industrial furnace 3d model

Industrial horizontal cylindrical copper retention furnace, transparent technical cutaway diagram. The furnace must have a long horizontal cylindrical body (tube shape), not rectangular, not box-shaped, clearly circular cross-section. Inside the furnace show molten copper bath in orange color occupying the bottom half of the cylinder. The furnace is supported by two lateral refractory supports at both ends. The model should look like a technical schematic, simplified industrial design, similar to a process diagram, with the internal copper visible through transparent walls. On the top center there is a gas burner flame entering the furnace. Style: industrial process diagram, simplified geometry, engineering visualization, clean surfaces, minimal textures. Important: Cylindrical furnace body Horizontal tube shape Circular cross section Not rectangular
