The invention relates to the field of heating furnaces, and discloses a fuel gas type sintering furnace. The fuel gas type sintering furnace comprises a furnace body, a sintering crucible, a first thermocouple and a second thermocouple, the furnace body is provided with a fuel gas connector and an exhaust connector, the fuel gas connector is connected with a fan connector, an electronic igniter is arranged in the fuel gas connector, the sintering crucible comprises a crucible body and a crucible cover, the crucible body is detachably arranged in a hearth, a gas channel is arranged between the crucible body and the inner wall of the furnace body, the crucible cover covers the crucible body, and the crucible cover is provided with a gas inlet and a gas outlet which are connected with a nitrogen pipeline. According to the fuel gas type sintering furnace, the crucible body is placed in the hearth of the furnace body, fuel gas enters the fuel gas connector of the furnace body and is ignited through the electronic igniter, flames (hot gas) of the fuel gas are blown into the gas channel under the action of the high-pressure fan, a workpiece is heated, the heating speed is high, and the heating efficiency is improved; and the workpiece is protected through nitrogen, so that the workpiece cannot be oxidized during heating.
Description
technical field [0001] The embodiment of the present invention relates to the field of heating furnaces, in particular to a gas-fired sintering furnace. Background technique [0002] The sintering furnace refers to the special equipment for obtaining the required physical and mechanical properties and microstructure by heating the powder compact, and it is also used for heat treatment of workpieces such as copper and steel strips. [0003] However, the sintering furnace in the prior art is generally heated by electric heating wires, the heating time is long, the heating efficiency is low, and the workpiece is prone to oxidation during the heating process. Contents of the invention [0004] The object of the present invention is to provide a gas-fired sintering furnace to solve the above-mentioned problems in the background technology. [0005] An embodiment of the present invention provides a gas-fired sintering furnace, including: a furnace body, a sintering crucible, a ...
