In modern steelmaking, the Electric Arc Furnace (EAF) plays a central role in molten steel production. Its refractory lining—especially magnesia-carbon bricks—is critical to furnace efficiency and cost control. Due to extreme temperatures and harsh chemical exposure, understanding the erosion mechanisms of the EAF lining is essential for optimizing maintenance and ensuring…

In modern steelmaking, the choice of refractory materials plays a vital role in ensuring production efficiency and extending equipment service life. Magnesia carbon bricks, as one of the most important refractory materials for steelmaking applications, are widely used in electric arc furnaces (EAFs), ladles, and other high-temperature metallurgical equipment. So,…

Monolithic refractories, also known as unshaped or bulk refractories, are heat-resistant materials supplied in loose form and used without pre-firing or forming. Made from a mixture of aggregates, fine powders (additives), and binders, these materials offer excellent versatility and performance in high-temperature industrial applications such as steelmaking, non-ferrous metal production,…

In high-temperature industries such as steelmaking, cement, glass, and non-ferrous metallurgy, the performance of refractory materials plays a critical role in process efficiency and product quality. The performance of refractory materials is fundamentally determined by their chemical composition. Understanding the roles of main components, additives, and impurities is essential for selecting…

Charging bucket scrap preheating is a method that utilizes the high-temperature off-gas from electric arc furnaces (EAFs) to directly preheat scrap steel placed in the charging bucket. The main goal is to recover waste heat before the scrap enters the furnace, thereby saving energy and reducing production costs. Development and Application…

Scrap preheating refers to the process of heating steel scrap before it enters the electric arc furnace for melting. By utilizing various heat sources—especially waste heat from the furnace itself—scrap can be raised to a certain temperature prior to melting. This technique is increasingly adopted to reduce energy consumption, shorten…

The electromagnetic stirrer is mainly applied in ordinary power electric arc furnaces with capacities ranging from 10 to 50 tons. By stirring molten steel through non-contact magnetic forces, it significantly improves both melting efficiency and product quality. Structure and Working Principle of the Electromagnetic Stirrer An electromagnetic stirrer consists mainly…

In the steelmaking process of an Electric Arc Furnace (EAF), heat is generated by electric arcs between the electrodes and the steel or iron materials inside the furnace. This intense energy melts the scrap and heats the molten steel. However, the arc striking process causes sudden surges that impact the…
