Frequently Asked Questions
What are the key differences between HTAC and HTACG series?
HTAC series are aluminum-carbonaceous composites optimised for thermal shock resistance and steel flow compatibility. HTACG series incorporate ZrO₂ (≥6%) for enhanced slag corrosion resistance, higher density (3.10-3.15 g/cm³), and superior mechanical strength (120 MPa), making them ideal for harsh continuous casting environments with aggressive slag conditions.
Why is carbon content important in these refractory materials?
The ≥7% carbon content provides exceptional thermal conductivity, thermal shock resistance, and chemical inertness. Carbon reduces wetting by molten steel, prevents slag penetration, and ensures rapid thermal equilibration during temperature fluctuations in continuous casting operations. This leads to improved service life and consistent performance.
How do I select the appropriate grade for my application?
Grade selection depends on operating conditions: HTAC-75/80 for standard continuous casting with excellent thermal shock resistance; HTACG-70/75 for aggressive slag environments requiring enhanced corrosion resistance. Higher alumina content (HTAC-80, HTACG-75) provides increased strength and durability for demanding applications.
What quality standards do these materials meet?
All our slip sheets are manufactured under ISO 9001:2015 quality management system and comply with international standards including ASTM C401, JIS R2617, and GB/T 6900. Comprehensive testing includes thermal shock resistance, slag corrosion resistance, and mechanical property evaluation to ensure consistent performance in continuous casting applications.
What is the typical service life in continuous casting applications?
Service life varies based on operating conditions and grade selection. HTAC series typically provide excellent performance for standard continuous casting operations, while HTACG series can achieve extended service life (often 2x longer) in aggressive slag environments due to enhanced ZrO₂ corrosion resistance and higher mechanical strength.
