Product Introduction 
The Ash Furnace operates on the resistance heating principle. The specially treated heating elements provide high heating efficiency, rapid temperature rise, and uniform temperature distribution. The intelligent digital temperature control system precisely sets and automatically controls the furnace temperature, reducing human reading and operation errors. The integrated structure combines the furnace body and controller into one aesthetically pleasing and easy-to-operate unit. The equipment can be used for ash content determination of pulp and paper, as well as ignition, drying, and heat treatment experiments for other materials.

FAQ 
1. What are the main applications of the Ash Furnace?
It is mainly used for ash content determination of paper, pulp, and other materials, as well as for combustion, degassing, drying, sterilization, stabilization treatment, and high-temperature ignition experiments for various materials.

2. The heat-up time of 10-20 minutes refers to what target temperature?
It typically refers to the time required to heat from ambient temperature to 1000°C, approximately 10-20 minutes. The actual time may vary depending on the set target temperature and environmental conditions.

3. How to set and control the temperature?
Set the target temperature via the digital display control panel. The intelligent temperature control system automatically adjusts the heating power to quickly reach and maintain the set temperature with high precision and simple operation.

4. What safety precautions should be observed during use?
Before use, confirm the power supply is 220V/50Hz with reliable grounding. The furnace surface temperature is high during operation; do not touch it. Use dedicated tools and wear protective gloves when placing or removing samples. The equipment should be placed on a flat, well-ventilated workbench away from flammable and explosive materials.

5. How should the furnace hearth be maintained and cleaned?
After use, allow the hearth to cool to room temperature, then clean residual ash and debris with a soft cloth or brush. Avoid washing the hearth interior with water. Periodically check the hearth for cracks or spalling; if abnormalities are found, contact after-sales service promptly.

6. What if the digital display is abnormal?
First, check that the power connection is normal. If the display remains abnormal, there may be a sensor fault or controller problem. Contact our after-sales team for remote diagnosis or on-site inspection; do not disassemble the controller yourself.
