Product List
Ceramic Roll Series
Ceramic Disk Roll
Ceramic Disk Roll serves as a high-temperature Hearth Roll for diverse applications, including loading, conveying, and forming in high-temperature heating and heat treatment furnaces.
Product Features
- All products are crafted from Non-Asbestos materials
- Rigorous pre-treatment of raw materials prevents dents from foreign object embedding on strip surfaces
- Tailored hardness can be optimized for operating environments based on customer needs
- Low thermal shrinkage ensures stability and deformation-free performance over extended periods
- Excellent insulation properties minimize energy loss
- In-house ceramic material production ensures quality control and a reliable supply chain
Ceramic Disk
KRST provides complete technical support from material selection to installation, tailored to the customer’s requirements and on-site operating conditions.

Application Lines
- Stainless Steel Heat Treatment Furnace APL (Annealing & Pickling Line)
- Heat Treatment Furnaces for Carbon Steel, Electrical Steel Sheets, and Non-ferrous Metals (ACL, DNL, CAL)
- Glass Heat Treatment Furnaces (Forming Line, Annealing Lehr)
Production Process
Product Structure
- Ceramic Disk: Each disk is compressed and assembled; the roll surface contacts the material during operation.
- Shaft: Water-cooling type.
- Flange: Compresses and fixes the ceramic disks onto the shaft.
Ceramic Sleeve Roll
A high-temperature Hearth Roll using ceramic sleeves made of Fused Silica, Alumina, or Zirconium.
It is specially designed to compensate for the different thermal expansion coefficients between the ceramic sleeve, metal shaft, and flange, enabling stable long-term operation under high-temperature conditions.
Product Features
- Anti-dent
- Anti-shaft sagging
- High heat resistance and excellent wear resistance
- Special roll design for an optimal combination of steel shaft and ceramic sleeve
Applications
- Silicon Steel Furnace (ACL, DNL)
- Hot Stamping Lines for Automotive Steel
- Glass Manufacturing Furnaces
GRAPHITE SLEEVE ROLL
Graphite Sleeve Rolls are manufactured by machining carbon-based materials into sleeve form and assembling them onto the roll.
They make use of carbon’s inherent properties such as high thermal resistance, high chemical stability, excellent lubricity, and low thermal expansion, and are widely used as rolls in high-temperature environments.
Product Features
- Can be manufactured with the highest purity.
- Low surface wetting against molten metals
- Excellent thermal and chemical resistance
- Superior resistance to thermal shock
- High lubricity, good friction characteristics, and high thermal conductivity
- Increased strength at elevated temperatures
- Easy to machine
Applications
- Silicon Steel Furnace (ACL, DNL)
- STS BAL
- Non-oxidizing Furnace Hearth Rolls
