Ladle Refractory Porous Purging Plug for Steelmaking

Purging Plug For Ladle bottom argon blowing

In steelmaking today, gas blowing in a ladle is indispensable for improvement of steel quality and for continuous casting.
In this field, we dominate the market with our Porous Plugs and Slot(Slit) Plugs.

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.

-Slot Plug(slit plug)
Slot plug is the most common structure in purging plug.
The gas channel could be designed and customized according to actual on-site using conditions, including refining steel grade, refining workmanship, ladle capacity, temperature, hydrostatic pressure of liquid steel etc.
This can achieve the best blowing effect for purging plugs, ensure the longest service life, safety, stability and best air
permeability.

-Porous plug
Porous plug has better porosity and permeability.
Production technology is adding carbon-containing compound into mixture, since carbon-containing compound can burn out without residue at low temperature, so we adopt low temperature burning out intermediate materials to get the initial porosity.
In porous type plug, inside distributes interpenetrating gas channels in different sizes.
When blowing stop, the steel and slag from ladle will infiltrate into the deep areas of the plug, to form a secure layer on working surface.

-Hybrid Plug
Secondary refining technology is the most important part in steelmaking process.
It can adjust the steel alloy type and liquid temperature.
Purging plug and block is the key functional component to make this process carried out.

As the ladle tends to develop in larger scale, the melting temperature and time have been improved significantly, which makes the using environment for refractory materials more and more strict. Therefore, it is necessary to further improve the performance of purging plugs and blocks to meet the increasing demands in current steelmaking technology.

-Overall breathable brick:
