- Commodity name: Oxygen lance brick
SA-TP series spinel refractories are characterized by high density, high hardness, and good thermal shock resistance. They exhibit excellent durability against the severe scouring, chemical erosion, and high-temperature melting damage of molten materials.
Oxygen lance bricks for top-blown furnaces need to withstand the mechanical scouring of the melt, overheating and melting damage caused by oxidation reactions, and chemical corrosion of the melt. SA-TP series spinel refractories can be used according to the provided slag type and temperature.
SA-TP series spinel refractories have high density, high hardness, and good thermal shock resistance. They have excellent durability against the severe scouring, chemical corrosion, and high-temperature melting damage of the melt.
