Ladle Purging Plug

What is Ladle Purging Plug?

Ladle purge plug, also known as ladle permeable brick, is argon gas flow control equipment used in refinery ladle bottom. Ladle purge plug is adjustable in gas flow rate control and can be designed according to customer’s requirement. Made from super quality corundum materials, our ladle purge plugs have the characteristics of good thermal shock resistance, stable gas flow control ability, superior resistance against iron liquid. Therefore, ladle purging plugs from our factory have longer service life and popular in domestic market as well as oversea market.

Our purging plug is characterized by their high strength, good erosion resistance and corrosion resistance, high blowing rate and good safety. They are widely used for continuous casting ladles and refining ladles.

Ladle purging plug, also known as ladle permeable brick, has been widely used in bottom argon blowing refining ladles to control argon gas flow. Ladle Purge Plug or porous plug is a critical component in ladle bottom purging system. Apart from the purge plug life its reliability, gas flow rate quality of steel produced etc are evolving as the most important parameters to judge the purge plug quality.

What is the advantages of Ladle Purging Plug?

1. Good thermal shock property;
2. Anti-erosion, and impermeable;
3. Higher purging rate;
4. Longer service life;
5. Higher safety level;
6. Less pollution.

Ladle Porous Plug can be made of a slit type which is composed of a permeable core, a seat brick and a high quality fire mud, The main quality of the porous plug and Seat well block are chrome-corundum and corundum-spinel. Adopting tabular alumina, emery, chromium oxide green and magnesium alumina spinel as main raw materials, using cement as binder to produce directional slit porous plug, which has the advantages of structural stability, high air permeability, strong corrosion resistant and long service life etc. Due to the heat-replaceable replacement of the venting core, it is flexible in use and can be used in various refining conditions. It can be applied to the bottom argon blowing process of steel mill LF, LF-VD, CAS-OB refined ladle and continuous casting ordinary ladle.

Ladle Purging Plug Application:

Ladle purging plugs are mainly applied in refinery ladle bottom. Ladle Purging plug, being an important element in high temperature refining metallurgy, having been widely used in many industries, such as iron and steel, ferro alloy, non-ferrous metals etc.
