Problems solved by technology

However, the electromagnetic fields formed by the induction coils located on the side wall and bottom of the crucible interfere with each other, resulting in uneven electromagnetic fields inside the crucible body, uneven heating and stirring of the charge, and affecting the uniformity of the alloy.
In addition, when the molten metal flows out from the sprue, the force of the induction coil is lost, and the molte

Abstract

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.

Description

technical field [0001] The invention relates to a cold crucible for induction smelting with full suspension and strong stirring capability, in particular to a cold crucible which uses an electromagnetic field to improve the suspension effect during the suspension smelting process, and belongs to the technical field of smelting. Background technique [0002] Cold crucible vacuum induction smelting (vacuum electromagnetic levitation smelting) is one of the most advanced smelting technologies. It is similar to vacuum intermediate frequency induction smelting. It uses electromagnetic fields to heat metals in a vacuum or inert gas environment to complete the smelting process. It is a non-gas pollution smelting technology. Compared with vacuum intermediate frequency induction melting, cold crucible vacuum induction melting uses electromagnetic levitation force to make the molten metal pool in a suspended state in the crucible, avoiding the pollution of the crucible material to the...
