1700°C Atmosphere Controlled Melting Furnace with Stirring and Secondary Charge Feeding Function - VTF-1700X-AD-J

VTF-1700X-AD-J is an atmosphere-controlled bottom-loading box furnace with the functions of secondary charge feeding and stirring. It is designed for melting special glass materials and new alloys up to 1700°C. SPECIFICATIONS Power AC 208 - 240V, single-phase, 50/ 60 Hz, 50 A 8 KW The power cable is included without a plug. Furnace Heating chamber: 200 x 200 x 230 mm (8 x 8 x 8 inches), 8 liters with bottom loading stage ( 100 kg Max.) Double-layer steel airtight case for maximum vacuum and atmosphere control Water-cooled front door and air-cooled shell Built-in pressure gauge, vacuum valves, and two gas float meters Heating elements 6 sets of (30x360mm) MoSi2 heating elements are built-in and replaceable. Working temperature range: 600°C - 1700°C in air or oxygen Note: the heating elements can also be used under inert gas at 1000oC - 1600 oC) The furnace is not a high vacuum furnace. The vacuum level is about 500 torr at high temperature Working Temperature 1700°C(<60min) in air 1600oC in vacuum and inert gases Accuracy: +/- 0.1°C Heating Rate: 10°C / min Thermocouple: dual B-type T/C for control and monitor alarm separately Secondary charge & Stirring The liftable stirring fixture is built on top of the furnace Stirring speed: 0- 50 rpm, adjustable Stirring blade made of BN or Alumina rod Feeder of secondary charge is installed on the top of the furnace for adding 3 types of doping elements during melting Control Panel Built-in PC for controlling temperature and pressure Temperature Control: Eurotherm 3000 controllers with a resolution of 0.1 °C 24 segments programmable A secondary temperature controller is built-in for extra over-temperature protection. Pressure Control: Inert gas purging via manual or automatic mode Constant pressure during heating The pressure control range: -0.06 to 0.03Mpa. Safety Alarm System: Over-temperature protection Over-pressure and low-pressure alert Low water flow alert Data Collection Recording temperature profile Recording pressure profile All data is saved to the hard disk of the PC Local WIFI operation at a remote distance is available upon request Stirring speed and lifting Vacuum pump & Gas Flow Control Two large flow meters are installed on the front panel of the furnace for purging via inert gas One vacuum pump is included to enhance purging and keep the chamber below 760 torr Low vacuum: 10^-1 torr due to fibrous alumina insulation material. Using 5% H2 + Ar will improve oxidation during heating. For oxygen-sensitive material, please use a hydrogen furnace Water Cooling A 58L/min recirculating water cooling is required to cool the furnace sealing flange and chamber case, which is not included Compliance & Warranty CE Certified NRTL or CSA certification is available upon request at an extra cost. One-year limited warranty Dimensions and Net weight Furnace：L800 * W750 * H1500mm Control Unit: 600*600*750 Net weight: 600 kg
