SU837985A1 - Method of zinc-plating of infinitely joined wire lattice interweavings - Google Patents

Abstract

Mats, with wires welded at right angles to each other and to the edge of the breadth, are dip galvanised in Zn baths, the mats passing out of the baths at angles across and along the direction of travel. The process can be operated continuously in all stages, the Zn draining along the wires, and gives a good, uniform surface quality. The throughput can be increased and the power and chemical consumption reduced.

Description

(54) METHOD OF ZINCING INFINITELY CONNECTED WIRE MECHANICAL INTERLACE

one

The invention relates to a method of galvanizing infinitely connected wire lattice weaves with wire welded smoothly to each other and a tape edge.

There is a known method of hot-dip galvanized wire sieves by drawing pre-fluxed grids through a bath of molten zinc and removing it at an angle along the direction of movement and then removing excess zinc 1.

However, galvanizing in this method of infinitely connected wire lattice weaves with welded right to each other and a tape edge with a wire that underwent spot welding during the manufacturing process, does not allow to provide high-quality coating due to the formation of icicles and insufficient flow of zinc welding sites, as well as E1conomic consumption of chemicals and metal coating.

The purpose of the invention is to improve the quality of galvanizing wire lattice weaves with a gifted right along each other and with a ribbon edge.

2

In order to achieve this goal, the immersion and extraction of infinitely connected wire lattice weaves from the bath are carried out simultaneously and at an acute angle across the direction of movement, at which the angle along the direction of movement is 20 ° -45 °.
