Iron ore is the key raw material for making iron and steel. However, it cannot be used in its unprocessed state. Sinter production is a thermal process that converts the mixture of agglomeration iron ore fines, coke, and fluxes into a sinter—the primary feed material of suitable composition and granularity for the induction blast furnace.
The key processes during sinter production involve homogenizing high throughputs of raw materials, loading, and heating the sinter mix onto the sinter strand, feeding the crystallized sinter cake into a crash deck sizing and feeding the hot screens, cooler and then further cold screening of the sinter before it is sent to the Blast Furnace.
Wear is omnipresent in the sinter production process, from sinter mixture preparation to the recycling of fines and sinter transport to the blast furnace. Wear occurs mostly due to abrasion/impact during loading, mixing, material transfer, and thermal stresses during heating. It involves components such as internal linings of bins, sinter mix feed chutes, hoppers, hearth layer, crash decks, hot and cold screen feed chutes, conveyor transfers, dust collection and scrubber.
Wear Resistance Sinter Production
Wear resistant linings safeguard these critical components against wear and abrasion. A proper selection of wear resistant linings can significantly improve the service life of the sinter plant while ensuring a high purity sinter feed with minimum contamination due to wear. Wear resistant linings are a cost effective solution to improve the overall efficiency of the sinter production, besides extending the equipment lifetime and achieving maximum operation levels.
Thanks to their excellent wear and corrosion resistance, superior thermal shock resistance, low thermal expansion, high hardness, and ability to withstand harsh service environments, Saint Gobain’s extensive range of ceramic based wear resistant linings are a proven, cost effective solution for routine applications in sinter production. For these advantages, refractory materials outperform conventional materials like abrasion resistant steels, rubbers, and plastics.
Saint Gobain’s high performance wear resistant linings are based mostly on aluminum oxides and silicon carbides. They are pre-engineered for efficiently reducing wear in severely demanding applications. Some state-of-the-art economic solutions spanning a versatile range of product specific applications include:
