Problems solved by technology

However, due to the limitation of the formation ability of iron-based amorphous alloys, extremely high cooling rates are required during the preparation process.
The currently widely used copper mold casting method can only prepare some sensor cores with relatively simple shapes, which urgently requires us to prepare iron-based amorphous alloy sensor cores with the shape shown in Figure 1.

Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings.

[0031] A kind of laser melting three-dimensional molding method of the present invention makes iron-based amorphous sensor probe, comprises the following steps:

[0032] Step 1, preparation of alloy ingot: the chemical formula of iron-based amorphous alloy is Fe 36 co 36 Si 4 B 20 Nb 4 , converted from atomic percentage to mass percentage; use high-purity raw materials Fe, Co, Si, B, Nb, weigh each raw material according to the composition of the iron-based amorphous alloy, and then put each raw material into a high-temperature furnace prepared in advance , in the presence of protective gas, the alloy is repeatedly smelted at high temperature to prepare a master alloy ingot; wherein, the protective gas includes one or a mixture of argon, nitrogen, etc.; the purity of the protective gas requires a volume percentage greater than 98% ;

[0033] Step 2, using gas ato...

Abstract

The invention discloses a method for manufacturing an iron-based amorphous sensor probe by laser melting stereoforming, which comprises the following steps: firstly preparing an alloy ingot, and making the master alloy ingot into an amorphous powder by gas atomization technology; using CAD software, according to the sensor The probe draws the corresponding stereogram to obtain the CAD model; turns on the metal 3D printer; hangs the amorphous powder as a consumable in the material rod; levels the platform of the metal 3D printer; uses slicing software to slice and generate executable files; The printer starts to print; after the printing is completed, the model is shoveled down with a shovel to obtain the iron-based amorphous sensor probe. The present invention will undoubtedly play a great role in promoting the enrichment of the theory of mine support magnetic monitoring and early warning, improving the production safety of the coal mine industry, and promoting the application of iron-based amorphous alloy materials, and has great theoretical value and potential economic benefits.

Description

technical field [0001] The invention relates to a method for stereoforming an iron-based amorphous sensor probe by laser melting. Background technique [0002] Mine pressure accident is one of the three major disasters in coal mine production, which not only causes huge economic losses, but also seriously threatens the life safety of underground workers. At present, the number of coal mine accidents and the death toll caused by them remain high. According to analysis, the vast majority of mine fatal accidents are caused by the failure of mine pressure support or failure to timely and accurately warn. With the advancement of support technology, supports and hydraulic props made of ferromagnetic materials such as steel are more and more widely used in mine support, and it is particularly important to monitor their stress and working status in real time and non-destructively. Timely and accurate understanding of the local stress change law of mine support equipment before the...
