• Flexible Customization: Supports custom shapes and sizes to fit complex furnace designs.
• Corrosion Resistance: Low porosity (7.4%) and water absorption (0.2%) make it suitable for various atmospheres (air, inert gases, etc.), enhancing its durability.
• Global Service: ISO-certified factory, 360-ton annual capacity, offers free samples, and 7-30 day delivery.

Straight Type MoSi2 Elements Installation Method

To ensure the performance and safety of Straight MoSi2 heating elements, follow these steps:

1. Inspect Element: Check for cracks or damage before setup.
2. Installation Position: Place the cold end in the furnace, keeping the hot end centered in the chamber at an adequate distance from the furnace walls and bottom (at least three times the diameter of the hot end).
3. Fixing Device: Use ceramic or heat-resistant steel clips to secure cold ends, avoiding mechanical stress.
4. Power Connection: Connect the cold end to power using a flat aluminum braid and spring clips, ensuring a solid connection.
5. Preheating: Gradually ramp up power during first use to avoid thermal shock.
6. Regular Maintenance: Check connectors and clips for loosening or corrosion; re-tighten screws after 2-3 hours of operation to handle thermal relaxation.

Replacement Steps

1. Locate the damaged element and prepare a replacement set.
2. Disconnect the power, remove the aluminum braid and connecting screws, and clear the refractory material and plugs.
3. Insert a new element from the furnace top, reconnect the wires, and refill the refractory material.
4. Gradually heat to ensure regular operation.

Note: Professionals should perform installations and replacements. Contact us for detailed guidance.

Straight Type MoSi2 Heater Design Recommendations

To optimize the performance of Straight MoSi2 heating elements, follow these suggestions:

• Length Matching: Ensure Lu (150-1000mm) and Le (150-1500mm) match furnace dimensions, avoiding hot end insertion into furnace walls.
• Atmosphere Selection: Select a grade of 1700/1800/1900 based on the atmosphere (e.g., O2, N2, H2), referring to the maximum temperature table.
• Spacing Design: Maintain a clearance of at least three times the hot end diameter between the element and the furnace walls/materials and at least four times the diameter for center-to-center spacing to optimize heat distribution.
• Temperature Control System: Utilize a PID controller for precise temperature control to prolong the element’s lifespan.
• Cold End Protection: Ensure the cold end aluminum coating is intact and that the connectors are tightly secured to prevent poor contact.
