Problems solved by technology

[0004] Due to the inherent defects of rolling, nickel-iron products have irreparable defects in the drawing process, such as peeling, burrs, oxide layer fracture, etc., and the apparent quality is restricted
[0005] Limited to the requirements of environmental protection, the implementation of traditional pickling process has the problems of large investment and low metal recovery rate. The pickling water is large, and the discharged water will contain harmful elements such as hexavalent Cr and Ni ions. Effective treatment will bring expensive costs. In addition, the "yellow smoke" and the blasting sound produced by the alkali explosion in pickling cannot be eliminated, causing great pollution to the environment

Embodiment

[0022] 1) Raw material: φ8.0-φ12.0mm nickel alloy wire.

[0023] 2) Pay-off: Put the nickel alloy wire to be processed on the pay-off rack, and then place the pay-off rack on the pay-off reel.

[0024] 3) Threading: Pass the wire rod through each guide wheel, straightening wheel, tripod, cutter head, abrasive belt wheel, and take-up wheel in turn.

[0025] 4) Tool adjustment and centering: adjust the center position of the tripod to align with the center of the turning tool, ensure that the wire passes through the center of the cutter head horizontally, lock the tripod bracket, and adjust the feed rate of the cutter head to ensure that there is no oxide residue on the surface of the wire after peeling. .

[0026] 5) Polishing: Start the polishing machine to polish the surface of the stripped wire rod. Four abrasive belts are used. The abrasive belt disc adopts a planetary rotation polishing method. While revolving around the wire to be processed, the abrasive belt itself rota...

Abstract

The invention discloses a surface processing method of a nickel alloy wire, and relates to a surface processing method used for removing oxidation scales of the nickel alloy wire and polishing the nickel alloy wire. The surface processing method of the nickel alloy wire is characterized in that in the processing process of the nickel alloy wire, the oxidation scales and surface quality defects of the nickel alloy wire are removed with a hard alloy turning tool, and a planet type sanding belt disc is rotated to rub the surface of a peeled nickel alloy wire, so that the surface of the nickel alloy wire is polished. Compared with a traditional acid pickling method, the surface processing method of the nickel alloy wire has the advantages that the oxidation scales and surface defects are cleaned up thoroughly, the metal recovery rate is high, the surface quality of the wire is good, a processing process is simple, production cost is low, and the production environment is improved.

Description

technical field [0001] The invention discloses a surface treatment method for a nickel alloy wire rod, relating to a surface treatment method for removing scale and polishing the nickel alloy wire rod. technical background [0002] In the process of nickel and nickel-based alloy wire, the removal of scale after annealing is a key issue. The high-pressure water blasting method can get rid of the traditional pickling process with low recovery rate and serious environmental pollution. However, in the actual production process and results, the sandblasting descaling process has a high failure rate of equipment and low production efficiency for some nickel alloy steel types. The effect of scale removal is not ideal, which has become a bottleneck that seriously restricts production. When the sandblasting and descaling process cannot meet the production needs, the nickel alloy wire rod descaling still needs to be carried out by the traditional pickling process, which increases the...
