Silicon Carbide Ceramics in Metallurgy Industry

Silicon carbide (SiC) ceramics feature outstanding high-temperature resistance, excellent molten slag & metal corrosion resistance, high structural strength, anti-erosion wear performance, superior thermal shock stability and high thermal conductivity. Perfectly suited for the harsh working conditions of the metallurgy industry — high temperature, heavy corrosion, strong scouring and continuous production. It has become an upgraded core refractory and structural material for iron & steel smelting, non-ferrous metallurgy, high-temperature kilns and metal casting.

In iron and steel production, silicon nitride bonded SiC products are widely used in blast furnace linings, furnace belly and ceramic cup liners. They effectively resist erosion from molten iron, slag and high-temperature flue gas, greatly extending furnace service life and reducing maintenance downtime.

SiC filters and flow control parts for continuous casting efficiently remove inclusions from molten steel, improving metal purity and finished product quality.

For non-ferrous smelting, SiC ceramics are applied in aluminum electrolytic cell linings, furnace kiln furniture, high-temperature slide rails, heat insulation boards, melting crucibles and thermocouple protection tubes. They withstand corrosion from molten metal and cryolite, avoiding deformation and metal contamination at extreme temperatures, cutting energy consumption and optimizing production efficiency.

High-temperature heat exchange and waste heat recovery components made of SiC adapt to ultra-high temperature flue gas environments. With high heat conductivity, they support energy saving, carbon reduction and waste heat recycling.

Custom wear-resistant and anti-corrosion structural parts maintain stable performance under drastic temperature changes, lowering parts replacement costs and ensuring long-term, stable operation for metallurgical production lines.
