The invention discloses an induction melting cold crucible with full suspension and strong stirring ability. The induction melting cold crucible comprises a crucible body, a main induction coil, a bottom induction coil, a main magnetic field disturbance cylinder and a bottom magnetic field disturbance cylinder, wherein the main induction coil is arranged on the outer side surface of the crucible body, and radial suspension force is applied to a molten pool through the main induction coil, so that the molten pool can be separated from the side surface of the crucible body; the bottom inductioncoil is arranged at the bottom of the crucible; upward suspension force is applied to the bottom of the molten pool through a planar spiral bottom induction coil or a spiral conical induction coil viathe bottom induction coil, so that the bottom of the molten pool is separated from the inner bottom surface of the crucible, full suspension of the molten pool is realized, a smelting temperature isincreased, the uniformity of alloy components is improved, and skull formation is prevented. Besides, a spiral small conical or cylindrical induction coil is arranged at the bottom of the crucible, acting force is applied to cast molten metal, molten metal is located in the middle all the time, and casting is accurate.
