I、Equipment Introduction

This equipment is a horizontal high-temperature carbonization furnace, which is mainly used for carbonization of polyimide films, carbon/carbon composites, graphite felt, carbon fiber, graphite materials and products at medium and low temperatures. The equipment consists of a furnace body, heating system, charging and discharging system, vacuum system, electrical control system, water cooling system, transformer, and connecting cables.

II、Equipment advantages

1. Temperature field design: High purity graphite is used as the heating element for heating, arranged around to ensure the stability of the temperature field; High purity graphite has high purity and no volatilization, effectively ensuring the cleanliness of the furnace chamber. The insulation material uses high-strength graphite soft felt to wrap the crucible (graphite board), which has good insulation effect and impact resistance. The entire insulation screen is fixed with a metal frame for easy installation and maintenance. The temperature control adopts tungsten rhenium type thermocouples, which have high reliability, wide applicability, and long service life.

2. Design of condensation, degreasing and filtration system: the double outlet condensation, degreasing and filtration system is adopted, and the suction port is connected to the chamber through the pipe, and converged to the screw pump+Roots pump vacuum system after passing through the copper tube fin condenser device, steel ball/scouring cloth filter device and K3250 filter device. Ensure optimal pumping speed and filtration efficiency.

3. Electrical control system design: The electrical control system consists of touch screen, electrical cabinet, contactor, transformer, thyristor module, temperature control meter, indicator light, PLC and other components. The main brand is Chint or the same level brand. The temperature control meter adopts a European brand programmable intelligent temperature adjustment instrument, with a temperature control accuracy of ± 1 ℃. It has functions such as PID adjustment, over temperature alarm, broken couple indication, and temperature compensation.
