Abstract

The invention discloses a device and a method for controlling superheat degree of molten steel in a continuous casting ladle or a tundish. The device comprises a temperature measuring device for measuring the temperature of the molten steel in the continuous casting ladle or the tundish, and a temperature control device for controlling the temperature of the molten steel in the continuous casting ladle or the tundish; the temperature control device comprises a scrap body material or a steel bar, a device for moving the scrap body material or the steel bar, and an electroslag heating device; the device for moving the scrap body material or the steel bar can insert the scrap body material or the first end of the steel bar into the internal part of a slag in the continuous casting ladle or the tundish, and can insert the scrap body material or the first end of the steel bar into the internal part of the molten steel; the slag is arranged above the molten steel and contacts the molten steel, and the electroslag heating device is electrically connected to the scrap body material or the steel bar, so that the current flows through the slag to heat the slag when the scrap body material or the first end of the steel bar is inserted into the internal part of the slag.

Description

technical field [0001] The invention belongs to the technical field of metallurgical continuous casting, and more specifically relates to a device and a method for controlling the superheat of molten steel in a continuous casting ladle or a tundish. Background technique [0002] The solidification of metals is an exothermic process. The degree of superheat marks the degree to which the liquid state of the metal exceeds the melting point temperature. The greater the degree of superheat, the more heat needs to be released for solidification of the metal, and the required solidification time increases under the same heat transfer. Therefore, the degree of superheat affects the solidification behavior of liquid metal materials. [0003] For example, when the degree of superheat is low, it can provide a large number of equiaxed crystal nuclei, generate equiaxed crystals, prevent the formation of columnar crystals in the early stage of solidification, and generate a large area o...
