Problems solved by technology

The existing spray belt pressure generally adopts two methods of controlling the liquid steel height or gas pressurization. The defect of the former is that the molten steel is solidified at the end of the operation, which may block the nozzle and cause waste; the defect of the latter is that it cannot be operated continuously and affects work efficiency.

Embodiment Construction

[0016] The present invention will be further described by embodiment now in conjunction with accompanying drawing.

[0017] The strip spraying device of the present invention is as shown in the figure, the crucible 1 upper connection port as spraying device is connected with a draft tube 2 whose lower end extends to the bottom of the crucible 1, and the crucible 1 passes through the gas delivery pipe from its upper connection port 7 and the regulating valve 3 arranged on the gas delivery pipe 7 are connected to the inert gas storage tank 4, and the nozzle 5 is connected to the lower connection port of the crucible 1;

[0018] The preparation method of the strip of the present invention is to input the pressure gas into the sprayer while inputting the molten steel into the sprayer, and adjust the input spraying method manually or automatically according to the change of the molten steel level in the sprayer. The pressure of the gas of the injector is used to maintain the stabil...

Abstract

The invention discloses an amorphous and nano-crystalline alloy strip with a simple structure, uniformity in spouted zone and capability of continuous work as well as a simple and easily-implemented device and a method for the amorphous and nano-crystalline alloy strip. The device comprises a crucible, a spray nozzle, a diversion pipe and an inertia gas conveying pipe, wherein the crucible and the spray nozzle are mutually connected; the diversion pipe and the inertia gas conveying pipe are respectively connected onto the crucible; and the gas conveying pipe is connected with an adjusting valve. According to the method, the liquid level of the spray nozzle and the gas pressure are respectively controlled so as to control the stability of the pressure of the spouted zone.

Description

technical field [0001] The invention relates to the preparation of amorphous soft magnetic alloy strips, and more specifically relates to a preparation device and method for amorphous nanocrystalline alloy strips. current technology [0002] Amorphous alloy strips are sprayed by rapid condensation at nearly one million degrees per second. The production of high-performance strips requires a certain pressure on the molten steel. The existing spray belt pressure is generally controlled by liquid steel height or gas pressurization. The defect of the former is that the molten steel is solidified at the end of the operation, which may block the nozzle and cause waste; the defect of the latter is that it cannot be operated continuously and affects work efficiency. Contents of the invention [0003] The object of the present invention is to provide a device and method for producing amorphous and nanocrystalline alloy strips in order to solve the problems in the above-mentioned pr...
