Causes of excessive slag in ferrosilicon smelting furnaces
ferrosilicon smelting Sometimes there is a long-term lack of carbon in the furnace, and a large amount of excess silica dissolves to form a sticky slag, which cannot be easily removed.
Smelting ferrosilicon process due to the material surface and other reasons, the electrode into the depth of the charge shallow, low furnace temperature, slag is not easy to exclude, especially the small capacity of the electric furnace is more likely to produce this phenomenon, so that the furnace memory slag too much.
Although the amount of slag is low when smelting ferrosilicon, the slag should be brought outwards as far as possible when discharging the iron in order to make the electrode inserted deeply. If care is not taken to bring slag, over time, this can also result in excessive slag in the furnace.
Poor quality raw materials for ferrosilicon smelting, such as high ash content in the coke or high clay content on the silica surface, can also increase the amount of slag.
These are just a few of the reasons for excessive slag in ferrosilicon smelting furnaces.
