Non-vacuum gas atomization continuous powder making equipment and powder making method

Abstract

The invention relates to non-vacuum gas atomization continuous powder making equipment and a powder making method, and the non-vacuum gas atomization continuous powder making equipment comprises a smelting furnace which is used for smelting raw materials into molten steel; the tundish bottom pouring furnace is used for receiving molten steel and preserving heat and comprises a bottom pouring furnace body, a cover body and a plug rod. The atomizing tower is used for condensing molten steel liquid drops atomized into the atomizing tower into metal powder; a support is arranged on the tundish furnace body rotating moving trolley and used for symmetrically placing tundish bottom pouring furnaces, a material receiving station is arranged at one end of the tundish furnace body rotating moving trolley, and a powder making station is arranged at the other end of the tundish furnace body rotating moving trolley. According to the non-vacuum gas atomization continuous powder making equipment, smelting is carried out under the non-vacuum condition, casting powder can be added on the molten steel surface, molten steel oxidation is prevented, meanwhile, the risk that slag on the liquid surface flows into the leakage ladle is avoided, long-time continuous powder making can be achieved, the product performance is better, and energy is saved.

Description

technical field [0001] The invention belongs to the technical field of metal powder making, and in particular relates to non-vacuum air atomization continuous powder making equipment and a powder making method. Background technique [0002] Gas atomization pulverization refers to the use of high-speed airflow to crush the liquid metal flow to form small droplets, followed by rapid condensation to obtain shaped powder. Gas atomization technology has become the most important method for preparing fine spherical metal and alloy powders. [0003] The existing gas atomization production mode layout includes the following types, smelting in the atmosphere, double furnace opposite pouring method, melting under vacuum or protective atmosphere, double furnace or multiple furnace pouring method.
