0.25mm 0.3mm Galvanized Steel Wire

Plating before drawing process: In order to improve the performance of Galvanized Steel Wire, the process in which the Steel Wire is subjected to lead scorching, galvanizing and then drawing to the finished product is called the first plating and then drawing process. The typical process flow is: steel wire - lead quenching - galvanizing - drawing - finished steel wire. The process of first galvanizing and then drawing is the shortest process in the drawing method of galvanized steel wire, which can be used for drawing after hot-dip galvanizing or electro-galvanizing. Drawing after hot-dip galvanizing has better mechanical properties than drawing and plated steel wire first, and drawing after electro-galvanizing makes the zinc layer dense and resistant. Both can obtain a thin and uniform zinc layer, reduce zinc consumption and reduce the load of galvanizing line.
The process of drawing after middle plating: the process of drawing after middle plating is: steel wire - lead quenching - primary drawing - galvanizing - secondary drawing - finished steel wire. The characteristics of middle-plating and post-drawing are that the lead-quenched steel wire is drawn once, then galvanized, and then drawn twice to the finished product. The zinc layer of steel wire produced by middle plating and then pulling is thicker than first plating and then pulling. Hot-dip galvanizing can give high overall compressibility (from lead quenching to finished product), which is better than galvanizing and then drawing.
Mixed plating and drawing process: To produce ultra-high strength (3000 N/mm2) galvanized steel wire, a "mixed plating and drawing" process is used. The typical process flow is as follows: lead quenching—one drawing—pre-galvanizing—second drawing—final galvanizing—three drawing (dry drawing)—water tank drawing a finished steel wire. The above process can produce ultra-high-strength galvanized steel wire with a carbon content of 0.93-0.97%, a diameter of 0.26 mm, and a strength of 3921 N/mm2. The zinc layer protects and lubricates the surface of the steel wire during drawing, and no wire breakage occurs during drawing

The main processes of steel wire production include raw material selection, scale removal, drying, coating treatment, heat treatment, wire drawing, coating treatment, etc.
Removing iron oxide scale refers to the removal of iron oxide scale on the surface of wire rod or intermediate wire billet. The purpose is to prevent iron oxide scale from damaging the surface of die and steel wire during drawing, to prepare good surface conditions for subsequent coating or coating treatment, and to reduce friction during drawing. Reduce pulling force. There are two types of methods for removing iron oxide scale: chemical method and mechanical method, see chemical descaling of wire rod and mechanical descaling of wire rod.

Galvanized steel wire is used for prestressed concrete structure reinforced, such as large-span bridges on railway and highway, overhead crane beam, rock-soil anchoring Project, multi- storey industrial buildings, stadiums, coal mines and etc.
