Description
Technical Field
[0001] The utility model relates to a sampling device, in particular to a device capable of sampling the steel slag on the surface of the molten steel inside the ladle, belonging to the technical field of molten slag sampling equipment inside the ladle. Background Technique
[0002] During the secondary refining process of molten steel, the physical and chemical indexes of the top slag in the ladle are directly related to the quality of molten steel. A suitable top slag system in the ladle can quickly carry out diffusion deoxidation on the molten steel and adsorb inclusions in the molten steel. At the same time, it can isolate the molten steel from contact with air, avoid secondary oxidation of molten steel, and play a role in heat preservation of molten steel. During the slag-making process of secondary refining of molten steel, it is necessary to sample the initial slag and the top slag after adding slag-making agents and deoxidizers. By observing manually to determine on-site conditions such as the viscosity and color of the top slag to judge whether the top slag meets the target requirements. During the adjustment process of the ladle top slag, it is also necessary to sample the top slag for chemical analysis to judge whether the slag system is reasonable. At present, the main method of taking slag samples is to insert a metal tube by hand into the ladle to dip the slag sample. This sampling method is prone to cause the slag sample rod to stick and wrap molten steel, and the cold steel will affect the accuracy of the chemical component analysis of the slag sample. At the same time, the labor intensity of manual sampling is relatively large, and it is highly dangerous for workers to operate near the high-temperature ladle.
