Problems solved by technology

Although industrial experimental research can more intuitively reflect the impression of operating process parameters on the desulfurization effect, but limited by industrial production conditions, the process factors that affect the desulfurization rate, desulfurization efficiency and stirring time of molten iron, such as the type of desulfurizer, molten iron, etc. The scope of top slag composition, molten iron temperature, initial sulfur content of molten iron and initial oxygen content of molten iron cannot be greatly expanded
At the same time, it is difficult to study the impact of some cutting-edge technologies that can improve the desulfurization efficiency of molten iron, such as wall cladding baffles, on the improvement of desulfurization efficiency.
Industrial experiments also have disadvantages such as high cost, long cycle, and difficulty in process stability control.

Description

technical field [0001] The invention relates to the desulfurization pretreatment technology of molten iron, and more specifically relates to a thermal state test system for stirring desulfurization of molten iron. Background technique [0002] In recent years, with the continuous improvement of users' requirements for steel quality, especially high-quality pipeline steel, container steel, acid-resistant steel, etc., the S content in steel is required to be less than 0.005%, or even below 0.001% [1]. Therefore, the hot metal desulfurization pretreatment process is increasingly important in iron and steel smelting. Hot metal pre-desulfurization plays an important role in improving steel quality, optimizing steel production process, saving energy and reducing consumption, etc. It has developed into an indispensable link in iron and steel metallurgy. Among the many pre-desulfurization methods of molten iron, the KR (Kanbara reactor) mechanical stirring method has been widely ad...
