carbon transfer from magnesia-graphite ladle refractories to ultra

Magnesia Bricks

Magnesia-Carbon bricks are un-fired refractory products. Mag-carbon products are designed with improved corrosion and slag resistance through the addition of graphite. When a magnesia-carbon brick is bonded with an organic resin, it is also known as resin-bonded magnesia-carbon brick.

Comprehensive Solution of Refractory for Steel ladle

Carbon-free refractories are high quality, environmental friendly and energy-saving materials developed as ladle working lining for low-carbon and ultra-low carbon steel production. Those refractories are characterized with high strength, high erosion resistance, high

ent in carbon-containing refractories were also studied by Yamaguchi5,6 and Poirier and Rigaud.7 The effect of MgO grain size and graphite content on the physical and chemical properties of MgO–C substances has also been extensively in-vestigated.8–11

Refractories and Classification of Refractories – IspatGuru

The common examples of these refractories materials are carbon graphite (most inert), chromite refractories, and alumina refractories. Out of these graphite is the least reactive and is extensively used in metallurgical furnaces where the process of oxidation can be controlled.

Carbon transfer from magnesia

Ultra-low carbon steels are utilized in processes which require maximum ductility. Increases in interstitial carbon lower the ductility of steel; therefore, it is important to examine possible sources of carbon. The refractory ladle lining is one such source. Ladle refractories often contain graphite for its desirable thermal shock and slag corrosion resistance. This graphite is a possible

(PDF) Mechanism for Carbon Transfer From Magnesia

Franken et al. found that the spread of carbon pickup from carbon-containing refractories was too great and unpredictable for use in ULC steels, which forced a change to carbon-free refractories. 4 Tassot et al. switched from 3 wt.% C dolomite bricks in the ladle

Development of Improved Quality Magnesia Carbon Brick

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

Carbon plays an important role in improving the thermal shock resistance and the slag corrosion resistance of the MgO-C refractory, due to its low thermal expansion coefficient and its poor wettability with slag [].However, carbon is susceptible to oxidation [], particularly in high temperatures, which is classified into direct (Equation (1)) and indirect oxidation (Equation (2)).
