Magnesia-carbon bricks are refractory materials made from high-melting-point basic magnesium oxide (melting point 2800°C) and high-melting-point carbon materials that are resistant to slag wetting. Various non-oxide additives are incorporated, and the mixture is bonded using a carbon-based binder. Magnesia-carbon bricks are primarily used for the linings of converters, AC arc furnaces, and DC arc furnaces,

Basic refractory castables are granular and powdered materials formulated from refractory aggregates—primarily magnesia—along with binders and additives. Based on their composition, they can be classified into types such as magnesia, magnesia-alumina, magnesia-chrome, magnesia-silica, and spinel castables. What are the characteristics and applications of these basic refractory castables? Here, a manufacturer of refractory castables outlines their

Refractory castables, also known as unshaped refractories, are granular and powdered materials made from refractory substances, combined with a specific amount of binder and water. They possess high fluidity, making them suitable for application via casting; they are unshaped refractories that harden without the need for heating. They are typically formed on-site through casting, vibration,

Magnesium-carbon bricks for oxidation prevention Magnesia-carbon bricks are composite materials consisting of magnesia and carbon. Graphite plays a key role in inhibiting slag penetration and providing erosion resistance, while resin-bonded carbon provides the structural strength of the bricks. However, the greatest weakness of both resin-bonded carbon and graphite is their susceptibility to oxidation. Therefore, since

The application of top-bottom oxygen blowing technology and slag quenching and furnace protection technology has expanded the range of products produced in the converter and significantly improved quality and production efficiency. Tapping, as the final step in the converter steelmaking process, has become a key factor influencing the quality, output, and product variety of steelmaking.
