We can offer custom-made furnace.Structure descriptionThe electric furnace is heating vertically (The pressure is from 5T to 100T, two ways of pressure : one and two way ) , and It also has two way of feeding and discharging : from the top or the side . It consists of furnace shell , heating element , insulation layer , pressure device , vacuum system , electric control system and so on.1. The furnace shell is in dual layer water-cooled structure with inner layer of polishing stainless steel and outer layer of high-quality anti-rust carbon steel . There passes water between the two layers to cool the furnace to ensure the temperature of the furnace shell is under 60C. The furnace cover is completed hoisting by upgraded the mechanical structure and opened manually by rotating to back (one-way pressure) . the furnace cover is equipped with a locking device.2. It is equipped with an observation window (OBW), thermocouples automatic access structure , infrared thermometer and water-cooled electrodes (three phase). Thermocouples automatic access adopts electric mode, which has the function to automatically switch high and low temperature . In case that prevent abnormal furnace temperature causes accident , it is also equipped with over-temperature protection thermocouples.3. The heating elements are made of graphite tube (or molybdenum wire,induction) , which is divided into two kinds : single phase and three phase heating . The heating element is designed reasonably to improve the temperatures uniformity.4. The insulating layer is made of graphite (or graphite paper) and carbon felt , and has good insulation function . With the unique designed structure , it would reduce the vacuumizing time . The molybdenum wire hot pressed furnaces insulating layer is the metal reflective screen.5. The vacuum system is made of secondary vacuum pump , with one oil diffusion pump and a mechanical vacuum pump to achieve the high and low vacuum degree. The vacuum valve is made of high vacuum flapper valve which is designed and produced by our company. With the digital displayed vacuum gauge and PLC ,it can achieve automatic switching and control of the high and low temperature.6. The major loop of electric control system adopts low-voltage high current input method , and the electric control cabinets design refers to the Siemens standard control cabinet , with human design , graphic simulationg screen and push bottom on the control panel , which is operated directly and conveniently. The temperature and pressure control machine are imported brand process control instrument . In the cabinet ,it is equipped with PLC , which could automatically sinter according to the presetting default procedures . The control system has protection functions of sound and light alarm when such abnormal phenomena occurred as water break, over temperature,over-current , automatic switch failure of thermocouples and so on.
