Abstract：?Low-carbon aluminum killed steel QD08 is mainly used in the manufacture of automobile engine claw， Ds inclusions exceed the standard， seriously affecting its fatigue life. The morphology， size and composition of inclusions were analyzed by Electron microscopy， SEM and EDS. It is suggested that the cleanliness of the molten steel can be improved and the inclusions in the molten steel can be reduced by the continuous casting slag. And by improving the production process， effective control of the large particles in the QD08 Ds kind inclusions， improve Ds inclusions to provide technical guidance for the scene.
