| description | The present invention relates to a method for predicting surface quality of thin slab hot rolled coil and a method for producing the thin slab hot rolled coil using the same. The method comprises the steps of: calculating Cu equivalent (Cu eq.) of a molten steel; calculating burnt index by applying the calculated Cu equivalent of the molten steel into an equation: 120 (Cu equivalent)-6(Cu equivalent); and predicting surface defect occurrence of the thin slab hot rolled coil by the burnt index. According to the present invention, the method is able to predict burnt defect of the thin slab hot rolled coil by calculating Cu equivalent of the molten steel, and thus improves productivity and product reliability by providing a thin slab which meets the product quality standards demanded by a consumer. |
