Two new grinders ordered by Henan Jiyuan will be installed in Jiyuan, Henan province, China.
They will process 150-mm square special steel billets up to 12 m long in full skin and spot/pattern grinding modes.
Both grinders will be equipped with the highly reliable NGS16 Danieli belt-driven spindle, driven by 160-kW main motors and Danieli original Hi-Grind removal control system, to ensure an output ranging from 70,000 to 90,000 tpy.
Manufactured and tested at Danieli China workshops in Changsu, the new grinders are scheduled to be fully operational by early 2021.
This new order follows the supply for two grinding units which have been operating in the same plant since 2015.
Danieli Centro Maskin HiGrind technology guarantees the strictest tolerances and best surface quality
Featuring Danieli Centro Maskin “Cast-t-Grind technology”, it processes hot slabs up to 800°C.
After commissioning and start up, the new innovative plant combining Danieli Centro Maskin SuperGrinders technology and the IntelliGrind DDS automatic defects detection system is in operation
Tube eccentricity is an extremely critical control parameter for copper tubes since the greater the eccentricity of the tube, the greater the amount of copper material consumed during manufacturing. Because of the very high cost of the raw material (currently about 4,300 $/ton) an improvement in eccentricity of even only 1 or 2% can provide significant financial benefits (OPEX).
