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%
