Metallurgical investigation of different causes of center bursting led to wire breakage during production

(in lingua inglese)

The wire drawing process is quite simple in concept. The wire rod before drawing mechanical descaling or pickling was carried out according to the requirements of customer or grades .The wire then fit through the die; the wire is then pulled through successive die maintaining proper lubrication and cooling of die. Each stage of drawing consists of a drum and a die (which help in drawing). The speed of each drum is maintained at higher speed than the previous one. Generally calcium soap is use as lubricant. The drum helps to decrease the temperature which rises during drawing operations thus proper cooling of die is required. And the drum also acts a buffer for storage of wire.
