Epc was rarely used in bottom ladle casting. In the case, the casting system was tilted with the mold, which was in accordance with the inner gate entry principle of "oblique entry of circular parts and bobbin castings" under the guidance of "three field theory" of EPC. The runner bending can effectively buffer the inertia impact of metal liquid, which provides a favorable condition for the use of bottom leakage ladle. The inner gate cut in with the inclination of the mold can reduce the impact of molten steel on the mold wall, with reasonable flow field and less heat loss. When the liquid steel level and the nozzle are parallel, the inclined cut can make the molten steel rotate in the shape of the wall under the action of inertia force to balance the heat of the molten steel at the top, which is more conducive to improving the feeding effect of each riser.
