Abstract：Based on the production of SS400 steel by continuous casting slab in a certain factory, the typical steel leakage phenomenon was analyzed through chemical composition analysis, continuous casting parameters analysis, the FDA curve analysis, steel image analysis and the real reason for the leakage of steel was found. It was mainly caused by the leakage of steel slag, and effective measures were taken to prevent similar production accidents in the future. Measures included: to ensure the overheat temperature of the molten steel in the tundish between 15 to 35℃ in the steelmaking section; in accordance with the relevant provisions of 0.1 m/min every time when reduce speed to ensure the smooth production and improve the continuous casting machine operation efficiency.
