Abstract

The invention relates to a steel wire sealing type smokeless pickling line. The pickling line comprises a wire inlet water curtain groove, at least one pickling groove and a wire outlet water curtain groove, wherein the wire inlet water curtain groove, the pickling groove and the wire outlet water curtain groove are arranged sequentially along a steel wire routing direction. The pickling line is characterized in that a wire inlet sealing device and a wire outlet sealing device are respectively arranged at two ends of the cover plate of the pickling groove, steel wires can penetrate through the wire inlet sealing device and the wire outlet sealing device, the wire inlet sealing device and the wire outlet sealing device can prevent pickling solutions in the pickling groove from volatilizing from two ends, a pickling working groove is arranged inside the pickling groove, a pickling solution chamber is arranged at the rear end of the pickling working groove and connected with a liquid outlet of a steam heating acid pump box through an acid inlet pipe, a liquid inlet of the steam heating acid pump box is communicated with the interior of the pickling groove through an acid drawing pipe, and the upper surface of the pickling working groove is provided with a plurality of turbulent flow retaining bars. The pickling line is ingenious and reasonable in structure, steel wires can work stably in the pickling solutions, a jumping phenomenon cannot occur, the cleaning effect is good, the acid consumption is low, and the pickling line is environment-friendly and beneficial to improvement of product quality.

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 steel wire closed smokeless 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 ...
