The invention relates to the field of gas atomization powder preparation, and provides novel metal powder preparation equipment and a method. The problems that in the actual metal powder production process, the defects of low yield, large energy consumption and the like still exist all the time, and consequently the price of powder materials is high are considered. The metal powder preparation method provided by the invention mainly considers that two streams of molten steel jet flow collide with each other at a certain speed to form a leaf-shaped liquid film structure, and the structure is subjected to instability breakage to form the metal powder finally. The equipment mainly is mainly composed pressurized smelting crucibles, flow guide pipes, heating coils, blocking sleeves, blocking plates and an atomization furnace body. By means of the equipment and method provided by the invention, the preparation yield of the metal powder can be effectively increased, and energy consumption isreduced.
Description
technical field [0001] The invention relates to the field of metal powder preparation, in particular to a novel and efficient metal powder preparation equipment and a metal powder preparation method using the equipment. Background technique [0002] With the development of metal additive manufacturing technology, powder steel and injection molding, the demand for high-quality metal powder is increasing. The current metal powder preparation methods mainly include gas atomization method, plasma rotating electrode method and plasma atomization process, etc., but these powder making methods generally have the disadvantages of low output, high cost and high energy consumption, which leads to the loss of powder materials. The price has been high, and the annual output is limited by the preparation method. Contents of the invention [0003] The purpose of the present invention is to provide a novel and efficient equipment for preparing metal powder and a method for preparing met...
