Various types of dust and sludge are inevitably produced in the main process of metallurgical production. Waste from dry collection is called dust, and from wet collection is called sludge. Due to the shortage of mineral resources and the decline in grades, the output of sintering dust ash, blast furnace iron ash ash, converter and electric furnace steel smelting dust, steel rolling iron dust sludge, copper metallurgical precipitation sludge, etc. in the smelting production process has continued to increase.

What is converter sludge
In the production process of metallurgical enterprises, converter oxygen blowing smelting is a necessary part of the steel making process.
During the converter blowing process, the oxygen injected into the pig iron undergoes an incomplete oxidation reaction with the carbon in the pig iron to form a flue gas containing CO. At the same time, iron and other accompanying metals enter the wet flue gas dedusting system in the form of flue gas as well. The soot carried by the washing sewage is precipitated and exists in the form of water-containing sludge. This is called the converter sludge.
