The size of the iron flow can be seen by yourself. Every year, the main character of "Hot Metal" is the influence of silicon content. The higher the silicon content, the greater the viscosity; The higher the silicon content, the brighter the molten iron, and the white color, giving people the impression that the flow rate is very slow; When the sulfur content is high, the color of molten iron is dark red, and it is easy to hang on the edge of iron ditch when flowing; When the silicon content is high, the spark size is also large, while when the sulfur content is high or the physical heat is low, the spark is small or invisible. The furnace temperature depends on the silicon content, which is a chemical representation. The high silicon content indicates that the furnace temperature is high, and another point is physical heat, which is mainly measured by temperature measuring gun.
Slag alkalinity, slag fluidity is poor, and the color after solidification is white, just like stone, indicating high alkalinity; On the contrary, the fluidity is good, and there are many black or glassy substances after solidification, indicating that the alkalinity is low; Therefore, it is generally necessary to replace glass slag with stone slag as a more suitable slag.
