Problems solved by technology

At the same time, the heating time for heat treatment and crystallization in large furnaces is long, generally 5 to 6 hours. Therefore, in order to prevent the oxidation of amorphous products, the heating furnace must pass protective gas or vacuumize. Therefore, the current heat treatment and crystallization energy consumption is large, and the main product performance poor consistency

Embodiment 1

[0030] Example 1: Heat treatment of an annular amorphous material with an inner diameter of 9 mm and an outer diameter of 15 mm and a height of 10 mm

[0031] Such as figure 1As shown, the size of the small furnace 2 is: 8cm high, 20cm long, and 20cm wide; the inner diameter is 9mm, the outer diameter is 15mm, and the ring-shaped amorphous material with a height of 10mm is placed on the loading platform 15 and arranged in rows, and the main power supply is connected. , each device is waiting for work, the set crystallization temperature is 610°C, if the set temperature is inconsistent with the actual temperature, then the temperature controller 7 sends a signal to notify the controller 9, requesting the power supply 11 to provide 1KG power to the heating element 3 in the furnace, Such as resistance wire, controller 9 then informs power supply 11 to output 220 volts and 5 amps of power to heat heating element 3 in the furnace. After about 10 minutes, the temperature in the furn...

Embodiment 2

[0032] Embodiment 2: heat treatment 8mm wide amorphous strip

[0033] Such as figure 2 As shown, the size of the small furnace 2 is: 4mm high, 20mm long, and 3mm wide. The amorphous tape reel will be wound on the driven roller 5 or the amorphous tape will be wound on the driven roller 5, and the amorphous tape will be wound. Pass between the heating bodies in the furnace in the small furnace 2, wind on the tape reel and install on the driving roller 14 or directly roll on the driving roller 14, turn on the main power supply, each device enters the working state, and the temperature control The instrument 7 sets the crystallization temperature to be 610°C. At this time, the temperature sensor 6 in the furnace, such as a thermocouple, measures the temperature in the furnace as room temperature, and the set temperature is different from the temperature in the furnace. The temperature controller 7 sends a signal to the controller 9, requiring Provide 600W power heating element 3...

Abstract

The invention discloses a device for conducting heat treatment on a non-crystalline material through a small furnace hearth method. The device comprises a small furnace hearth (2), an in-furnace temperature sensor (6), a temperature controller (7), a controller (9), a power supply (11), an in-furnace heating body (3), a non-crystalline detector (17), a metal reflecting screen (4) and connecting wires; for a band-shaped non-crystalline material, the device further comprises a driven roller (5) which is arranged at an inlet of the small furnace hearth (2) and used for storing the non-crystalline material to be subjected to heat treatment and a driving roller (14) which is arranged at an outlet and used for storing the non-crystalline material obtained after heat treatment, and the driving roller (14) rotates over control of the controller (9) to drive the non-crystalline material to move in the small furnace hearth (2); for a blocky non-crystalline material, the device further comprises an object carrying platform (15), a pusher (16) and a collector (10), and the pusher (16) pushes the non-crystalline material placed on the object carrying platform (15) to enter the small furnace hearth (2) over control of the controller (9). According to the device and method, the uniformity of the properties of products obtained after crystallization treatment can be significantly improved, and energy sources can be obviously saved.

Description

technical field [0001] The invention relates to an amorphous material crystallization heat treatment device and method, in particular to a furnace method crystallization heat treatment device and method for amorphous material. Background technique [0002] As we all know, the performance of amorphous materials is closely related to the crystallization heat treatment temperature. Currently, the heat treatment and crystallization of amorphous materials are heated in a large furnace. Generally, the diameter of the furnace is about 60 cm, and the height of the furnace is about 50 cm. In a large furnace, the temperature difference between the furnace center and the furnace periphery is large, and there is a large temperature difference between the upper part of the furnace and the bottom of the furnace. Since there is a large temperature difference in different positions during crystallization, the performance of the product cannot be completely consistent. If the performance of ...
