Bimetal metallurgical bonding composite seamless pipe billet production device

The invention belongs to the technical field of composite pipe production equipment, and particularly relates to a bimetal metallurgical bonding composite seamless pipe billet production device. The bimetal metallurgical bonding composite seamless pipe billet production device comprises a rotating device, a preheating lifting table and an electric slag furnace lifting table. Outer-layer hollow materials are heated through the preheating lifting table, the preheating lifting table comprises a preheating device and a lifting device, the preheating device is arranged on the lifting device, and the preheating device can be driven by the lifting device to move in the longitudinal direction. The outer-layer hollow materials are driven by the rotating device to rotate, and the rotating device islocated below the preheating device. Core bar materials are driven by the electric slag furnace lifting table to move to stretch into the outer-layer hollow materials, the electric slag furnace lifting table comprises a lifti
