Description
Technical field
The present invention relates to steel wire process fields, and in particular to a kind of wire galvanization method.
Background technique
Mainly there are two kinds in the zinc-coated wire that metal material processing technical field is produced or used both at home and abroad at present: one is
Cold galvanizing steel wire, one is hot-dip galvanizing steel wires.Hot galvanizing is developed by more ancient hot-dipping method, has there is 107
10 years history.However, hot dip Zn Cr coating is to have obtained in the late three decades with the rapid development of cold-strip steel on a large scale
Development, the production process of heat zinc coating plate specifically include that raw sheet preparation → treatment before plating → hot-dip → plating posttreatment → at product examine
It tests.Treatment before plating is generally used the method that lead washes rear pickling in the prior art, and lead bath is the pass in medium high carbon Production for Steel Wire
Key process, steel wire obtains Soxhlet body tissue by lead bath, such to organize the drawing limit with higher, can obtain after steel wire drawing
Good comprehensive mechanical property is obtained, it is disadvantageous in that steel wire lead is easy to hang lead after washing, after galvanized wire hangs lead, the quilt in pickling
The iron scale of lead covering is not allowed to be readily removable, and can not be formed on its surface the phosphating coat of continuous densification, and when drawing, lead exists quickly
Die entrance accumulation, is that lubricant can not be brought into mold, and phosphating coat is scraped, risen in a mold plus iron scale
" abrasive material " effect, mold are worn quickly, cause steel wire diameter poor, simultaneously because insufficient lubrication, the drawing of steel wire in a mold
Temperature steeply rises, and influences the twisting property of steel wire, while it is existing to be also easy to occur the undergauge that small dimension steel wire is in wet drawing
As.
