By cooperating with some domestic companies and analyzing the various factors caused the post-pass work preface fracture of wire of the high-carbon steel wire dry wire drawing craft, this dissertation puts forward a new fixed amount judging method and adopts computer simulation methods to predict and control the production situation.

It is pointed out that the fine stainless steel wire produced by melting drawing can only be used to some realms having not high requirements because of its section being shaped;the fine stainless steel wires produced by clustered drawing method have not uniform shape,uniformity and precision are worse,and the length of the fine wire is limited;the single wire drawing is.
