W Shape MoSi2 Heating Elements

W Shape MoSi2 Heater Description

CVSIC W-Type Molybdenum Disilicide (MoSi2) heating element, shaped like a “W,” is crafted from high-purity MoSi2 using advanced hot-bending technology and a unique formula, with a density of 5.5-6.2 g/cm³ and a maximum operating temperature of 1850℃. Its “three U-shaped” design boasts uniform curvature, wide center spacing, and high hot-end density, making it ideal for horizontal setup in large electric kilns. Aluminum-coated cold ends ensure strong conductivity, while a special surface coating boosts thermal shock resistance and lifespan. It works great for ceramics, electronics, lithium batteries, and high-temperature processing.

W Shape MoSi2 Rod Connection Method

• Contact Surface Design: Both cold ends are aluminum-coated for low-resistance contact and efficient conductivity.
• Electrical Connection: Secure with flat aluminum braid and spring clips, compatible with 220-480V power; use an SCR voltage regulator (for precise temperature control) for best results.
• Note: Ensure connectors fit snugly to the cold end, with connection end voltage <0.01V; pick the right material grade (1700/1800/1850) based on atmosphere type.

• Stable Resistivity: Resistivity remains constant over time, enabling the mixed use of new and old elements.
• Global Service: ISO-certified factory, 360-ton annual capacity, offers free samples, and 7-30 day delivery.

W Shape MoSi2 Bar Installation Method

To ensure the performance and safety of W-Type MoSi2 heating elements, follow these steps:

1. Inspect Element: Check for cracks or damage before setup to ensure the surface coating is intact.
2. Installation Position: Set up horizontally, with three U-shaped bends supported by corundum spacer bricks, and insert cold ends into the furnace, keeping the transition zone unexposed to avoid overheating damage.
3. Spacing Design: Maintain adequate distance from furnace walls and materials (at least 3 times the hot end diameter) to prevent heat buildup.
4. Fixing Device: Use ceramic or heat-resistant steel clips to secure cold ends, with corundum spacer bricks supporting the three U-shaped bends to avoid mechanical stress.
5. Power Connection: Connect the cold end to power with a flat aluminum braid and spring clips, ensuring solid contact and voltage <0.01V.
6. Preheating: Gradually ramp up power during first use to avoid thermal shock.
7. Regular Maintenance: After 2-3 hours of operation, check and re-tighten the connection screws to account for thermal relaxation. Regularly inspect the clips and corundum spacer bricks for stability.

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, ensuring the corundum spacer bricks are correctly placed. Reconnect the wires and refill the refractory material.
4. Gradually heat to ensure regular operation.

W Shape MoSi2 Rod Design Recommendations

To optimize the performance of W-Type 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.
• Shank Spacing Design: Choose a value (standard or minimum) based on diameter for optimal hot-end density and stability.
• Atmosphere Selection: Pick 1700/1800/1850 grade based on 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 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.
• Support Design: Use corundum spacer bricks to support the three U-shaped bends, ensuring even load distribution to prevent deformation.
