Problems solved by technology

However, due to the high price of copper metal, the process of electroplating and copper-zinc melting requires a lot of electric energy, and the relative cost is relatively high; at the same time, due to the inertia of copper, it takes multiple adsorptions to form a coating on the surface of the steel wire, so that the steel wire is soaked in the electroplating solution For a large amount of time, the total amount of copper plating liquid during assembly line production is relatively large, which increases a lot of production costs
At the same time, in the wire cutting process of solar electromagnetic sheets, semiconductor wafers and semi-ceramic sheets, the coating on the surface of the steel wire does not actually play any role, and a large amount of precious metals are wasted. Therefore, a new coating line and a new coating line can be designed. production process to solve the above-mentioned deficiencies

Embodiment 1

[0014] The production process of galvanized cutting wire is to heat the high-carbon steel material with a carbon content of 0.7% to 950°C in a heat treatment furnace to obtain a uniform austenite structure, and then rapidly cool it to 560°C to keep it warm to obtain ultra-fine wire that is easy to draw. Pearlite structure, heating and holding time vary with the diameter of the wire, and then the surface oxide layer is removed by the surface treatment device, and then electroplated with 5g / kg zinc on the surface of the steel wire by the electroplating equipment, and then transferred to the wire drawing equipment for drawing Pulled into a φ0.10mm cutting wire.

Embodiment 2

[0016] The production process of galvanized cutting wire is to heat the high-carbon steel material with a carbon content of 0.85% to 1000°C in a heat treatment furnace to obtain a uniform austenite structure, and then rapidly cool it to 600°C to keep it warm to obtain ultra-fine wire that is easy to draw. The pearlite structure, heating and holding time vary with the diameter of the wire, and then the surface oxide layer is removed by the surface treatment device, and then electroplated with 10g / kg zinc on the surface of the steel wire by the electroplating equipment, and then transferred to the wire drawing equipment for drawing Pulled into a φ0.12mm cutting wire.

Embodiment 3

[0018] The production process of galvanized cutting wire is to heat the high-carbon steel material with a carbon content of 0.95% to 1050°C in a heat treatment furnace to obtain a uniform austenite structure, and then rapidly cool it to 640°C to keep it warm to obtain ultra-fine wire that is easy to draw. The pearlite structure, heating and holding time vary with the diameter of the wire, and then the surface oxide layer is removed by the surface treatment device, and then electroplated with 13g / kg zinc on the surface of the steel wire by the electroplating equipment, and then transferred to the wire drawing equipment for drawing Pulled into a φ0.14mm cutting wire.

Description

technical field [0001] The invention relates to equipment for producing galvanized cutting wires, and also relates to a production process for galvanized cutting wires, which belongs to the fields of electrochemistry, metal plasticity and semiconductor sawing processing. Background technique [0002] Enterprises engaged in the production of cutting steel wire mostly adopt the traditional technology of wire for automobile tires, that is, first electroplate a certain amount of copper on the surface of the steel wire to obtain the required structure, then plate a certain amount of zinc, and then melt the copper and zinc under a certain high temperature condition. , to produce a surface brass coating suitable for drawing, and then drawn to the required size in the wire drawing machine. However, due to the high price of copper metal, the process of electroplating and copper-zinc melting requires a lot of electric energy, and the relative cost is relatively high; at the same time,...
