Solving Key Operational Pain Points in Continuous Casting

Conventional slide gate plates often suffer from poor thermal shock resistance, high-temperature cracking, insufficient slag erosion resistance and inadequate surface flatness. These common defects frequently cause molten steel penetration, surface spalling, sliding jamming and premature failure. Resulting unplanned shutdowns, frequent part replacements and inconsistent casting continuity not only increase operational and procurement costs, but also raise major safety risks such as steel leakage and splashing, leading to substantial economic losses for steel plants.

To address these industry pain points, JI-STEEL has established rigorous R&D and production standards for refractory components. Our slide gate plates adopt high-purity alumina-carbon and alumina-zirconia-carbon composite materials, manufactured through precision batching, high-pressure forming and ultra-high-temperature sintering processes. Each plate undergoes multi-stage precision grinding, ensuring superior flatness, tight interfacial fitting and consistent sliding performance. This eliminates jitter and mechanical offset, enabling stable long-sequence and multi-heat continuous casting.

Core Product Advantages for Diverse Steelmaking Conditions

Engineered to withstand extreme high-temperature and high-intensity casting environments, JI-STEEL slide gate plates outperform standard industry alternatives and are fully applicable for carbon steel, alloy steel, stainless steel and clean steel production.

1. Outstanding Thermal Shock and High-Temperature Resistance
   Our plates maintain stable structural integrity under sustained temperatures above 1600°C and rapid thermal cycling. They effectively resist cracking, delamination and peeling, delivering consistent performance throughout long casting campaigns.
2. Superior Slag and Molten Steel Erosion Resistance
   The advanced composite material formula significantly improves chemical stability and physical abrasion resistance. It effectively withstands continuous scouring from molten steel and corrosive slag, extending service life and increasing the number of continuous casting heats per set.
3. High-Precision Sealing for Maximized Operational Safety
   Precision-machined contact surfaces ensure tight, uniform fitting under high-temperature working conditions. This reliable sealing completely prevents molten steel penetration and leakage, establishing a solid safety guarantee for continuous casting operations.
4. Wide Adaptability and Customized Engineering Support
   Our slide gate plates are compatible with mainstream ladle and tundish slide gate systems. We provide fully customized dimensions, opening configurations and material grades to accommodate new production lines, capacity expansions and existing equipment retrofits for all sizes of steel mills.

Empowering Mills with Cost-Effective and Future-Ready Solutions

Faced with intensifying market competition, overcapacity pressure, rising operational costs and stricter environmental regulations, modern steel enterprises are focused on reducing unit production costs and improving product competitiveness. Extending refractory service life, minimizing unplanned downtime and lowering per-ton steel consumption have become core optimization strategies for steel plant management.

As one of the most frequently replaced and operationally critical refractory components in continuous casting, high-quality slide gate plates directly improve casting efficiency, stabilize slab quality and reduce overall operational expenditures. JI-STEEL avoids low-end homogenized manufacturing and focuses on high-performance, cost-effective refractory products that precisely match the industry’s current demands for efficiency improvement and cost reduction.
