Rapid evaluation method for molten steel inclusions in CSP production

The invention discloses a rapid evaluation method for molten steel inclusions in CSP production, and the method comprises the following steps that the first content of Si element in molten steel after converter steelmaking is measured, and the first content is taken as a basic value for evaluation; the second content of the Si element and the first variable quantity of the Si element after converter tapping are measured, whether the first variable quantity is larger than a first limiting threshold value or not is judged, and if so, the slag amount during converter tapping is too large, and a tapping hole is replaced; the third content and the second variable quantity of the Si element after refining treatment are measured, whether the second variable quantity is larger than a second limiting threshold value or not is judged, and if so, the metallurgical auxiliary material has problems; and the fourth content of the Si element after tundish continuous casting and the third variable quantity of the Si element a
