Flagship Micro-Pore Technology for General-Purpose Lines:Maximum pore size is strictly controlled to ≤0.05 mm—identical to our high-grade series—which physically prevents oxide particle embedding and nodulation, delivering premium surface quality to mid/low-grade silicon steel production without requiring ultra-high temperature capability.

Wet Atmosphere Compatibility Without Compromise:Unlike high-grade dedicated sleeves restricted to dry atmospheres, this CSNG composite is explicitly engineered for both dry and wet conditions up to 950°C—eliminating the need for different sleeve types when humidity varies across furnace sections or production schedules.

Thermal Expansion Control for Thermal Shock Resistance:Precisely engineered coefficients of thermal expansion (3.0 for LT, 3.5 for MT) ensure synchronous movement with metal roll cores during temperature cycles, preventing cracking and unplanned downtime—even in facilities with frequent startups and grade changeovers.

Enhanced Strength for Improved Reliability:Flexural strength of 18–22 MPa and compressive strength of 35–40 MPa represent a 20–30% improvement over standard medium-fine sleeves, providing the mechanical robustness needed for higher line speeds and consistent strip support throughout extended campaigns.

Superior Density for Extended Service Life:Ultra-low apparent porosity of 13–14% combined with bulk density of 1.75–1.78 g/cm³ creates an exceptionally dense matrix that slows oxidation and wear—delivering significantly longer service life than conventional alternatives in the same application.

Optimized Graphitization for Strip Protection:Graphitization degree of 75–95% provides enhanced self-lubricating properties that minimize friction against the steel strip, reducing surface scratches and protecting finished product quality—critical for producers targeting premium market segments with mid-grade materials.

Dual Temperature Grades for Application Matching:Available in LT (≤900°C) and MT (≤950°C) versions with distinct thermal expansion coefficients, allowing producers to select the exact specification that matches their process conditions without paying for over-engineered ultra-high temperature performance.

Homogeneous Microstructure for Predictable Performance:CSNG isostatic pressing technology ensures uniform density and structure throughout the entire sleeve body, eliminating weak points and delivering consistent, repeatable performance across multiple installations—simplifying maintenance planning and inventory management.

Premium Performance at Mid-Grade Investment Levels:By bringing flagship technologies—micro-pore control, thermal expansion matching, and ultra-dense structure—to the mid/low-grade segment, this composite sleeve delivers measurable reductions in per-ton production costs while elevating output quality toward high-grade standards.
