Abstract

The invention discloses an additive manufacturing smelting furnace. The additive manufacturing smelting furnace specifically comprises a smelting furnace and a smelting gas injection head; the smelting furnace is provided with a smelting furnace body and a top smelting furnace body pipe, a top exhaust head is arranged at the top of the smelting furnace, and a flue gas treatment device is arranged in the top exhaust head; the smelting gas injection head is provided with a gas injection head body and a gas return pipe arranged above the smelting gas injection head, and the upper end and the lower end of the gas return pipe communicate with the top smelting furnace body pipe. The invention relates to the technical field of additive manufacturing. According to the additive manufacturing smelting furnace, the problems that much flue gas is generated during smelting, and part of particle powder is wasted due to direct emission are solved, stirring and mixing of internal smelted materials are improved, the smelting efficiency of the internal materials is improved, the internal pressure is increased, smelting of the internal materials can be accelerated, and the internal materials are prevented from adhering to the inner wall of the smelting furnace during smelting.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing, in particular to an additive manufacturing melting furnace. Background technique [0002] Additive manufacturing, commonly known as 3D printing, is a combination of computer-aided design, material processing and forming technology, based on digital model files, through software and numerical control system, special metal materials, non-metal materials and medical biological materials, according to extrusion, Sintering, melting, light curing, spraying, etc. are accumulated layer by layer to create a manufacturing technology for physical objects. In additive manufacturing, a melting furnace is usually required to melt metal raw materials to provide printing materials for additive manufacturing. Traditional smelting furnaces have fuel heating and electric heating. For fuel-heating smelting furnaces, since more smoke is generated during smelting, direct discharge will cause a part of ...
