Problem in drawing electro galvanized wire


Q. Dear friends,

I have a unit of electro galvanising of mild steel wire. I have a 16 die machine wherein the wire of 16 gauge (1.60 mm) is directly drawn to 26 gauge (0.45 mm). At present I am drawing electro galvanising wire in that 16 die machine using compressed carbide dies. This dies get crashed or oval shape due to some reason. At present I am drawing it in soap water. I am only giving 0.50 mm reduction on every die but the dies get crushed or the r.m. goes oval or the wire breaks due to this reason. Can someone suggest how to solve this problem of wire drawing? If possible, than do write to me or contact me.

A. First, I recommend oil or animal fat based water soluble lube. Second, you need to know what percentage reduction the machine is, that is a percentage of the area not a fixed dimension. We do thousands of pounds a day. I also recommend final 4 dies be composite diamond for a good finish.
