SUMMARY:Low phenol binding system for high performance environmental-friendly taphole clay
DESCRIPTION:The new climate and environmental challenges have made the iron making industry move towards a cleaner production and therefore to a greener refractories consumption. The blast furnace being the main vessel in the iron making process, its tapping mainly relies on the quality of the Taphole Clay (THC). For a long time, coal tar bonded Taphole Clays were used for their easy injection and good adhesion to taphole walls but their high toxicity led to the use of phenolic resins. Despite their lower toxicity level, these resins are recently presenting some health issues for the plant workers especially with their free-phenol content which sometimes may be present up to nearly 10% in the resins. In this study, two different resin binding systems: a conventional phenolic resin and a low free-phenol resin were examined and compared. On a first hand, the effects of these binding systems on general plastic behavior of the products were analyzed and also correlated to their physical and mechanical properties. A comprehensive understanding of the Taphole’s severe operating conditions such as high temperature, high pressure, corrosion by slag and molten pig iron is required. Therefore, the injectability of the studied samples was investigated at high temperature in order to characterize the setting of the material, the cracks formation and the outlet of volatiles during the plugging mechanism of the Taphole Clay in the blast furnace. A chemical analysis of the Polycyclic Aromatic Hydrocarbon (PAH) present in the samples was also performed.
