Abstract

The invention relates to a closed electrolytic pickling machine set which comprises an inlet wire water curtain groove, at least one electrolytic pickling grooves and an outlet wire water curtain groove which are arranged in sequence along the wiring direction of a steel wire. The closed electrolytic pickling machine set is characterized in that two ends of cover plates of the electrolytic pickling grooves are provided with inlet wire sealing devices and outlet wire sealing devices respectively, the inlet wire sealing devices and the outlet wire sealing devices can be penetrated by the steel wire, and can prevent pickling solutions in the electrolytic pickling grooves from escaping from two ends; positive work grooves and negative work grooves are arranged in the electrolytic pickling grooves, the steel wire penetrates above the positive work grooves and the negative work grooves, positive plates are mounted in positive work grooves, and negative plates are mounted in the negative work grooves; and the positive work grooves and the negative work grooves are connected with a liquid outlet of an acid pump box through an acid inlet pipe respectively, and a liquid inlet of the acid pump box is communicated with the interiors of the electrolytic pickling grooves through an acid pimping pipe. The closed electrolytic pickling machine set has the advantages of being ingenious and reasonable in structure, good in sealing performance, free of pickling solution leakage, and environment friendly.

Description

technical field [0001] The invention belongs to the technical field of steel wire heat treatment-surface treatment equipment, and in particular relates to a closed electrolytic pickling unit. Background technique [0002] In the prior art, in order to improve the comprehensive performance of the steel wire, heat treatment and surface treatment are generally required for the steel wire. Generally speaking, the steel wire has to go through heat treatment, pickling, phosphating, hot water washing, boronization, saponification, drying and other processes during production, and each link has a great influence on the drawing performance of the steel wire. [0003] In the steel wire drawing production process, the quality of the phosphating film on the steel wire surface is very important, which directly affects the surface quality, mechanical performance index and mold loss in the production process of the steel wire after drawing. The lubricating phosphating film formed by phosp...
