Problems solved by technology

[0006] For this reason, the present invention aims to solve the problem that the heating device and method in the prior art cannot keep the temperature of the nozzle relatively constant, causing the nozzle to be blocked by precipitates during the cooling process, and provides a nozzle heating device for the preparation of amorphous strips. The system and method realize scanning and uniform heating of the nozzle during use, which can prevent the temperature of the nozzle surface from decreasing, prevent the inclusions from being precipitated in the nozzle slit and cause the nozzle to be blocked, and realize the complete automatic control of the nozzle temperature through closed-loop control

Embodiment 1

[0045] The nozzle heating device for the preparation of amorphous strip according to the present invention, such as figure 1 As shown, the flame heating device 7 is included. In this embodiment, on the actual equipment, the nozzle 4 is installed under the nozzle package 3, and the flame heating device 7 is arranged on one side of the nozzle 4, which can be around the nozzle 4. On any side, and the flame heating device 7 can be set horizontally with the nozzle 4, or at a certain angle, depending on the needs of the industry. In this embodiment, the flame heating device 7 is provided with one, horizontal It is arranged on one side of the nozzle 4, so that the flame 5 can be sprayed on the side wall of the nozzle 4, and the nozzle 4 is heated, so that the temperature of the nozzle 4 will not decrease with the rotation of the cooling roller 1, and the nozzle 4 is prevented from falling with the rotation of the cooling roller 1. When the cooling roll 1 is rotated and the temperatur...

Embodiment 2

[0053] On the basis of the nozzle heating device described in Embodiment 1, two flame heating devices 7 are arranged on opposite sides of the nozzle respectively, and the flame heating device 7 is a flame spray gun in this embodiment, Such as Figure 4 As shown, the flame spray gun is provided with at least one gun head 6, and when the nozzle width is 142mm, the gun head 6 is provided with 6-8 in the present embodiment, and the position of the gun head 6 is usually far from the flame There is a certain distance on the edge of the spray gun, and at the same time, there is a distance of at least 20mm between each of the gun heads 6. In order to ensure that the flame 5 ejected by the flame spray gun during the left and right translation process can always cover the entire length range of the nozzle 4, And excluding the influence of edge effects, the width of the flame spray gun is at least twice the length of the nozzle 4 . The shape of the gun head 6 is flat and long in this em...

Embodiment 3

[0057] A temperature control system using the nozzle heating device described in the above embodiments, such as figure 2 As shown, it includes a temperature measuring device 11, a control unit 10 and the nozzle heating device. The temperature measuring device 11 is preferably an infrared thermometer, and the infrared thermometer can be used to realize remote non-contact temperature measurement. In the prior art, the problem of using the thermistor to measure at a high temperature position is high consumption and equipment loss is fast, and the infrared thermometer is a relatively advanced temperature remote measurement technology at present, and its measurement is accurate and fast, and can quickly and accurately reflect The change of temperature, described infrared thermometer is arranged on the side of nozzle 4, and its position is with the distance of the farthest accurate measurement nozzle 4 temperature, is horizontally arranged on nozzle 4 side in the present embodiment,...

Abstract

Disclosed are a nozzle heating device and a temperature control system and method for manufacturing of amorphous strips. The temperature control system comprises a fire heating device, a control unit and a temperature measuring device. The fire heating device is arranged on one side of a nozzle, fire of the same is jet to the side wall of the nozzle, the nozzle is heated, the control unit receives a detecting signal for the temperature measuring device, processes the detecting signal to obtain a control command, and controls the fire intensity of the fire heating device, and by heating the nozzle, precipitates can be prevented from blocking the nozzle, oxidation of the nozzle and a melting puddle can also be reduced, quality of the produced amorphous strips can be improved. Besides, the temperature control system can keep the temperature of the nozzle within a reasonable range, and cracking and damage due to overhigh temperature or too large temperature difference are avoided.

Description

technical field [0001] The invention relates to a manufacturing technology of an amorphous strip, in particular to a nozzle heating system and method for preparing an amorphous strip. Background technique [0002] After the metal is melted, the internal atoms are in an active state. When the metal starts to cool, the atoms will gradually arrange in an orderly manner according to a certain crystal state law as the temperature drops, forming a crystal. If the cooling process is fast, the atoms are solidified before rearrangement, thus producing an amorphous alloy. Compared with the crystalline alloy, the amorphous alloy has different physical properties, chemical properties and mechanical properties. There have been significant changes; taking the iron-based amorphous alloy as an example, it has the characteristics of high saturation magnetic induction and low loss. Due to such characteristics, amorphous alloy materials are used in electronics, aviation, aerospace, machinery, ...
