Magnetic Detector


Magnetic Detector

This equipment is used to detect hair cracks on the surface of a hot-rolled round bar through magnetic particle testing and thereby to remove the cracks through grinding in the next process.

Testing range of hot-rolled round bar : 25~90mm x 4,000~8,000mm

Heat Treatment equipment


Heat treatment(annealing furnace)

The equipment is used to heat high-carbon steel or alloy steel at 600~700 oC first and then cool off the material slowly in order to make the internal structure even, remove stress, and improve the quality of material.

Equipment spec. : 20 ton/Charge Car Type Annealing Furance

Wire Rod Straightener


Wire rod straightener

A domestic or imported wire rod is injected to the equipment that produces a hot-rolled straight round bar.

Production size : 16~36mm round bar

Production capa. : 300 tond/month
