Anti-seepage type ladle bottom argon-blowing breathable brick: This product is made of high-purity raw materials and fired at high temperature. It has the advantages of thermal shock resistance, corrosion resistance, and impermeable steel. The product is composed of breathable seat bricks and impermeable breathable cores. The anti-seepage venting core is composed of an anti-seepage venting core element, a ventilating round table, and a peripheral castable. It is mainly supplied with argon through the anti-seepage element. It is used in steelmaking plants LF, LFVD, CAS-OB refined ladle The bottom argon blowing process of continuous casting ordinary ladle can be cleaned with less or no cleaning, with high blow-through rate, long life and good safety. Compared with slit-type air-permeable bricks, this product is safer, saves energy and reduces emissions, and can effectively reduce costs and increase efficiency for customers.

Split type ladle bottom argon-blowing ventilating brick: It can adopt slit type or impermeable ventilating brick core, which is composed of ventilating core, ventilating seat brick and ventilating brick 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 a variety of additives. It can be used only by adding water on site. It has high refractoriness, easy adjustment, high bonding strength, The advantages of safe use and easy dissociation after use can also be used to repair seat bricks, replace and install skateboards.
