Problems solved by technology

Physical simulation uses the flow similarity criterion. Generally, liquid steel at room temperature is used to simulate molten steel, and paraffin or other materials are used to simulate inclusions. This method can visually see the movement trajectory of inclusions, but this method is not suitable for simulating particle size. The movement of inclusions at the micron level, and a considerable part of the inclusions in molten steel have particle sizes at the micron level

Description

technical field [0001] The invention belongs to the field of metallurgical industry, and in particular relates to a simulation method and system for the movement track of solid inclusions in molten steel. Background technique [0002] Inclusions in molten steel can be divided into foreign inclusions and endogenous inclusions according to their sources. Foreign inclusions are caused by refractory materials or slag remaining in the steel during the smelting process. Endogenous inclusions are caused by deoxidation of molten steel. A large number of studies have shown that inclusions in steel have great harm to the quality of steel. On the other hand, during the pouring process of molten steel, inclusions will deposit on the refractory wall and cause nodules, which will affect the smooth production. The removal of inclusions generally utilizes the good fluidity of molten steel and the density difference between inclusions and molten steel to remove inclusions. Therefore, exp...
