Steel wire sealing type smokeless pickling line

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 present invention belongs to the field of steel wire thermal treatment-surface treatment equipment technology, which is specifically involved in a steel wire closed smoke non-smoke pickle unit. Background technique [0002] In existing technologies, in order to improve the comprehensive performance of steel wires, the wire is usually required for heat treatment and surface treatment.Generally speaking, the steel wire should be treated with heat treatment, pickling, phosphorification, hot water washing, boron, saponification, drying and other processes during production. Each link has a great impact on the pulling performance of the steel wire. [0003] During the production process of steel wire pulling, the quality of the phosphorum film on the surface of the wire is very important. It directly affects the surface quality, mechanical performance indicators and the mold consumption in the production process.The lubricating film generated by phosphorific...
