Liquid steel is heated by electric arc to obtain new heat energy, which can not only add alloy and adjust composition during ladle refining, but also add slag, which is convenient for deep desulfurization and deoxidation of liquid steel. What’s more, the start pouring temperature of liquid steel required by continuous casting is guaranteed, which is conducive to the improvement of dry slab quality.
READ MOREIn the modern steel production process, the main functions of secondary refining are: (1) Undertake part of the original refining function of the primary furnace, complete part of the steelmaking reaction under the best thermodynamic and kinetic conditions, and improve the production capacity of the
READ MOREThe existing furnace covers of steel-making electric furnaces mostly adopt the structure of masonry refractory bricks. The disadvantages of the furnace covers of this structure are many brick cracks, poor overall performance, high energy consumption, short service life, and long maintenance.
