Being small-size laboratory equipment customized with universities and scientific institutes in cooperation.
Application：Experimental graphitization furnace is applied for sintering and graphitization of carbon materials, sintering of carbon fiber rope, sintering and graphitization of carbon fiber heater and production of material sintered under carbon environment Other materials to be sintered under other carbon environment.With high heating efficiency and good operability, the furnace is also used for experiment, scientific study and teaching demonstration.
Characteristic：
●It also occupies small area and works with low noise and low energy consumption.
●The less than 3000°C ultra-high temperature furnace body fully meets the requirement for sintering and graphitization of a variety of materials.
●IGBT series connected induction is adopted for heating with low ultra-harmonics, contamination to power grid and without interference to electronic equipment.
●The product saves electric energy by 15% compared with outdated SCR medium frequency power.
●The programmable controller and man-machine interface realizes automatic operation throughout the process and support fully automatic/semi-automatic/manual modes.
●The comprehensive PLC water, power and air automatic control and protection systems have ultra-high temperature sensor break performance water pressure and furnace excessive pressure, water flow and excessively high water temperature sound-light alarm performance
