Silicon carbide hearth brick: Special anti-corrosion brick for reaction chamber hearth, resists 500-600℃ high temperature and strong acid/alkali corrosion.

Product Introduction of Potassium Sulfate Kiln Hearth Bricks

The potassium sulfate kiln hearth brick is a core special refractory component for the reactor in Mannheim-process potassium sulfate production lines. It is specially designed to adapt to the high-temperature and strong-corrosion working conditions during potassium sulfate production, serving as a critical material to ensure long-term stable operation of the kiln.

Core Performance Advantages

Ultra-long corrosion-resistant service life‌: Manufactured with improved new materials and innovative processes, it achieves no acid leakage for more than 6 years, significantly reducing kiln maintenance frequency and operation & maintenance costs. Compared with traditional refractory bricks, it cuts equipment maintenance expenses by 60% and effectively extends the annual effective operation time of the production line.

Excellent performance adapted to working conditions‌: The formula is optimized for the high-temperature environment and acidic material scouring inside the potassium sulfate reactor. It balances high mechanical strength and outstanding thermal conductivity, enabling more uniform heating of materials in the furnace, ensuring complete reaction of raw materials during production, and helping the production line increase the unit output by about 20%.

Customized production capability‌: It supports customizing special-shaped specifications according to the structural dimensions of different kilns, which fits the masonry requirements of all kinds of new and old Mannheim potassium sulfate reactors. It can be directly installed and used without additional adjustment to the furnace body structure.

Supporting Services and Application Scenarios

This type of hearth brick is widely used in potassium sulfate production projects in China and overseas countries including the Philippines, Indonesia, Egypt, India, Jordan, etc. We can synchronously provide overall kiln masonry construction and old kiln transformation & upgrading services. When matched with the same system of silicon carbide dome bricks and dedicated thermal insulation systems, it can further reduce production energy consumption by 20% while making the exhaust emissions meet environmental protection standards.
