Background
A by-product generated in blast furnace ironmaking is processed and mainly used for manufacturing building materials. In the production process of the blast furnace, after various raw materials and fuels entering the furnace are smelted, besides molten iron and a byproduct blast furnace gas, gangue in iron ore and ash in the fuel are fused with a flux to form liquid slag, the liquid slag is generally at 1450-1550 ℃, and the liquid slag is discharged from a slag hole and an iron hole at regular time. The slag discharged from the slag hole is generally called as "upper slag", the slag discharged from the iron hole together with the molten iron is called as "lower slag", a small amount of molten iron is often mixed in the lower slag, the chemical composition of the blast furnace slag depends on the raw material composition, the metallurgical grade, the operation method and the furnace conditions in the smelting process, CaO, MgO, SiO2 and Al2O3 in the blast furnace slag are main compositions, account for more than 95% of the total amount, besides, the slag also contains a part of elements such as sulfur, titanium, iron, potassium, sodium and the like, and when separating the slag, a certain amount of molten iron is still adhered on the slag, if the slag is directly discarded, the slag causes great waste, the materials can be recycled, and the gasification slag also causes environmental pollution if the gasification slag is directly discarded, and the gasification slag contains a large amount of carbon, the gasification slag needs to be filtered before the decarburization reaction, but most of the stirrers on the ceramic filter are lack of a cleaning device, therefore, slag is accumulated at the bottom of the slurry tank for a long time, so that the stirrer cannot normally operate, the service life of machinery is shortened, and when gasification slag is poured, the slag is adhered to the inner wall of the inlet, so that the inlet is easily blocked.
