The utility model provides a continuous smelting furnace for producing co-jointed quartz tube and bar which relates to a continuous smelting furnace for producing quartz tube and quartz bar. The utility model is developed mainly for solving the problem that the existing continuous smelting furnace can only produce single quartz tube and bar. The continuous smelting furnace for producing co-jointed quartz tube and bar mainly comprises a furnace body, a heater, heat-insulating materials, a big furnace cover, a small furnace cover, a wolfram copple, a discharge table, core bars, an inlet, etc. The discharge table is provided with two or more discharge holes which are mutually connected. The core bars are respectively and correspondently arranged above each discharge hole. The utility model has the advantage of that the produced quartz tubes and bars are connected in one.
