Iron & Steel

Today, steel is produced by two main industrial production methods. The integrated route utilises iron ore and coal in a blast furnace to produce molten iron which is subsequently transferred to the basic oxygen furnace (BOF) in which it is converted to steel. The second steelmaking route melts scrap steel and/or sponge iron from direct reduction in an electric arc furnace (EAF). KONREF provides high grade and reliable refractory materials to steel producers for their indispensible needs in the steel production.

S Metal refractories is a full-range refractory manufacturer for Electric Arc Furnace (EAF), Basic Oxygen Furnace (BOF), TUNDISH, Induction Furnaces, TORPEDO Ladle, and Treatment Ladle.

Electric Arc Furnace

Electric Arc Furnace (EAF) is a steel making furnace, in which steel scrap is heated and melted by heat of electric arcs between the furnace electrodes and the metal bath.

Refractory linings of EAFs are made generally of fired magnesia and resin-bonded magnesia-carbon bricks. Fused magnesia grains and flake graphite are used as raw materials.

Basic Oxygen Furnace Converter

Basic oxygen steelmaking (BOS, BOP, BOF, or OSM), is a method of primary steelmaking in which carbon-rich molten pig iron is made into steel. Blowing oxygen through molten pig iron lowers the carbon content of the alloy and changes it into low-carbon steel. The process is known as basic because fluxes of burnt lime or dolomite, which are chemical bases, are added to promote the removal of impurities and protect the lining of the converter.

Steel Ladle

The carrying out of metallurgical reactions in the ladle is a common practice in practically all steelmaking shops, because it is cost-efficient to operate the primary furnace as a high-speed melter and to adjust the final chemical composition and temperature of the steel after tapping.
