Abstract
The invention discloses a plunger type equal-liquid-level pressure amorphous strip maker. According to the invention, liquid level height is used to generate pressure (0.3-0.4kg/cm<2>) so as to make an amorphous or amorphous nanocrystalline strip (less than 30 mu m), and a movable plunger is used to keep the liquid level height. The plunger type equal-liquid-level pressure amorphous strip maker comprises a non-vacuum induction furnace (71), a pressure sensor (72), a molten steel tank (73), a liquid level height gauge (74), a nozzle bag (75), a heating globar (76), a cooling roller (77), a plunger (78), a plunger lifting rod (79), a magnetic scale (710) and a lifting motor (711). The plunger type equal-liquid-level pressure amorphous strip maker has the characteristics of accurate pressure and convenience in operation, and has the advantages of low cost and high yield as compared with a strip injection machine using gas to apply pressure.
Description
technical field [0001] The invention relates to a tape-making device for manufacturing amorphous alloy or amorphous nano-crystalline soft magnetic alloy, in particular to a plunger type equal liquid level pressure amorphous tape-making machine. Background technique [0002] Since 1960, Professor Guwez in the United States invented the rapid quenching process (cooling speed at 10 6 °C / s) since the preparation of Au-Si series amorphous alloys, due to its microstructure, efficient preparation process, and excellent material properties, it has been paid special attention by material physicists and industry circles. In 1979, Allied-Signal Company of the United States developed the broadband rapid quenching technology of amorphous alloy, which made the large-scale production of amorphous alloy strip possible. In 1989, Allied-Signal Company of the United States had an annual production capacity of 60,000 tons of amorphous strips, of which the representative brand was 2605S-2 and t...
