| description | The invention belongs to the technical field of composite pipe production processes, and particularly relates to a bi-metal metallurgical bonding composite seamless pipe blank production process. Thebi-metal metallurgical bonding composite seamless pipe blank production process comprises the following steps that S1, raw materials are prepared, specifically, outer-layer hollow materials and inner-layer materials are prepared; S2, preheating is conducted, specifically, the outer-layer hollow materials are preheated; S3, slag is fused, specifically, pre-slag is put into the outer-layer hollow materials and is heated and fused; S4, metallurgical bonding is conducted, specifically, the inner-layer materials extend into the outer-layer hollow materials, and are heated and fused to be combined with the outer-layer materials; and S5, a pipe blank is obtained, specifically, after the inner-layer materials are fused, cooling is conducted and the metallurgical bonding composite metal pipe blankis obtained.
