High-temperature-resistant copper rod suitable for non-ferrous metal rolled product

The utility model provides a high-temperature-resistant copper rod suitable for a non-ferrous metal rolled product, belongs to the technical field of copper rods, and aims to solve the problems that the conventional copper rod often works in a high-temperature environment during use, and the use of the conventional copper rod is influenced due to deformation caused by thermal expansion after long-time use. Comprising a high-temperature copper rod layer, a first heat-insulating ceramic layer, a second heat-insulating ceramic layer, a supporting iron rod and a plugging block, the first heat insulation ceramic layer is fixedly connected to the inner wall of the high-temperature copper rod layer; the second heat insulation ceramic layer is fixedly connected to the interior of the first heat insulation ceramic layer, and a gap is formed between the second heat insulation ceramic layer and the first heat insulation ceramic layer; the supporting iron rod is fixedly connected to the inner wall of the second heat insu
