JUCOS Refractories > Shaped Refractories > Porous plug & Seat well block
Product Details

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.
