Embodiment 1

[0050] A disk element with a diameter of 5.5mm is selected from pure steel with a carbon content between 0.80-0.96%, a silicon content between 0.12-0.40%, and a manganese content between 0.30-0.65%. After heavy drawing, intermediate heat treatment, and intermediate drawing, it is made into intermediate-drawn steel wire with a diameter of 0.86mm.

[0051] The medium-drawn steel wire undergoes heat treatment-alkali and acid washing to remove scale and clean the surface-copper plating and galvanizing-heat diffusion into brass-surface cleaning treatment-saponification treatment to become semi-finished yellow wire. Yellow silk is controlled according to the following standards:

Abstract

The invention discloses a composite deformation type high-strength sawing wire and a manufacturing method thereof. The sawing wire is of a structure that edge-folding deformation exists in a single plane and bending deformation exists in three-dimensional space. In the single plane, the sawing wire is bent into a wavy structure, and crest heights of a composite deformed wire are identical within the spatial range. The composite deformation type high-strength sawing wire and the manufacturing method thereof solve the problems existing in traditional multi-wire cutting. The sawing wire has a periodical deformation feature, multiple inner spatial structures are formed by the deformed wire in each period, and then more mortar can be brought in when the sawing wire is used; meanwhile, auxiliary blades formed by edge-folding and bending deformation can play a role in chip removal, and the sawing wire is especially good at cutting hard and brittle materials such as solar silicon wafers, quartz, silicon ingots, ceramics, sapphire, gallium arsenide and stone.

Description

technical field [0001] The invention relates to a compound deformed high-strength cutting steel wire and a manufacturing method thereof, which are used for cutting materials such as silicon chips, silicon anchors, quartz, gallium arsenide, and silicon carbide. Background technique [0002] Since the beginning of the 21st century, the electronics industry, communications, and clean energy have developed rapidly, especially the rapid development and application of solar cells in the field of clean energy, which has brought about a blowout development in the field of hard materials. Especially the cutting of monocrystalline silicon and polycrystalline silicon anchors (sheets). The total demand for cutting wire has exceeded 100,000 tons. The cutting method adopts multi-line cutting. Its cutting process and characteristics are as follows: [0003] The main cutting device is composed of a pay-off wheel, a thread-passing wheel, a tension stabilization system, a guide wheel groov...
