How to reduce inclusions in X70 Pipeline

The way to control non-metallic inclusions in X70 pipeline steel is to reduce the generation of inclusions during the smelting and pouring process and the pollution of X70 pipeline molten steel by foreign inclusions; the second is to try to eliminate the existing inclusions in X70 pipeline steel, in the refining process, there are mainly the following ways to remove X70 pipeline steel inclusions:

(1) Non-metallic inclusions float up in the ladle due to buoyancy, and after reaching the liquid steel surface of the X70 pipeline, enter the slag to be removed. Generally, non-metallic inclusions with large particles are easier to float and separate.

(2) By blowing gas from the bottom, the non-metallic inclusions in the X70 pipeline steel float up and separate with the air bubbles.

(3) Some non-metallic inclusions with small particles collide with each other in the highly turbulent (stirring of gas, etc.) ladle furnace refining process to generate non-metallic inclusions with larger particles, which are removed by floating.
