Introduction
A high thermal conductivity film graphitization furnace is a specialized equipment designed for the graphitization process of high thermal conductivity films, particularly polyimide (PI) films. This furnace utilizes medium frequency induction heating to achieve rapid temperature rise and high efficiency. Its unique design ensures exceptional temperature uniformity throughout the furnace chamber. The furnace is constructed with double-layer alumina brick insulation to prevent short circuits, providing excellent heat insulation and fire resistance, resulting in minimal heat loss and enhanced equipment stability. It offers the flexibility of configuring multiple electric furnaces with a single power supply, allowing continuous operation by powering on furnaces for heating and powering off for cooling. The furnace is equipped with a digital flow monitoring system for each water channel, ensuring comprehensive protection in the power cabinet. It employs high-performance medium frequency contactors and a PLC-based automatic control and protection system for water, electricity, and gas.
