Abstract
The invention relates to a device and a method for preparing an amorphous alloy strip by one-ladle rotary constant pressure. A nozzle opening is formed in the connecting position of a steel ladle wall and a steel ladle bottom, and a steel ladle is integrally reclined when in smelting, so that the nozzle opening is upward. When an amorphous alloy in the steel ladle is heated and melted to reach a specific temperature by medium-frequency induction, the nozzle opening rotates around the arc-shaped surface of a cooling copper roller to reach a preset proper position by the aid of a mechanical rotation transmission device, the nozzle opening is transformed from facing upward to facing downward, and then an external gas constant pressure device is automatically started. Under the combined action of molten steel hydraulic pressure, gas pressure and an induction coil, amorphous alloy molten steel in the steel ladle is continuously and stably injected to the surface of the high-speed rotating cooling copper roller by the constant pressure, and the amorphous alloy strip with the thickness of about 15-35 micrometers is formed once. The device is simple, practical, short in technological process, simple and convenient to maintain, convenient to operate, obvious in consumption reduction and high in production efficiency, the thickness of the amorphous alloy strip can be as accurate as + / -0.5 micrometer, the strip is smooth, and yield can reach 93%.
Description
technical field [0001] The invention belongs to the technical field of preparation of amorphous alloys, and in particular relates to a device and method for preparing amorphous alloy strips with a one-pack rotary constant pressure. Background technique [0002] Amorphous alloy melt spraying is one-time molding to prepare metal strips, without the need for repeated rolling and forming of steel ingots by roller presses. It is a breakthrough innovation in metallurgical processing that is green, environmentally friendly, energy-saving and consumption-reducing. The key to the success of spray strip making must be to ensure that the nozzle mouth (nozzle) is clean and complete before spraying and during the spraying process, and that oxidation residues cannot be formed in the mouth due to steel leakage through the nozzle mouth of the ladle or the molten steel is eroded by high-temperature molten steel during the melting process. Nozzle mouth. At the same time, it is necessary to e...
