Artificial-precious-stone fusing device with heating devices prevented from being eroded

The invention belongs to the field of IPC C04 artificial stone manufacturing, and particularly relates to an artificial-precious-stone fusing device with heating devices prevented from being eroded. The artificial-precious-stone fusing device comprises a fusing pond and the heating devices, and is characterized in that a heat insulation cover is arranged above the fusing pond, upper covering plates extending towards the center of a pond opening are arranged on the two sides of the pond opening of the fusing pond, and heat conducting plates are arranged between the heat insulation cover and the upper covering plates and located at the edges of the upper covering plates; the heating devices are arranged at the portions, on the fusing-pond-exterior-facing sides of the heat conducting plates, of the upper covering plates. By means of the artificial-precious-stone fusing device, artificial-precious-stone raw materials are more evenly fused, the quality of manufactured artificial precious stone is better, the heating devices can be prevented from being eroded, the erosion resistance of the fusing pond can also be improved, the service life of the fusing pond can be prolonged accordingly, and it can also be avoided that structures such as the heating devices are eroded, chips fall into the fusing pond, and the quality of the artificial precious stone is influenced.
