流动粒子炉(又称流化床或沸腾层炉)是二十世纪五十年代才发展起来的一种新型的热处理设备。它的加热介质既不是气体,也不是液体(盐浴或金属溶液),而是固体颗粒和气体的混合物,它应用流态化新技术,将零件置于沸腾的带电粒子中均匀加热,据国内外资料介绍,具有用电省、升温快、工件不脱碳、不腐蚀、表面光洁、 Mobile particle furnace (also known as fluidized bed or boiling furnace) was developed in the 1950s, a new type of heat treatment equipment. It’s heating medium is neither a gas nor a liquid (salt bath or metal solution), but a mixture of solid particles and gas, which uses fluidized new technology, the parts are placed in boiling charged particles uniformly heated, according to the domestic Introduction of foreign materials, with electricity provinces, fast warming, the workpiece is not decarbonization, corrosion, smooth surface,
