Product Description
Extreme Temperature Graphitization Furnaces - Horizontal Series
Product Introduction
CX-GF series are front loading batch type induction heating furnaces with round or cubic hot zone shape. Cubic hot zones are specially designed for clients who are not satisfied with round hot zones due to some reasons such as dead space.
Maximum operating temperature of 3000°C can meet all demands in carbon material's graphitization treatment.
These furnaces use medium frequency induction heating method. A water cooled induction coil installed inside the furnace. At the center of the coil, there is a graphite crucible as the susceptor for the induction current, surrounded by carbon felt as the insulation material.
Horizontal design of these series, features simple working principle compared to vertical series. The main advantages of horizontal design are easy loading/unloading, easy clean-up of furnace inside, simple operation and maintenance for workers, and easy replacement of consumable spare parts, but the cost of horizontal series is relatively higher than vertical series.
Application
Sintering and Graphitization treatment of carbon materials, synthetic graphite film (Polyimide Graphite Flake and abbreviated PI film), heat conductive materials, carbon fiber rope, carbon fiber, C/C composites, and other carbon materials are only some of the applications of these furnaces.
General Features3000°C extreme temperature which can meet demands for all kinds of graphitization processes.Horizontal front loading with single chamber or multi chambers design for high production capacity. The shell and door are water-cooled jacketed. The furnace shell is made of SUS304 stainless steel. The inner stainless steel wall features long time uses without rusting as well as less adsorption of induction eddy currents in comparison to plain carbon steel.Induction coil covered by high quality alumina coating in order to avoid short circuit between coil and carbon felt.High vacuum pneumatic valves equipped with position indicator in order to automatic control of the vacuum and gas supply system.Over-temperature, over-pressure, gas status, water lack and power failure alarms and automatic mechanical interlock for over-pressure protection.All the running parameters are stored in the PLC system. All stored parameters can be transferred into your personal computer through a USB port.High precision smart temperature controller which can store 20 programs with total 400 segments.International famous brand accuracy pyrometer with temperature measuring range of 1000~3200°C or 600~3100°C. The accuracy of temperature measurement is 0.2~0.75%. Fully automatic PLC monitoring system.Remote operation, failure diagnosis and software upgrading.High automatic equipment, all the on/off switch components and all the running parameters are stored with the digital format in the PLC date base, there have communication interface for the convenience of customer intervene.Patented design for solving the erosion problem of the graphite crucible of the horizontal graphitization furnaces. Our patented design, increased the crucible life in a way that, crucible erosion be less than 5 mm after 60 batches treatment.The specially designed induction coil undergone 5 times insulation process, which completely solved the insulation applicable problem of induction coil under high temperature, and it guaranteed the proper insulation ability under the corundum ageing, break circumstance, it can also effectively prevent the fire on coil and power leakage incident.Optional FeaturesHigh Vacuum System: Vacuum and high vacuum operation of these furnaces is only possible up to 2200°C.Gas Purification SystemClosed Loop Cooling Water SystemDistributed Control System (DCS)Multi chambers (with only one control cabinet for all chambers)Technical Details of Round Hot Zone Models
