Kerui Refractory Kiln Furniture Upgrade Project – Mexico Sanitary Ware Factory

A sanitary ware manufacturer in Mexico faced ongoing production issues due to the limitations of traditional kiln furniture. Kerui Refractory provided a complete upgrade solution to improve kiln performance, product quality, and operational stability.

Customer Challenges

The customer had been using cordierite-mullite kiln furniture in a tunnel kiln system. With increased production demands, several problems became more serious:

• Frequent product sticking on kiln shelves
• Gradual deformation under high load conditions
• Short service life and frequent replacement
• Reduced production efficiency and unstable firing quality

These issues had persisted for years and significantly impacted overall production cost and consistency.

Kerui Technical Analysis

After evaluating the kiln conditions, firing temperature, and loading structure, Kerui engineers identified the root causes:

• Material performance limitations under high-load continuous operation
• Insufficient resistance to thermal stress and long-term deformation
• Surface characteristics not suitable for current firing products

Kerui Solution

Kerui Refractory proposed a full kiln furniture replacement solution using high-strength silicon carbide (SiC), including:

• High-load SiC kiln shelves
• SiC beams and structural supports
• Optimized surface design to reduce sticking
• Materials with superior thermal shock resistance and durability

Customer Feedback

The client expressed strong satisfaction with the results, stating that long-standing production issues were finally resolved. The new system improved both product quality and kiln operation stability, supporting continuous and efficient production.
