Steel

Refractory products are essential to the steel industry, where extreme temperatures and harsh chemical environments demand highly durable and performance-oriented materials. Our steel refractory solutions are engineered for applications across blast furnaces, converters, ladles, tundishes, and more — ensuring operational stability, longer service life, and cost-effectiveness.

Electric ARC Furnace

Steel Ladle

The demand for various grades of steel with stringent specifications has increased considerably. Initially Steel Ladle was used only to transport steel from steel making units to casting bay. But now the steel ladle lining must withstand increasingly severe service conditions associated with secondary steel making in ladle. Secondary steel making is associated with longer holding time, higher liquid temperature and arc/chemical heating. Stirring with inert gases and degassing procedure, alloying and use of synthetic slag will also accelerate the wear. With the introduction of secondary refining and continuous casting, superior quality refractories are required for lining steel ladle.

REFSOL has wide range of refractories for steel ladle application. These refractories are pitch/resin-bonded dolomite, MgO-C, Alumina magnesia carbon, burnt alumina spinel, high alumina and fired magnesia chrome bricks.
Precast, preformed well block/seating block, castable/ramming masses for fixing well block/seating block, ladle bottom periphery and top tightening application are supplied by REFSOL.
High alumina and basic bricks are also offered by REFSOL for ladle back up application.

These products are manufactured from highest purity synthetic raw material & processed by using most modern manufacturing equipments. REFSOL products are consistently giving multiple heats & serving the needs of steel plant ladles, tundish etc.

Metal Refining Konverters, Argon-Oxygen Decarburisation (AOD):

Metal refining konverter is used for making stainless steel / Low Carbon Steel of various grades. Molten steel produced from induction furnace or electric arc furnace is poured into ladle & is subsequently poured into the converter with the help of E.O.T. crane. Before pouring the molten metal, some important parameters like its temperature & chemical composition are analyzed. Based on this analysis, molten steel is refined by the addition of required alloys & fluxes. Inert gases are also blown into the converter simultaneously.

Most AOD Linings were constructed with Magnesia Chrome refractories. Over time the AOD linings were switched to Fired Dolomite and Fired Magnesia Enriched Dolomite. Today, virtually all AOD Linings are now constructed with these refractories.

The switch to Fired Dolomite and Fired Magnesia Enriched Dolomite has reduced refractory cost and improved Stainless Steel quality. After AOD operators switched from Magnesia Chrome refractories to Dolomite refractories, AOD Lining designs have evolved over the years, as well. Now, many lining design use three grades of dolomite; resin bonded, fired dolomite and fired magnesia enriched dolomite. Linings are also zoned by thickness.
