Operators often see cracks and damage in ladle shrouds, long nozzles, and refractory parts. This happens because of a few main reasons: Knowing these reasons helps teams stop corrosion, breaks across the part, and chemical damage. This helps ladle shrouds last longer. Key Takeaways 1. Thermal Shock Temperature Changes When the temperature changes quickly, it puts stress […]
You can extend the life of your slide gate plate by selecting high-quality materials, employing effective operating methods, and performing regular maintenance.
When you choose ladle shroud from a China factory, there are both risks and opportunities. Some suppliers may not always provide good quality or reliable service.
In steel production, ladle nozzles are critical equipment for the regulation of molten steel flow from the ladle to the tundish in the case of continuous casting
A submerged entry nozzle (SEN) is an essential refractory component of the continuous steel casting process.
Introduction A ladle shroud, long nozzle, shrouding pipe, or pouring tube is a highly critical refractory component in continuous steel casting. It is a hermetically closed tube between the tundish and ladle so that molten steel will pass unbroken but be shielded from atmospheric contamination. Steel quality would otherwise be severely degraded by oxidation, turbulence,
1. Introduction One of the main refractory materials in the steel continuous casting process is a slide gate plate. It mainly aims at controlling the flow of molten steel out of the ladle or tundish in a controlled manner. Although it is a small component, it is very important in the efficiency of casting, safety,
Tundish stopper is an essential equipment in continuous steel casting that regulates molten steel flow from the tundish to the mold. Having the capability to provide accurate and stable control, it ensures consistent casting conditions, preserves product quality, and assists in the efficiency of the whole line.
In June 2022, the aluminum carbon FZ slagline ladle shroud used on site has a normal service life of 4h, extreme erosion (breakage) of 5h, and steel grades Q235 and Q235B Later, the steel company wanted to use a longer-life aluminum carbon slag line long nozzle, so it experimented with slag lines GZ and FN.
1.Steel Plant Introduction EAF, converter and refining system: The third steelmaking plant has 4 120t converters, with a steel output of about 110t, a smelting time of about 35min, and a steel output temperature of about 1620℃. The main steel grades smelted are: Q235A, Q235B, Q345D, SS400, SPHC, HPB235, CCS-A, etc. At present, about 130
