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.
High-performance purging plug for steel ladle refining, designed for stable argon blowing, excellent permeability, and long service life in molten steel refining applications.
Our refractory purging plug is widely used in ladle furnaces (LF), secondary metallurgy, and continuous casting systems to improve molten steel cleanliness, temperature uniformity, and alloy mixing efficiency.
During use of purging plug, argon gas is blown into the ladle through the purging 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.

TECHNICAL SPECIFICATIONS
A purging plug is an important steel ladle refractory component installed at the bottom of a steel ladle to inject argon gas into molten steel. The steel ladle purging plug enables controlled gas stirring, helping optimize metallurgical performance during secondary refining.
Through stable gas permeability, the argon purging plug improves:
Guoliang ladle purging plug solutions are engineered for harsh steelmaking environments with superior thermal shock resistance and erosion resistance.

Our purging plug refractory products are widely used in various steelmaking and metallurgy applications.
The purging plug for steel ladle is commonly used in LF furnaces for argon stirring, improving steel cleanliness and temperature consistency.
The ladle purging plug supports secondary refining by promoting inclusion flotation and reducing impurities in molten steel.
The argon purging plug is ideal for stainless steel refining processes requiring precise composition control.
The refractory plug for ladle refining improves alloy mixing and enhances steel quality consistency.
Our steel ladle purging plug helps stabilize molten steel conditions before casting, reducing defects and improving product quality.
With extensive experience in steel ladle refractory solutions, we provide reliable refractory purging plug products for global steel plants and metallurgy industries.
A purging plug injects argon gas into molten steel to improve stirring, temperature consistency, and steel cleanliness during refining.
Most steel ladle purging plugs use argon gas because it prevents oxidation and improves refining efficiency.
Our refractory purging plug products are manufactured using high-quality alumina, magnesia, and other refractory materials with excellent thermal resistance.
A porous plug refers to the gas-permeable structure, while a purging plug emphasizes its gas injection function in steel ladle refining. In many steelmaking applications, the terms are used interchangeably.
