A CISDI-supplied modular Finishing Mill, the first of its kind in China, is operating smoothly at a high-speed wire-rod rolling line at Pangang Changcheng Special Steel.

All production indicators have hit design requirements.

Its successful implementation expands the company’s product portfolio, while upgrading China’s core equipment.

It brings CISDI’s modular rolling mill into the advanced manufacturing sector for the high-speed rolling of special steels.

The mill replaced a BGV finishing mill, featuring a transformation from original centralised control to modular control, for the highest-grade special steels wire-rod rolling line.

CISDI took technological leadership for the high-speed rolling area and supplied four CDMC250 modular mills, hydraulic and lubrication systems, electric drive and basic automation system and carried out technical assistance.

Partnering with the client and the construction company, CISDI’s team supported the equipment installation and cold testing in a tight, 25-day schedule.

The first hot testing was the successful single pass of a 13.5-millimetre dia. wire rod. The mill has since been operating stably, producing multiple specifications from 6mm, 7.0mm and 7.5mm to 11.0mm and 13.5mm. All mass production achieved performance indicators.

An exemplary achievement for a mill transformation of this type, CISDI’s team focussed on deep integration through the development, design, manufacturing and commissioning procedures and implemented strict full-process quality control.

Fact File:

Pangang Changcheng Special Steel is China’s major high-end, special metal products base. Its products are used by national defence military, aerospace and high-end equipment manufacturing sectors.

The high-speed wire-rod rolling line featuring CISDI’s modular Finishing Mill is designated to produce complicated steel grades and specifications.

Its main product grades are high-temperature alloys, titanium steel and titanium alloys, bearing steel and stainless steel, all of which have to meet very high accuracy and surface quality standards.

China’s first modular Finishing Mill is now operational at Pangang Changcheng Special Steel’s high-speed wire-rod rolling line. It was supplied by CISDI.
