- Commodity name: Oxygen gun surrounding bricks
SA-AL series spinel refractories are characterized by high density, high hardness, and good thermal shock resistance. Their excellent resistance to melt erosion, corrosion, and drastic temperature changes has earned them consistent customer recognition.
Oxygen gun surrounding bricks are heat-resistant, durable, and designed to protect equipment during high-temperature oxygen cutting operations.
The working conditions around the oxygen lance bricks in the top-blown furnace with oxygen enrichment are harsh, requiring resistance to mechanical scouring by the molten bath, overheating and melting damage from oxidation reactions, and chemical corrosion by the molten bath. SA-AL series spinel refractories can be used according to the provided slag type and temperature.
SA-AL series spinel refractories have high density, high hardness, and good thermal shock resistance. Their excellent resistance to molten bath scouring, corrosion, and drastic temperature changes has earned consistent customer recognition.

SA-AL series spinel refractories are produced by pressing using a press, dried, and then sintered at high temperatures. After passing quality control, they are packaged using wooden pallets, corner protectors, and plastic steel straps.
refractory ramming mass is a high-performance, dense, and durable material designed for lining furnaces, kilns, and other high-temperature industrial equipment. It is composed of carefully selected refractory aggregates, high-purity alumina, and binding agents that provide excellent thermal stability, mechanical strength, and resistance to slag, chemical attack, and thermal shock. The material is specially formulated to be compacted or rammed into place, creating a seamless, monolithic lining that can withstand extreme temperatures and continuous thermal cycling. Refractory ramming mass offers superior insulation properties, reducing heat loss and improving energy efficiency in metallurgical, cement, glass, and steel production processes. Its dense structure ensures minimal porosity, preventing infiltration of molten metal, slag, or corrosive gases, which extends the service life of industrial equipment and minimizes maintenance requirements. The material can be customized in terms of composition, particle size, and bonding agents to meet the specific requirements of different high-temperature applications. Easy to install, reliable under extreme conditions, and highly durable, refractory ramming mass is an essential material for industries seeking long-term performance and operational safety in high-temperature environments.
