Guoliang company owns three wholly-owned subsidiaries and one branch. It is a high-tech enterprise specializing in the integrated solution of refractories for high-temperature industry, providing customers with general contracting services and refractory products.
A porous plug is a key refractory component used in steel ladle refining systems. It injects argon gas into molten steel through controlled permeability, creating strong stirring inside the ladle.
The argon gas is blown into the steel ladle through the porous plug, and the molten steel is strongly stirred. The main function and purpose are: uniform molten steel composition and temperature, and promote the collision floating of inclusions.

Tell us your ladle size, refining process, and operating conditions. Our engineers will recommend the suitable porous plug solution.
A porous plug for steel ladle is widely used in secondary metallurgy and molten steel refining processes. By injecting argon gas into molten steel, the ladle porous plug helps improve steel cleanliness, temperature consistency, and chemical composition uniformity.
Our refractory porous plug solutions are suitable for various steelmaking applications, including:
The porous plug for steel ladle refining is used in ladle furnaces (LF) to provide stable argon stirring, promoting inclusion flotation and improving molten steel quality.
In secondary refining processes, the argon purging plug ensures efficient gas distribution, helping reduce impurities and improve metallurgical performance.
The porous refractory plug is widely applied in stainless steel refining where precise temperature and composition control are required.
For alloy steel production, the ladle purging plug improves mixing efficiency and supports better alloy distribution in molten steel.
A high-performance gas purging porous plug helps maintain stable molten steel conditions before continuous casting, reducing defects and improving final product quality.
A porous plug is used to inject argon gas into molten steel for stirring, improving steel cleanliness and temperature consistency.
Argon gas is commonly used because it prevents oxidation during steel refining.
Porous plugs are typically made of alumina, magnesia, chrome-based refractory materials with excellent thermal resistance.
The service life depends on steel grade, refining conditions, blowing rate, and slag chemistry.
Yes, custom dimensions and refractory formulations are available based on ladle size and refining conditions.
Both are used for gas stirring, but design structure, permeability, and application conditions may vary.
