1. Clear usage requirements
Heating temperature: Determine the heating temperature range you need. There are usually different temperature series for crucible electric furnaces, such as the 1000 degree series, 1200 degree series, 1400 degree series, and 1700 degree series. When choosing, ensure that the selected electric furnace can meet your maximum temperature requirements.
Volume size: Choose the appropriate volume size according to the needs of the experiment or production. Electric furnaces of different volumes are suitable for operations of different scales.
Material requirements: Consider the materials of the crucible and furnace. Common crucible materials include graphite, silicon carbide, etc., while furnace materials include silicon carbide, ceramic fibers, etc. Choosing appropriate materials can improve the service life and heating efficiency of equipment.
2. Consider device performance
Heating element: Understand the types of heating elements for electric furnaces. Electric furnaces with different temperature ranges use different heating elements, such as alloy heating wires (below 1200 degrees), silicon carbon rods (1400 degrees crucible furnace), silicon molybdenum rods (1700 degrees crucible furnace), etc.
Temperature control system: Check whether the temperature control system of the electric furnace is accurate and reliable. Modern electric furnaces are usually equipped with intelligent multi-stage programmable temperature control systems, which can provide more accurate temperature control.
Safety performance: Consider the safety performance of the electric furnace, such as whether it has functions such as over temperature alarm and power-off protection. These functions can ensure timely power-off in case of abnormal situations, protecting the safety of equipment and operators.
3. Compare different brands and models
Brand reputation: Choose products from reputable brands that typically have better product quality and after-sales service.
Cost effectiveness: Compare the cost-effectiveness of different brands and models while meeting usage needs. Consider factors such as equipment price, performance, and lifespan, and choose products with high cost-effectiveness.
User reviews: View other users’ reviews and usage experience of the product to understand its advantages, disadvantages, and scope of application.
4. Actual operation and inspection
Trial or demonstration: If possible, suppliers can be requested to provide trial or demonstration services to gain a more intuitive understanding of the performance and operation of the equipment.
Check the equipment: Carefully inspect the appearance, internal structure, and accessories of the equipment before purchasing to ensure that there is no damage or defect.
5. After sales service
Warranty Policy: Understand the warranty period and scope of the product, so that timely repair or replacement can be obtained in case of equipment problems.
Technical support: Inquire with the supplier if they provide technical support and training services so that you can receive timely assistance and guidance in case of any problems encountered during use.
