Continuous Carbonization Furnaces
Product Introduction
CX-CCF series are continuous furnaces with resistance heating method. These furnaces are specially designed for carbon fiber production.
Applications
Continuous carbonization of carbon fiber at high temperature.
General Features
● Furnace designed especially for high temperature carbonization of carbon fiber. All key special requirements for this process take into account in design of these series.
● Easy installation and maintenance.
● Muffle made of high density graphite in order to have in-direct radiation heating for better temperature uniformity and as well as waste gas management.
● 9 - 12 heating zones, of which 6 - 9 heating zones are controllable within the range of 500-1600°C. The other heating zones are used for cooling steps.
● The furnace mouth can be segmented.
● The temperature gradient and uniformity is guaranteed for proper setting of processing materials, which make sure there is no material shrinkage or expansion problems.
● High density graphite heating elements are uniformly distributed to ensure temperature uniformity in the hot zone. Heating elements powered by direct current (DC) switch mode power supply with low voltage (<50V) which increase heating element life in comparison to use of AC transformers. The power of the hot zone is regulated through the phase shift thyristors.
● High quality rigid graphite felt as the insulation of the hot zone.
● Delicate measurement system for oxygen content in protective gas and dew point tracking.
● 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.
● Fully automatic PLC monitoring system.
● Remote operation, failure diagnosis and software upgrading.
● Multi zones design for higher temperature uniformity.
Optional Features
● Gas Purification System
● Closed Loop Cooling Water System
● Distributed Control System (DCS)
● Multi chambers (with only one control cabinet for all chambers)
● Tail gas treatment system
