Question: Multi-Stage Program: Does it support multi-stage stepped heating/cooling? How many process recipes can be stored?

Detailed Answer:

Modern R&D and production of new materials place extremely high demands on thermal processes. Simple heating and cooling can no longer meet these requirements. Our graphitization furnace is equipped with a powerful multi-stage program control system, providing precise support for executing complex process curves.

I. Powerful 64-Step Program Control Capability

The system supports programming up to 64 steps, allowing you to break down the entire process into dozens of detailed stages. Each step can be independently configured with:

• Target Temperature/Time: Set to heat to a specific temperature or hold at a certain temperature for a defined duration

• Heating/Cooling Rate: Supports constant rate control (e.g., °C/minute) or direct time setting

• Atmosphere Parameters: Can simultaneously set pressure or gas flow for that step

• Wait Conditions: Can set conditions that must be met before proceeding to the next step

This functionality is particularly suitable for complex processes requiring stepped heating, multi-stage soaking, and slow cooling, such as graphitization of carbon fibers and preparation of high-performance graphite materials.

II. Convenient Recipe Management System

The control system features built-in storage space for 20 process recipes, allowing you to save proven process parameters (including temperature curves, atmosphere control, and all other settings) as specific recipes.

Practical Value:

• Improved Efficiency: When producing different products, operators simply call up the corresponding recipe from the interface, eliminating the need to re-enter complex parameters

• Consistency Assurance: Avoids manual input errors, ensuring process consistency across different production batches

• Access Control: Important recipes can be encrypted to prevent unauthorized modifications

III. Typical Application Scenario Examples

• Carbon Fiber Graphitization: Room temperature → 300°C (slow resin removal) → hold at 300°C → 800°C (medium rate carbonization) → hold at 800°C → 1500°C (medium rate) → hold at 1500°C → 2800°C (rapid graphitization) → hold at 2800°C → slow cooling

• Anode Material Processing: Multi-stage precise temperature control ensures ordered material structure, enhancing battery performance
