Excellent Thermal Performance of RSiC Plate in Kilns
RSiC plates can operate reliably up to 1,620℃. They deliver excellent thermal efficiency and stability inside continuous industrial kilns.
High-purity silicon carbide brings rapid thermal conductivity, ensuring uniform heat distribution while preventing thermal expansion. Moreover, its excellent thermal shock resistance stops micro-cracking during rapid cooling and heating cycles. This also means RSiC plates can be produced thinner to lower kiln thermal mass, substantially reducing fuel consumption.
Packaging for RSiC Plate Transit Safety
Newthink uses customized protective packaging to reduce transit damage for shipped RSiC plates. Our multi-layered packing will prevent impacts, scratches and chipping during international sea/air transport to the greatest extent.
Every plate is wrapped using shock-absorbent foam padding and sealed in moisture-proof plastic. Larger orders are secured in heavy-duty, custom-built plywood wooden crates, which are reinforced with high-density foam boards.
RSiC Plate in Technical Ceramic Industry
A technical ceramics manufacturer faced serious production downtime before. It was caused by traditional kiln plates, which bent and cracked under intense heat.
They found us and upgraded to the high-performance RSiC plate. These new plates perfectly resolved the failures with excellent thermal shock resistance across repeated firing cycles. They can operate continuously without deformation.
With RSiC plates, the factory reduced replacements, significantly improving daily throughput and delivering long-term cost savings.
