Abstract: A method of manufacturing V product utilizing fluidization technology and fluidization device comprises: calcining V slag with high Ca in a fluidized furnace, in which the weight ratio of CaO to V2O5 is 0.5-1.4, the average temperature in the fluidized furnace is 850-950?, and the average residence time of the V slag in the furnace is 30-150 minutes; leaching calcined product in sulphuric acid; and producing V product from leach solution. Compared with methods which use rotary kiln or multi-chamber furnace as calcining devices, the method has high production efficiency, low energy consumption and high productivity, and it is easy to realize large-scale manufacture.

Abstract: A firework electrical firing head has a circuit board (7) fixed in a mounting clip (8). There is a firing slot (6) disposed on the front end of the circuit board (7). A resistance wire (5) and leads (9) are welded on the circuit board (7), and the resistance wire (5) is straddled on the firing slot (6). The mounting clip (8) is provided with a firework fuse slot (4). There is a cover (1) provided with a fuse pushing positioning plate (2) and covered on the mounting clip (8). The resistance wire (5) is a resistance wire which has good electrothermal conversion, such as tungsten wire, nickel-chromium alloy wire, constantan wire and so on, and is wound to compact spiral shape.
