Fixed Steel Ladle

This high-temperature and pressure-resistant Fixed Steel Ladle from Yuexin is a core piece of equipment for molten steel transfer and pouring in metallurgical casting workshops.  Custom-developed by Yuexin Machinery Manufacturing Co., Ltd. for molten steel handling applications, it features an integrated design of "high-strength shell + composite refractory lining + safety explosion protection," enabling the safe storage, transfer, and precise pouring of molten steel at temperatures of 1500-1650℃. It boasts a large carrying capacity and excellent thermal insulation performance. Compared to traditional steel ladles, it reduces heat dissipation rate by 30% and extends service life by 50%, making it a critical safety equipment for steel mills and foundries.

Product Parameter (Specification)

Product Feature

High-Temperature Load Safety: The ladle body is made of Q690 high-strength steel plate, rolled and welded, and inspected by non-destructive testing to ensure no welding defects. The shell tensile strength is ≥690MPa; equipped with explosion-proof pressure relief holes and temperature measuring devices to monitor the molten steel temperature in real time, avoiding safety hazards caused by high temperature and high pressure, conforming to GB/T 37400-2019 metallurgical safety standards.

Durable Composite Lining: The Fixed Steel Ladle adopts a "high-alumina brick + insulation layer + anti-seepage layer" composite structure. The working layer uses high-alumina refractory bricks with Al₂O₃ content ≥85%, improving corrosion resistance by 40%; a ceramic fiber insulation layer is used between the lining and the shell, effectively reducing the shell temperature, and controlling the outer wall temperature within 80℃.

Precise and Controllable Pouring: Equipped with manual/electric pouring mechanism, the pouring flow rate adjustment accuracy reaches ±5%; the ladle bottom is equipped with a permeable brick device, which can achieve uniform stirring of molten steel, reduce defects such as pores and slag inclusions during the pouring process, and improve casting quality. Operation and Maintenance Safety and Convenience: The ladle body features convenient inspection doors for easy inspection and replacement of the lining; the lifting trunnions are forged from 42CrMo alloy steel and equipped with rotating bearings, ensuring stable and vibration-free lifting; equipped with anti-splash guards to prevent splashing during molten steel transfer.

Application Scenarios

Fixed Steel Ladles are widely used in the steel metallurgy and casting industries, such as molten steel receiving and transfer in converter/electric furnace workshops, pouring of large castings in casting workshops, and post-refining transfer of molten steel in alloy steel production. They can accommodate the carrying requirements of different steel types, including carbon steel, alloy steel, and stainless steel, and are especially suitable for heavy casting production and continuous casting processes that require high pouring accuracy and safety, providing core assurance for safe and efficient production in metallurgy and casting.
