The present invention pertains to a method for incessantly producing polysilicon ingots, especially fabricated of an equality polycrystalline material. It contains a metallurgical method for continuously producing large amount of polysilicon ingot made by metal silicon, further comprising the steps of aligning empty graphite molds on furnace cars; preheating the molds in the preheating area; pouring the liquidized silicon into the preheated molds; transporting the molds filled with liquidized silicon from the high- temperature area, thence to a medium-temperature area, and then to a low-temperature area for solidifying the liquidized silicon into crystallized silicon; cooling the crystallized silicon until reaching the room temperature by the assistance of a shroud in a rotary conveyer track, thus generating an integral polysilicon ingot. The apparatus comprises a body, a chamber, a track, cars, a front and rear auxiliary cars, a rotary conveyer track, a propulsion apparatus, and an adjusting system.
