Electromagnetic heating furnace

An electromagnetic heating furnace relates to heating furnaces and can solve the problem that an existing electric heating furnace is large in heat energy loss and low in heat efficiency. A stainless steel inner container, a connecting tube and a circulating pump are arranged in an outer shell of the electromagnetic heating furnace, an insulating layer is respectively fixed on the upper surface of the stainless steel inner container, a part of the inner lateral wall of the outer shell between the upper surface of the stainless steel inner container and the inner surface of the lower bottom plate of the outer shell and the inner surface of the lower bottom plate of the outer shell. Two ends of the connecting tube are communicated with an inner cavity of the stainless steel inner container, electromagnetic coils are wound on the outer lateral wall of the connecting tube, and the connecting tube is communicated with a water inlet tube. A water inlet of the circulating pump is communicated with the inner cavity o
