Embodiment Construction

[0011] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0012] The strip spraying device of the present invention is mainly used for producing nanocrystalline strips.

[0013] figure 1 It is a schematic structural view of the strip spraying device of the present invention, as shown in the figure, the device includes a crucible 11, a cladding 12, a cover 13, a heating silicon carbon rod 14, a water cooling device 15, a temperature sensor 21, and a float rod 22 , Air intake pipe 23, air outlet pipe 24, funnel 31, stopper rod 32, nozzle 33.

[0014] The crucible 11 is used to accommodate molten steel. The bottom of the crucible has a plug hole 16. The plug hole 16 adopts a separate structure. When the thickness of the bottom of the crucible 11 is limited, the effective length of the plug hole 16 is guaranteed. The plug hole 16 is easy The worn part is easier to replace with ...

Abstract

The invention relates to a strip spraying and manufacturing device. The device comprises a crucible, a cladding shell, a cladding cover, a heating globar, a water cooling device, a temperature sensor, a floater rod, an air intake pipe, an air exhaust pipe, a funnel, a stopper rod, a nozzle and the like. When molten steel in the crucible reaches a set liquid level value, pressure of a sealed space formed by the cladding shell and the cladding cover reaches the set pressure value and the temperature of the molten steel in the crucible reaches the set temperature value, the stopper rod is controlled. The molten steel in the crucible flows out sequentially through the stopper hole and the nozzle. High-density nanocrystalline strips are produced with the strip spraying and manufacturing device with low cost, the technology stability is good and the nanocrystalline strips can be manufactured in a sprayed mode at a low temperature.

Description

technical field [0001] The invention relates to a strip spraying device, in particular to a pressure spraying device for nanocrystalline strips. Background technique [0002] The traditional process of preparing nanocrystalline ribbons is as follows: melting through a medium-frequency induction furnace, pouring into a tundish, bottom injection into a belt spraying bag, and spraying molten steel from a nozzle onto a high-speed rotating crystallizer, and instantly solidifying to a thickness of 25 - 30 μm thin ribbon. [0003] In order to stably produce ultra-thin nanocrystalline ribbons with higher density and high saturation magnetic induction, it is necessary to use special pressure spraying equipment, and the special pressure spraying equipment is expensive to make tapes, and the preparation technology requirements are also high. Contents of the invention [0004] The purpose of the present invention is to provide a ribbon spraying device for the defects of the prior art...
