description The invention relates to a method for sintering a tungsten alloy material by using a high flow rate of gas, which is mainly suitable for a sintering process of realizing mass production of tungsten alloy blanks through an indirect heating sintering method. The process provided by the invention is characterized by introducing a high flow rate of gas during sintering, so that mass sintering of tungsten alloy blanks is realized in deed; the batch of a single furnace is up to 300kg or above; the sintered tungsten alloy blanks are high in density, uniform and consistent in structure and property, low in sintering cost and high in subsequent calendering yield; and the production cost is greatly lowered, and the production efficiency is increased.
