Butt Welders

Run your thumb along a coil of 6.5 mm hot-rolled wire rod straight from the mill and you will feel it: a grey, brittle film that flakes under a fingernail. That film is mill scal...

When a 5.5 mm medium-carbon rod leaves the hot rolling mill, its surface carries an oxide scale layer typically 10 to 30 microns thick. Pull that rod straight into a drawing die ...

A wire mill in Taichung ran a 5.5 mm low-carbon rod through a new drawing machine without any surface treatment and lost two dies in the first hour. The die cones showed deep lon...

Wire drawing plants processing 12 mm high-carbon rod at 8 tons per hour cannot tolerate scale on the incoming surface. Oxide from the hot rolling mill abrades tungsten carbide di...

A coil of hot-rolled steel wire rod carries up to 20 kilograms of mill scale per tonne. Feed that scale into a drawing die and it behaves like loose grit: die wear accelerates, t...
