The invention relates to the technical field of metallurgy, in particular to microwave metallurgy equipment and a using method thereof. The microwave metallurgy equipment specifically comprises a furnace body and a furnace chamber inside the furnace body, a supporting mechanism is arranged below the furnace body, a supporting base, an object containing table and a sealing structure are arranged atthe bottom of the furnace body, and the object containing table is embedded into the bottom of the furnace body; a lifting mechanism and a rotating device are arranged below the supporting base, a travelling device and a rail are arranged below the lifting mechanism, and a modularized high-temperature-resistant thermal insulation material fills the portion between the furnace body and the furnacechamber inside the furnace body; and a smoke flue is arranged on the side wall of the furnace body, a microwave emission end is arranged at the top of the furnace body, a hollow cavity is formed between the microwave emission end and the furnace chamber, the hollow cavity is formed by laying a wave-transmitting and non-wave-absorbing thermal insulation isolation plates in a surrounding mode, anda cooling hole and a cooling fan are arranged on the two sides of the hollow cavity correspondingly. According to the microwave metallurgy equipment, the problems that the furnace body is complex andtime-consuming to construct, sealing of the furnace bottom is difficult, and heating of materials is not uniform are solved, and the situation that the high-temperature electric arc is generated during microwave guiding by a waveguide pipe at the microwave emission end is avoided.
