The Taper Drill Rod Production Line mainly produces hollow steel for rock drilling, light rock drilling machine with brazing tools, drilling tools for drilling cars, drilling tools for drilling drill and other products, it also can produce small seamless thick wall pipe. It has high yield and wide range of products. The Taper Drill Rod Production Line especially has the six-roll hot rolling technology, which can produce compressive stress on the surface of hexagonal hollow steel and improve the surface fatigue resistance of products. The Taper Drill Rod Production Line is mainly composed of heating furnace, piercing machine, reducing machine, six-high rolling mill, straightening machine and collection equipment.
