CISDI’s upgrades at Yieh Hsing’s Special Steel will boost production

CISDI is currently transforming a special steels wire-rod and bar-in-coil production line at Pingdong County in Taiwan.

The existing line dates back to 1995, when its critical equipment was imported from Germany by Yieh Hsing Co, under the E United Group in Taiwan.

CISDI is installing a new reducing and sizing mill for wire-rod rolling and BIC production units, in addition to reusing existing facilities.

Upgrades are also being made to the existing water cooling and temperature control system, the pinch roll and laying head unit, coil finishing and collection system.

A modernised, combined production line will be created for the high-speed rolling of special steel wire-rods and bars in coil. Its annual production capacity is projected to hit 450,000 tonnes - an increase of 150,000 tonnes on current production.

Steel grades produced will include quality carbon steel, structural alloy steel, free cutting steel, and austenitic, martensite and ferritic stainless steels. Product specifications will feature a diameter range of 5.5 to 20.0mm for wire-rods and 14 to 38 mm for bars in coil.

A host of CISDI’s core tech and equipment is being applied, including:

✔         NHCD standardised high-rigidity short-stress path rolling mill

✔         SRSCD standardised high-speed wire-rod reducing and sizing mill

✔         LHCD standardised large-inclination laying head

✔         WCS high-precision, closed-loop water cooling and temperature control system

✔         FHSCD standardised flying shear.
