Powder metallurgy protective atmosphere sintering furnace for the production of molding powder metallurgy products, sintering process and the special equipment for continuous operation under controlled atmosphere protection. This equipment can be divided into a furnace, belt drive, Appliance control of three parts, the working characteristics of the workpiece by the mesh belt from the feed port into the sintering zone, in each thermostat region sintering, and then cooled, the material will complete the entire process.
Powder metallurgy protective atmosphere sintering furnace body structure
Powder metallurgy sintering furnace protective atmosphere furnace into the feed intake, the sintering zone, the discharge of water cooling jacket, the furnace shell and skeleton welded steel plate and steel furnace and the furnace shell with good insulation properties of silicon acid aluminum fiber insulation layer, ultra-lightweight anti-carburizing the firebrick refractory layer, with good strength and fire resistance. Placed in the furnace high temperature, corrosion-resistant corundum pallets, high strength, not easy to deformation. The heating elements Cr20Ni80 material, are installed in the lower part of the corundum pallets wear will be easy to replace the resistance wire, sliding roller and adjusting screw mounted in the discharge water cooling jacket, the height can be adjusted from the impact of any force , to prolong the service life of the equipment package.
Powder metallurgy protective atmosphere sintering furnace mesh belt structure
Processes of powder metallurgy sintering furnace protective atmosphere with all the network transmission, using imported 310S high temperature stainless steel wire mesh belt around the system, feed port is equipped with mesh belt transmission mechanism, the workpiece through the feed inlet, sintering zone, the cooling water jacket, the discharge port, mesh belt driven wheel around the spout to return to the feed inlet, the lower part of the furnace, mesh belt speed two-stage pendulum pin reducer reducer FM motor running speed can be arbitrarily changed.
Powder metallurgy protective atmosphere sintering furnace control system
Powder metallurgy sintering furnace protective atmosphere electrical control system is controlled by SCR PID automatic temperature control, power and temperature of each temperature zone can be individually controlled and adjust to meet the iron-based sintered process technology requirements, and with overcurrent protection, Fast Acting, overvoltage protection, the RC circuit. Temperature controller with intelligent digital instrument, temperature control accuracy of ± 1 ℃, with over-temperature alarm system.
