Vacuum Graphitrohrofens

Vacuum Graphite Tube Furnace Usage The vacuum graphite tube resistance furnace is periodic operating type electric furnace. ItUsing graphite as the heating elements high temperature and high vacuum resistance furnace. Its power is 25 or 50 kilowatts, and rated temperature is 2500. It can be used for eating metal, refractory compound and the ceramic material etc in the vacuum or the protective atmosphere. Feature Unique heating elementsstructural arrangement and reasonable and effective heat shield guarantee the high heating effect and temperature uniformity.Unique insulation construction, energy saving, long in service life.The unique integration of water and electricity connecting structure has the featuresof low malfunction, artistic, debugging quickly, maintenance convenience.The unique fast cooling syatem can reduce the furnace temperature quickly and improve the production efficiency. It is only cost more than 2 hours to reduce the temperature from 1000 to 100.The simulation operation interface and PLC are adapting the productive needs. The perfect security system andunusual warning syatem make the equipment have high reliability, easy to maintain and control.Structure The electric furnace is vertical vacuum resistance furnace, it is composed by furnace stack,furnace cover, vacuum system, electrical system and water-cooling system.The furnace stack uses the water cooling sandwich structure, the furnace cover can be openedby spring force.The furnace body is equipped with two observation windows, which can observe the workpiece heating situation.The graphite electrode is loaded in the furnace, which is made up of two mutually insulated semicircles. The two insulated semicircles with the graphite heating element opens several seal thin at its longitudinal to increase resistance and make one side of the heating element electrify, and the other side free expansion when heating.around the heating element, thre are many multi-layered heat shield device, which are assembled together to make it convenient to take outside the furnace.The vacuum system is made up of proliferates pump, mechanical pump as well as the vacuum valve and so on.The vacuum survey uses thermocouple gauge or ionization vacuum gauge.The electrical system is made up of the silicon-controlled voltage regulator and the low voltage transformer and the control cabinet.Technical Parameter NameUnitTypeTHVCDRated Power KW2550Power Voltage VSingle phase 380Single phase 380Rated Voltage VSingle phase 028Single phase 036Rated Temperature °c20002000Thermalvacuum Level mmHg5×10-45×10-4Cool Ultra Vacuum Level mmHg5×10-55×10-5Working ZoneDiameter mmmm90120140160Deepth Empty Furnace Power LossKW≤23≤36Pressure Rate umHg/min≤0.5≤0.5Overall Size Lengthmmmmmm1350780154013507801540Width Height Weight kg575575Remark: we can produce non-standard industry furnace accoding to customers request.
