Why does the medium frequency furnace need to continuously add materials?
The medium frequency furnace needs to continuously add materials during the smelting of phosphorus pig iron. After the medium frequency furnace is sintered, the cross section of the crucible is divided into unsintered layer, semi-sintered layer and sintered layer from the outside to the inside. The thickness of the sintered layer is only 4~6cm.
In the process of adding sharp materials such as returned iron and ferrosilicon, the furnace wall is continuously impacted and stirred by the high-temperature phosphorus pig iron, resulting in dents and thinning of the furnace wall, which in turn affects the life of the furnace. In addition, for high-temperature molten iron, splashing during the feeding process will also pose a serious threat to safe production.
In view of the above reasons, a flow trough tool is used for the subsequent material adding process, which is both safe and prolongs the service life of the furnace lining, effectively solving the above problems.
