no. 1 approach

[0050] This embodiment provides a wire rod for deep drawing, especially a wire rod for drawing 5000MPa class diamond wire. Of course, it can be understood that the wire rod can be used to draw a 5000MPa diamond wire busbar, but it is not limited thereto, for example, it can also be used to draw other steel wire products according to the actual production needs of the enterprise.

[0051] The chemical composition of the wire rod includes: C: 1.01-1.10%, Si: 0.15-0.40%, Mn: 0.30-0.60%, Cr: 0.01-0.40%, and B: 0.0005-0.0020% and V : 0.01~0.09% any one or both of the two; the rest is Fe and unavoidable impurities, of which impurities include Al≤0.003%, Ti≤0.0008%, S≤0.005%, P≤0.008%, O≤ 0.0010% and N≤0.0020%.

[0052] The core idea of ​​the design of the chemical composition of the wire rod in the present invention is to increase the content of pearlite strengthening elements, especially the content of C element, while ensuring controllable structure and avoiding the formation of ...

no. 2 approach

[0107] This embodiment also provides a wire rod for deep drawing, especially a wire rod for drawing 5000MPa grade diamond wire, and a production method of the wire rod. The difference between this embodiment and the foregoing first embodiment lies only in the steel ingot remelting process in the production method, and other technologies are the same as the foregoing first embodiment. In the following, only the differences between this embodiment and the aforementioned first embodiment will be introduced, and the rest of the same parts will not be repeated.

[0108] In this embodiment, the process (2) steel ingot remelting process of the production method is specifically as follows.

[0109] In the steel ingot remelting process, the steel ingot is processed by vacuum self-consumption remelting, and the remelting speed is 3.0-3.5kg / min to obtain a remelted ingot. The chemical composition of the remelted ingot is C, Si, Mn, Cr, And either or both of B and V, the rest are Fe and ...

no. 3 approach

[0115] This embodiment also provides a wire rod for deep drawing, especially a wire rod for drawing 5000MPa grade diamond wire, and a production method of the wire rod. The difference between this embodiment and the foregoing first embodiment lies only in the steel ingot remelting process in the production method, and other technologies are the same as the foregoing first embodiment. In the following, only the differences between this embodiment and the aforementioned first embodiment will be introduced, and the rest of the same parts will not be repeated.

[0116] In this embodiment, the process (2) steel ingot remelting process of the production method is specifically as follows.

[0117] In the steel ingot remelting process, the steel ingot obtained in the vacuum smelting process is firstly subjected to electroslag remelting treatment under a protective atmosphere; The melting speed is 3.0-3.5kg / min, and the remelted ingot is obtained. The chemical composition of the remel...

Abstract

The invention discloses a wire rod for a 5000MPa-grade diamond wire and a production method thereof. The wire rod comprises the following chemical components: 1.01%-1.1% of carbon, 0.15%-0.4% of silicon, 0.3%-0.6% of manganese, 0.01%-0.4% of chromium, 0.0005%-0.002% of boron and / or 0.01%-0.09% of vanadium, and the balance iron and impurities including less than or equal to 0.003% of aluminum, less than or equal to 0.0008% of titanium, less than or equal to 0.005% of sulfur and less than or equal to 0.008% of phosphorus. The production method comprises the steps of vacuum melting, remelting, coping after cogging / forging, high-speed wire rolling and cooling, wherein the casting temperature ranges from 1580 DEG C to 1620 DEG C, and the casting speed ranges from 300 kg / min to 400 kg / min. The center carbon segregation of the wire rod is larger than or equal to 1.00 and smaller than or equal to 1.03, the wire rod can be used for preparing 5000 MPa-grade steel wires of 40-46 microns, and the technical blank of wire rods for ultrahigh-strength diamond wire buses at home and abroad is filled.

Description

technical field [0001] The invention belongs to the technical field of material preparation, and relates to a production method of a 5000MPa diamond wire wire rod and a wire rod prepared by the production method. Background technique [0002] Cutting wire, also known as cutting wire, cutting steel wire, and cutting wire, is a special wire used for cutting, and it is also a special steel wire with a diameter of less than 0.20mm and a galvanized copper surface. It is widely used as a consumable material In the field of energy, aviation, equipment and public facilities. Diamond wire, as a high-carbon cutting steel wire embedded with fine diamond particles on the surface, is mainly used for cutting and forming materials such as solar silicon wafers, quartz materials, monocrystalline silicon, polycrystalline silicon, and diamonds. [0003] In order to reduce the loss of the material to be cut, such as silicon material, during the cutting process, the diamond wire is developing i...
