感应中频电炉熔炼特点
[来源:www.zhongpinshebei.com] [作者:aywl] [日期:17-06-26]
根据感应原理,感应电炉的感应线圈和坩埚中的金属液是两个同心异体。感应线圈相当于一次绕组,金属液是二次绕组。感应线圈中的电流和金属液中的感应电流,两者的方向在某一瞬间是相反的。因此感应线圈和金属液间将产生两个相互排斥的电磁力。在电磁力的作用下,金域液由坩埚四周被推向中心。产生“超肤效应”(集肤效应)和电磁搅拌。 According to the induction principle, the inductor coil of induction furnace and the metal liquid in the crucible are two concentric bodies. The induction coil is equivalent to one winding and the metal liquid is secondary winding. The current in the induction coil and the induction current in the metal liquid are reversed in one moment. So the induction coil and the metal liquid will produce two electromagnetic forces that repel each other. Under the action of electromagnetism, the gold domain fluid is pushed to the center around the crucible. It produces "skin effect" (skin effect) and electromagnetic stirring.   (1)超肤效应:感应电炉的感应圈在金属内部产生的磁通分布是不均匀的,越靠近坩埚壁磁通密度越大,而在坩埚中心磁通密度越小。 : (1) the skin effect of induction furnace inside the metal induction coil, the magnetic flux distribution is uneven, moving closer to the magnetic flux density, the greater the crucible wall and the smaller the magnetic flux density in the center of the crucible.   (2)电磁搅拌现象:由于电磁力作用下,使得坩埚中心部分的钢液上升,中心部分钢液上升必然引起边缘部分钢液下落。如此循环促使钢液不停运动起到电磁搅拌作用,有利于金属液的化学成分和温度均匀以及非金属夹杂物、气体上浮。不利方面是引起的“驼峰”现象将炉渣流向坩埚四周,坩埚中心金属液暴露于空气中易吸气和氧化。 (2) electromagnetic stirring phenomenon: due to the effect of electromagnetic force, the steel fluid in the central part of the crucible rises, and the rising of the steel liquid in the center inevitably causes the falling of the steel fluid in the edge part. This cycle promotes the continuous movement of the molten steel, which ACTS as an electromagnetic stirring, which is beneficial to the chemical composition and temperature of the metal liquid, as well as the non-metallic inclusions and gas floats. The disadvantage is that the "hump" phenomenon causes the slag to flow to the crucible, and the metal liquid in the center of the crucible is exposed to air and is easy to inhale and oxidize.   围绕上述情况,根据流体力学理论和金属液、气体、夹杂物的密度关系,确立了熔炼过程中气体、夹杂物分布与处于的方位。 Based on the above situation, the distribution and orientation of gas and inclusions in the smelting process are established according to the relation between the fluid mechanics theory and the density of metal liquid, gas and inclusions.
