The SR-TQ series of straight-through narrow-slit air-permeable bricks made of plate-shaped corundum and high-purity spinel as the main raw materials and MAS matrix optimization system have the characteristics of stable structure, wide range of air permeability, easy adjustment of gas flow, high blowing rate, anti-scouring, anti-erosion and long service life. When used on small and medium-sized continuous casting ladles, the service life is synchronized with the ladle lining. When used on refining ladles, the service life can reach more than 30 times. It can be used in two forms: integral and split according to the site conditions.

      SR-WS series ladle nozzle bricks are made of high-purity, high-density raw materials and MAS matrix optimization system design. They have the advantages of stable structure, anti-scouring, corrosion resistance, good thermal shock stability and long service life.
