Embodiment 1

[0026] The method for electroplating and repairing the nickel-plated combined crystallizer narrow plate with Ni-Co-W alloy electroplating solution is carried out according to the following steps:

[0027] The first step: configure the electrolyte

[0028] At room temperature, pour deionized water into the acid-resistant barrel, measure the calculated amount of sulfuric acid (the main component is hydrochloric acid, concentration 20% to 30%), sulfuric acid (98%), and add sulfuric acid and sulfuric acid along the wall of the acid-resistant barrel Add it to deionized water, stir while adding, the composition of the electrolyte is kokie acid: sulfuric acid: water = 1:1:6, let it cool for a certain period of time, and set it aside;

[0029] The second step: narrow plate rough machining

[0030] 1. Connect the tooling to the threaded hole on the back of the narrow plate with bolts, and then install and fix it on the machine table as a whole;

[0031] 2. Set the processing paramete...

Embodiment 2

[0043] The steps of this embodiment are the same as those of Embodiment 1, and the specific parameters are shown in Table 1.

Embodiment 3

[0045] The steps of this embodiment are the same as those of Embodiment 1, and the specific parameters are shown in Table 1.

[0047] Specific parameters

[0048]

[0049] The method of the present invention carries out electroplating repair to the narrow copper plate of the crystallizer, and the working surface and the side of the narrow plate after electroplating are processed by the machine tool, and the phenomenon of peeling and shedding of the coating does not occur, and the effect of using the narrow plate on the line is the same as that of the previous coating structure. The use effect is the same, even better, and fully meets the production requirements.

Abstract

The invention relates to a method for using Ni-Co-W alloy electroplate liquid to repair a nickel-plated combined crystallizer narrow plate in an electroplating manner and belongs to the technical field of electroplating. The method includes the steps of firstly, preparing electrolyte; secondly, rough machining the narrow plate; thirdly, cleaning the narrow plate; fourthly, electrolyzing the narrow plate; fifthly, electroplating the crystallizer narrow plate. The method has the advantages that the method in novel in concept and well-organized in sequence; nickel alloy is plated on the nickel layer of the lateral edge of the crystallizer narrow plate, electroplating time of the narrow plate can be reduced from five days to three days, lateral edge machining amount is reduced, consumption of cobalt, nickel and power is reduced, work efficiency is increased, and production cost is lowered; wear resistance of the plated layer is increased by using the Ni-Co-W alloy electroplate liquid, and the service life of a crystallizer is prolonged.

Description

technical field [0001] The invention belongs to the technical field of electroplating, and in particular relates to an electroplating repair method for a combined crystallizer narrow plate. Background technique [0002] The combined crystallizer is composed of wide plate, narrow plate and narrow plate clamping device, and is used for continuous casting of square and flat ingots. Since the continuous casting machine requires a large amount of steel in a single pass, a fast casting speed, and a large wear of the mold coating, when the coating on the working surface is less than the set value, the coating on the working surface of the copper plate of the mold needs to be repaired. At present, the commonly used repair method for the narrow plate of the crystallizer is to firstly process the working surface and assembly surface of the narrow plate to 0.1mm below the coating, that is, process away the 0.1mm copper substrate to ensure that all the coating on the surface of the work...
