Split type breathable brick for ladle

Split ventilating bricks can adopt slit or impermeable ventilating brick cores, which are composed of ventilating cores, seat bricks and high-quality fire clay, all of which can be purchased separately. Due to the hot repair and replacement of the vent core, it is more flexible during use and can be used in various refining conditions. It can be applied to the bottom argon blowing process of LF, LF-VD, CAS-OB refining ladle and continuous casting ordinary ladle in steelmaking plants. . The high-quality fire clay used for the assembly of split air-permeable bricks is made of high-purity corundum as the main raw material and added with various additives. It can be used only by adding water on site. It has high refractoriness, easy adjustment, high bonding strength, Advantages of safe use and easy dissociation after use

main ingreadient:

Corundum spinelAl₂O₃：90-95% MgO：0-3.5% Cr₂O₃：0-3%

Features:

Breathable parts

The patented and unique formula of a variety of breathable cores has good thermal shock resistance, good erosion resistance, and good erosion resistance, which can meet the different needs of different customers.

Unique number

The brick core and seat brick of each ventilated brick has its own unique number, so that we can track the production and use situation, and provide a higher safety factor than the stricter and more rigorous quality management system.

Block design

The patented and unique design of the block can effectively prevent the block from breaking, and the safety factor is higher during refining!

Rigorous craftsmanship

The unique production process makes the venting core safer and effectively prevents air leakage from open welding.

Unique fire mud

Patented, the breathable fire clay specially developed for breathable bricks perfectly fits the characteristics of breathable bricks and gives you more peace of mind when using it.
