Sintering Furnace For Moulded Rods/Tubes

PTFE sintering furnace technical description

Sunkoo supplies drying and sintering furnaces especially for the PTFE processing as well as preheating furnace for Molded rods/tubes.

There is also a furnace available for drying and sintering inline systems for the production of Moulded rods and tubes (development of Sunkoo). This high tech furnace  has an adjustable blind between drying and sintering zone, the lamellas of this blind can be cooled. As these two zones can not be influenced because of the stack affect, the required temperature profile can be well controlled in the drying as well as also in the sintering zone. This sintering furnace is available with different sizes. Herewith the furnace can be adapted to the respective requests and the available space.

5.3.            The sealing material 20 * 20mm high-temperature glass fiber strip seal

 

6.      Furnace Cabinet making

 

Inside the oven using models and stainless steel plate welded together. Wall panels with 1.5mm cold plate, set reinforcing internal ribs. Liner made of 2.0mm stainless steel production base and frame with a 10 channel welded

Long-life heating element made of stainless steel heating tube evenly distributed over both sides of the furnace duct using Choucha installation, wiring head out of the top heating plate outer shell, using nut, rigid fixation, will not fall, set top heating wiring shield. Heating element from front to back is divided into three temperature zones wiring.

Hot air circulation fan installed in the box about four Typhoon aircraft along the longitudinal direction of the furnace are arranged into two, each column 2, the use of ovens with cooling fins with the long axis of the motor, the fan with the overall installation, this type of fan has good stability , low noise, easy installation and maintenance and so on. Fans around the wind guide layer in an oven in the use of wind wheel wind, hot air circulation in the furnace to form a vortex, cabinets ensure temperature uniformity.

Temperature control of the electronic control system is divided into the front to the rear three-zone temperature control, Fuji intelligent digital temperature control instrumentation program accepts thermocouple temperature sensing element signal, PID control power controller controls power adjustment cycle, cycle controller controls the non-contact the opening of the power components solid state relays, solid state relays on and off, to control the heating element that is powered on or off, so as to achieve the purpose of controlling the temperature. Heating circuit configured with AC contact and fuses do secondary protection against solid short-circuit power element damage the equipment. Hot air circulation fan control configuration circuit breakers, AC contactors, thermal relays, start and stop button, withshort circuit, overcurrent, overheating protection, heating control and fan operation interlock to prevent burning heating element. Control system with current, voltage indication, the working status indication.
