The converter slag retainer is a device used in the converter steelmaking process. Its primary function is to block slag during tapping, preventing it from entering the ladle and thus improving molten steel quality. A converter slag retainer typically consists of a slide mechanism, a drive device, and a detection device.

1.Slide mechanism: This is the core component of the converter slag retainer and typically consists of a slide, a slideway, and a slider. The slide mechanism opens and closes during tapping to retain slag.

2.Drive device: This is the key component controlling the opening and closing of the slide mechanism and typically utilizes hydraulic or pneumatic actuation. The drive device precisely controls the opening and closing time and speed of the slide according to process requirements.

3.Detection device: This is used to monitor the formation and flow of slag, as well as the flow of molten steel. The detection device typically includes infrared detection devices and cameras, enabling real-time monitoring of the flow of slag and molten steel, providing data support for precise control of the slag retainer.

The converter slag retainer plays a crucial role in the converter steelmaking process. It effectively prevents slag from entering the ladle, reducing inclusions in the molten steel and improving its purity and quality. Furthermore, it reduces contamination and oxidation of the molten steel in the slag, further improving smelting efficiency and yield.

In practical applications, the design and control accuracy of the converter slag retainer significantly impact the steelmaking process. Therefore, the design and manufacture of the converter slag retainer must fully consider process requirements, equipment performance, and operational maintenance to ensure stable and reliable operation. Furthermore, the use and maintenance of the converter slag retainer must comply with relevant regulations and operating requirements to ensure long-term stable operation and extend its service life.
