How does the ladle slide gate system ensure the quality of molten steel and production safety?

Unstable molten steel flow and breakout are two major safety hazards in the continuous casting process. Precise flow control and the elimination of breakout are crucial for ensuring molten steel quality and production safety. Rongsheng Refractory offers safe, reliable, and precisely controlled ladle slide solutions to ensure production safety and product quality. Our ladle slide systems have been successfully implemented and widely recognized by our customers, serving numerous steel mills worldwide.

The ladle slide system can accurately control the flow

The stability of molten steel flow directly impacts the quality of ingots, and unstable flow can easily lead to various casting defects. Zhongtian Materials utilizes an advanced integrated hydraulic/electric drive system with a response time of less than 0.5 seconds and an aperture adjustment accuracy of ±0.3 mm. This ensures stable molten steel flow, effectively reducing casting fluctuations and reducing molten steel flow fluctuations by approximately 50%, significantly improving molten steel purity and ingot quality.

A high-precision aperture control system further ensures the stability of molten steel flow. A slide system with automatic control is recommended, which automatically adjusts the slide opening based on the molten steel level or casting speed for precise flow control.

Ezen kívül, sensors such as flow meters and level gauges enable real-time monitoring of molten steel flow and feed data back to the control system, implementing closed-loop control. Deviations can be detected and corrected promptly, ensuring a continuous, stable, and safe casting process.

Ladle slide to prevent molten steel from leaking

Molten steel leakage is a serious production safety hazard, potentially causing not only equipment damage but also personal injury. Zhongtian Materials addresses this issue with a triple-seal design (graphite + metal + kerámia szál) to effectively prevent molten steel leakage and fully guarantee production safety.

First Seal: The graphite layer

Offering excellent high-temperature stability and self-lubricating properties, it maintains its shape even in extreme temperatures, effectively preventing molten steel leakage.

Second Seal: The metal layer

Offering high strength and excellent wear resistance, it further enhances the sealing effect while withstanding external pressure, preventing molten steel from penetrating.

Third Seal: The ceramic fiber layer

Offering excellent high-temperature resistance and sealing performance, it provides an additional protective barrier even if the first two layers fail, ensuring system safety and reliability.

Through this multi-layer composite sealing structure, Zhongtian Materials significantly improves the safety and stability of the ladle sliding gate system, providing a solid foundation for the continuous molten steel casting process.
