The metal lumps or slag lumps embedded under the slab skin are called “cold moles”. The reason is:
(1) During open pouring, the splash of steel flow sticks to the surface of the mold and the cold steel is embedded in the solidified shell;
(2) The liquid level of the crystallizer fluctuates too much, and the insoluble matter in the slag is involved in the solidification shell.
