The invention discloses a device and method for measuring the crystallization starting temperature of high-temperature slag based on conductivity, and belongs to the technical field of metallurgical slag performance detection. The device is mainly composed of a conductivity testing system, a heating system, a lifting system, an atmosphere control system and a temperature control system, and is used for measuring the crystallization starting temperature of the high-temperature slag, particularly, a precise LCR digital bridge and a molybdenum rod are used, a four-probe method is adopted for recording the conductivity value in the continuous cooling process of the slag in real time, and finally the crystallization starting temperature of the slag is determined. According to the technical scheme, the temperature in the furnace, the bottom end of the molybdenum rod and the depth of the molybdenum rod inserted into the high-temperature slag can be accurately controlled, the resistance of the molybdenum rod and a wire and the influence of the polarization effect on the high-temperature slag are eliminated, and the conductivity value in the slag cooling process is accurately measured; and thus, the crystallization starting temperature of the slag is obtained based on the conductivity-temperature curve.
Description
technical field [0001] The invention belongs to the technical field of metallurgical slag performance detection, and more specifically relates to a device and method for measuring the crystallization temperature of slag based on electrical conductivity. Background technique [0002] In the process of iron and steel smelting, slag plays a vital role in separating or absorbing inclusions, protecting metals from environmental pollution, and reducing metal heat loss. steel” general consensus. Among them, mold slag, as a functional material that guarantees continuous casting production and excellent quality of slab, has the most stringent and demanding performance requirements, and needs to comply with the continuous update of steel variety research and development and the continuous improvement of quality requirements. Add the mold slag on the molten steel surface of the mold, flow into the gap between the billet and the wall of the mold after melting, solidify on the side of t...
