ultra-low carbon ferrosilicon
⒌Operating conditions
If the operation is improper, such as uneven mixing, partial addition of materials, and failure to stir the furnace in time. The furnace condition is sticky, the material level is too high or there is a lack of material in the furnace, etc., which will hinder the depth and stability of the electrode insertion into the furnace material.
⒍Iron tapping time
Under normal conditions of the furnace, if the tapping interval is extended or the molten iron is not clean, there will inevitably be more molten iron accumulated in the furnace, the electrode will rise, and the electrode will be inserted shallowly into the charge.

Low titanium (high purity) ferrosilicon
⒎The amount of slag accumulated in the furnace
If the slag discharge is not good, there will be too much slag accumulated in the furnace, the furnace bottom will rise, and the insertion depth of the electrode will become shallow.

high-silicon ferrosilicon
⒏The diameter of the polar center circle between electrodes
For a submerged arc furnace with the same capacity, when the diameter of the pole center circle is larger, the distance between the electrodes is farther, the resistance of the charge increases, and the electrode is inserted deeper into the charge. On the contrary, when the diameter of the pole center circle is smaller, the insertion depth of the electrode becomes shallower.
