchanger, brazing of stainless steel, titanium alloy, cemented carbide, high temperature alloy, non-ferrous metal, vacuum tempering of high-speed steel, tool and die steel, bearing steel, stainless steel, aging and annealing treatment of non-ferrous metals, and vacuum brazing of stainless steel heat exchanger, oil cooler and stainless steel heat preservation cup.

The vacuum system of vacuum brazing furnace is mainly composed of vacuum chamber, pump system, control valve and heat exchanger. The pump system consists of mechanical pump, maintenance pump, roots pump and diffusion pump. The valve consists of front stage valve (butterfly valve), bypass valve (butterfly valve), maintenance pump valve (butterfly valve) and high valve (plate valve). Each valve is pneumatic valve, which is controlled by PLC pneumatic valve.
