Abstract

The invention discloses an electrode for applying pulse current to a continuous casting tundish. The electrode is characterized by comprising a cone frustum shaped fireproof material (2) and an electrode distribution plate (3) embedded into the fireproof material (2); a plurality of rod-like small electrodes (4) are vertically distributed on the surface of the electrode distribution plate (3); the rod-like small electrodes (4) pass through the cone frustum shaped fireproof material (2), and the ends of the rod-like small electrodes (4) are naked on the surface of the cone frustum shaped fireproof material (2) and connected with molten steel; the bottom end of the electrode distribution plate (3) is provided with a pulse current connecting end (1); and the pulse current connecting end (1) passes out of the bottom end face of the cone frustum shaped fireproof material (2) and is connected with a pulse power supply. The electrode has the advantages of strong high-temperature oxidation resistance and molten steel melting resistance, long service life, good conductivity, simple and feasible operation in a pulse processing process, safety and reliability.

Description

technical field [0001] The invention belongs to a technique for applying pulse current to a continuous casting tundish in the field of steelmaking, in particular to an electrode for applying pulse current to a continuous casting tundish. Background technique [0002] Improving the strength, toughness, ductility, processing performance and service life of steel is one of the important research topics of the steel industry in the 21st century. Changing the metallographic structure and refining the grain size is one of the methods. It can be achieved by increasing the content of specific alloying elements in the steel, or it can be achieved by controlled rolling and controlled cooling and equal-diameter angular extrusion cold deformation technology. [0003] Electric pulse refinement of solidified metal structure is a new technology in the field of metal structure refinement. Electric pulse refinement of continuous casting slab solidification structure is mainly to control th...
