The invention discloses a copper melting vertical furnace. The copper melting vertical furnace comprises a furnace body shell, an anti-collision section and a pre-heating section, wherein the anti-collision section is fixed on the furnace body shell; and the edge length of the edge, located in a vertical plane and close to a sealing brick of the anti-collision section, of the pre-heating section is 300mm to 800mm. Visibly, according to the copper melting vertical furnace provided by the invention, the edge length of the edge, located in the vertical plane and close to the sealing brick of the anti-collision section, of the pre-heating section is much longer than the edge length of the edge located in the vertical plane of an arc-shaped brick in the prior art, so that a transverse pointing joint (namely a pointing joint between the upper and lower adjacent sealing bricks) in the inner wall of a sealing brick building structure is greatly reduced. The transverse pointing joint is a place where loosening and displacement, crushing or falling are generated most easily due to collision of an anti-collision steel plate. Therefore, compared with the prior art, the copper melting vertical furnace provided by the invention can effectively avoid economic loss caused by the fact that the sealing bricks are loosened and crushed or fall onto the bottom of the furnace; and the service life of the vertical furnace can be prolonged, the working efficiency of the vertical furnace is improved and the production cost is reduced.
