Ladle argon purge plugs refractory has been in the leading position at home and abroad for many years, and has developed a series of corundum, chromium corundum, low silicon chromium corundum and corundum spinel ventilation brick products. According to the requirements of users, we can design and manufacture various types of breathable bricks such as through pass, directional slit, directional labyrinth, ring slit and internal integral external assembly. The product ventilation flow is designed according to the requirements of users, with large adjustable range and high blowing rate. The main materials of the breathable brick are sintered magnesium, magnesium chromium, high aluminum and corundum.

Ladle argon purge plugs refractory is a kind of functional refractory material with high life, energy saving and emission reduction. It is made from high purity raw materials and has the advantages of high blowthrough rate, corrosion resistance, thermal shock resistance, safety, reliability and long life, etc. It is used for off-furnace refining of ferrous metals and smelting of non-ferrous metals.
The refractory material on the working surface of the breathable brick, especially the refractory material around the outlet, is directly in contact with high temperature molten steel and is affected by the continuous outflow of high temperature molten steel and cold airflow, resulting in a large temperature gradient.
Advantages of Ladle argon purge plugs:
It realizes the argon blowing process at the bottom of ladle breathable brick. The ladle breathable brick has the characteristics of high temperature resistance, corrosion resistance, thermal shock resistance, high temperature volume stability, high strength, good air permeability, stable operation, accurate shape size, less molten steel penetration and so on.
