Continuous Carbonization Furnaces

Continuous Carbonization Furnaces

 Product Introduction

 

CX-CCF series are continuous furnaces with resistance heating method. These furnaces are specially designed for carbon fiber production.

 

Application

 

Cxinduction’s capabilities extend from thermal equipment designs for a specific unit operation through fully integrated production lines producing carbon fiber, carbon nanotubes, and metal oxides.Fully Integrated Control Systems.

 

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.

· Gas flow control 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.

· 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

Carbonization Furnaces

Product Introduction

CX-CF series are batch type resistance heating furnaces with round or cubic hot zone shapes. Round hot zones used in vertical models while cubic hot zones used in horizontal models. Horizontal models with cubic hot zone shape are specially designed for Polyimide Film carbonization.

 

Maximum operating temperature of 1600°C can meet all demands in carbonization processes.

Use of high density and high purity graphite heating element along with high quality insulation carbon felt, features long life hot zone. Multi zones design of these furnace ensure uniform heating inside the hot zone. These furnace can operate under inert gas, vacuum or high vacuum (optional) atmospheres.

 

Application

 

These furnace are mainly used for Polyimide Film carbonization, C/C composites, graphite hard felt, carbon fiber, and medium and low temperature carbonization of graphite materials and parts.

 

 

General Features

 

· Vertical Top Loading Vertical Bottom Loading and Horizontal Front Loading with single chamber or multi chambers design for high production capacity. The shell and door are water-cooled jacketed. The outer layer of the furnace shell is made of carbon steel while the inner layer is made of SUS304 stainless steel.

· Stable hydraulic lifting system for the chamber door or bottom. Ground guide rail and skip car for bottom loading models.

· High vacuum pneumatic valves equipped with position indicator in order to automatic control of the vacuum and gas supply system.

· Gas flow control 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.

    · Fully automatic PLC monitoring system.

    · Remote operation, failure diagnosis and software upgrading.

    · Multi zones design for higher temperature uniformity.
