Abstract

A growing requirement to make low or ultra-low carbon steel has resulted in strong demand for lower carbon content in the MgO-C refractory lining materials of metallurgical vessels. Incorporation of carbon nanostructure materials is expected to reduce the total carbon content of refractory bricks due to their very high specific surface area compared to other carbon precursor materials. It will also help to significantly enhance both the corrosion and thermo-mechanical behaviour of refractories. Different compositions were designed to evaluate the effect of using industrial grade functionalised multi-walled carbon nanotube (F-MWCNT) in MgO-C refractory. Samples containing an appropriate combination of graphite and F-MWCNT produced the most impressive results. Based on the study, brick was developed for a panel trial in a 300-t ladle of BSL (Bokaro Steel Plant) at SAIL (Steel Authority of India Limited). The average erosion rate of carbon nanostructure-containing MgO-C brick refractory was observed to be about 28 mass-% less than that of conventional MgO-C bricks.
