Copper billet horizontal continuous casting apparatus and process with a vertical shaft furnace for smelting

A copper billet horizontal continuous casting apparatus with a vertical shaft furnace for smelting, comprising:

• the vertical shaft furnace for melting copper;
• a refining furnace for refining liquid copper;
• a mixing furnace connected with the vertical shaft furnace and the refining furnace, for mixing the liquid copper and phosphorous copper, the mixing furnace has a phosphorous copper charging port, a phosphorous copper charger being connected at the phosphorous copper charging port;
• a holding furnace connected with the refining furnace, for continued slag removal;
• and
• a continuous casting furnace connected with the holding furnace, for simultaneously casting multiple strands of billets;
• wherein the refining furnace comprises a furnace body and a gas flushing device disposed beneath the furnace body, a gas flushing brick being disposed at a chamber bottom wall of the furnace body, the gas flushing device blowing an inert gas and/or a reducing gas into the furnace body through the gas flushing brick, a gas inlet device being provided on the vertical shaft furnace for introducing a mixed gas including air and a fuel gas into the vertical shaft furnace, and a detecting device and an adjusting device being further provided on the vertical shaft furnace, the detecting device and the adjusting device being connected with the gas inlet device, wherein the detecting device is configured for detecting a proportion between components in the mixed gas so as to control the adjusting device to adjust the proportion between the components in the mixed gas, thereby maintaining a reducing atmosphere in the vertical shaft furnace.
