FAQ
Are refractories from Saint-Gobain Performance Ceramics & Refractories suitable for use in the production of hydrochloric acid and salt cake?
Sulfate fertilizers are typically processed in Mannheim furnaces. The salt feeder can be lined with mullite bricks (Mullfrax® 202 HF bricks), while the combustion chamber can be lined with Carbofrax® M silicate bonded SiC tiles in the muffle dome in order to ensure effective heat transfer onto the salt mix underneath.
Carbofrax® domes function as muffles with excellent thermal conductivity and high-temperature chemical resistance, enabling long operational runs.
Refrax® 20 nitride bonded SiC bricks are ideally suited for use in the reaction tank, with cast Refrax® cast nitride bonded SiC providing outstanding chemical resistance to the spout blocks and rabble blades.
Can Saint-Gobain Performance Ceramics & Refractories provide flexible shape designs for different reactors?
Saint-Gobain Performance Ceramics & Refractories‘ high purity alumina and mullite dense insulating bricks, and its oxide bonded silicon carbide products are ideal for use in the fertilizer industry.
Saint-Gobain Performance Ceramics & Refractories works in partnership with major engineering companies in reactor design; leveraging this cooperation to provide materials with exceptional chemical, wear and thermal shock resistance, ultimately contributing to longer equipment service lives.
