Product Overview
This graphite block is specially designed for the #1 inlet seal position of industrial kilns, manufactured in strict accordance with NCC drawing NCC-KL-91. Made of high-purity fine-grain graphite, it delivers excellent high temperature resistance, thermal shock stability and self-lubricating performance, ensuring reliable sealing performance under continuous high-temperature working conditions of kiln equipment. It is an ideal OEM replacement part for cement, metallurgy and chemical processing kiln systems.
Key Features
- Manufactured per NCC drawing NCC-KL-91 with precise dimensional tolerance for perfect fit
- High-purity graphite material, resistant to high temperatures up to 1000°C in non-oxidizing environments
- Outstanding self-lubricating property reduces friction and wear at the seal interface
- Excellent thermal shock resistance, stable performance under rapid temperature changes
- Good chemical corrosion resistance, compatible with most kiln process media
- Precision machined surface ensures tight sealing and minimal gas leakage
