Abstract

The invention belongs to the field of high-temperature metallurgy experiments and relates to a device and method for a slag metal high-temperature reaction experiment in the metallurgical process. Theexperimental device comprises a supporting device, a hanging device, a magnesia crucible, a material adding molybdenum hook and L-shaped iron pieces, wherein the supporting device is composed of a graphite outer sleeve crucible and a graphite supporting rack, the graphite supporting rack is movably fixed on the graphite outer sleeve crucible, the graphite outer sleeve crucible is internally provided with the magnesia crucible, a pi-shaped hook is provided with a sunk molybdenum wire which is horizontally arranged on the graphite supporting rack and passes the circle center of the graphite supporting rack, one other V-shaped molybdenum wire is connected with the sunk position of the horizontal molybdenum wire in a lapped manner, and the bottom faces of the L-shaped iron pieces are larger than a centre hole and are arranged inside the graphite crucible for blocking the centre hole in the bottom of the graphite crucible. By means of the device for the slag metal high-temperature reactionexperiment in the metallurgical process, multiple sampling can be performed after steel materials are melted and before slag materials are added, after slag metals react for a certain time and aftera deoxidizing agent is added in according to requirements in the high-temperature experiment, and the experiment is performed more conveniently and efficiently.

Description

technical field [0001] The invention belongs to the field of high-temperature metallurgical experiments, and relates to a device and method for experimental research on slag-gold high-temperature reaction in metallurgical processes. Background technique [0002] In recent years, with the advancement of domestic steelmaking technology and the continuous improvement of the research and development level of high-quality steel, the requirements for the control of non-metallic inclusions in steel have become more and more stringent. The production of clean steel with high efficiency and low cost is an important technology in the field of iron and steel at home and abroad, and the control of non-metallic inclusions in steel is the key to the production of clean steel, and it is also a research hotspot in the field of iron and steel metallurgy. The non-metallic inclusions in the steel destroy the continuity of the steel matrix, and have adverse effects on the ductility, toughness, ...
