Walsin Lihwa Corporation has placed an order with Friedrich KOCKS GmbH & Co KG for a Reducing Block 500++/4, continuing the successful cooperation.
Walsin Lihwa Corporation was founded in 1966. At that time the company was a manufacturer of power wire and communication cable at inception. Today Walsin Lihwa has become also a leading manufacturer of specialty steel not only in the Greater China region. It has further successfully expanded into the technology industry and become an international enterprise with real estate operations. The company has around 4000 employees and a total of 14 manufacturing plants in Taiwan and Mainland China, as well as in Malaysia, Indonesia and the USA.
The Corporation has a long history with KOCKS, having installed the very first KOCKS Reducing & Sizing Block with one input drive shaft (RSB® 370/10) already in 1991 as well as a 500 Intermediate Block. The continuation of the successful collaboration highlights KOCKS’ reliability as a partner and recognizes the superiority of the renowned KOCKS 3-roll technology.
The new KOCKS Reducing Block with 4 stand positions is to be installed in the roughing train of the wire rod and bar mill in Yenshui, Tainan, in southern Taiwan. This mill is specialized in the production of stainless steel and specialty steel grades with a capacity of approximately 300,000 tons per year.
The RB 500++/4 will be located between the planetary HRM (High Reduction Mill) and the existing KOCKS 500 Intermediate Block. Limited space availability in the installation area required a detailed investigation and an advanced implementation plan in order to integrate the block and minimize the required shutdown time of the mill.
With the implementation of the new Reducing Block, it will be possible for Walsin Lihwa to optimize the overall reduction in the HRM according to the various material grades. With the additional reduction capability on an overall length of only approx. 5m of the 3-roll Reducing Block the rolling process can be flexibly harmonized for new and advanced special steel grades.
Furthermore, larger billets can be used after the revamping which leads to higher productivity, higher yield and subsequently improved mill economy which finally assures a quick return of investment.
“We are so happy to continue our successful cooperation with KOCKS also for the roughing mill project. Thanks to the project team for giving us full support and highest attention.” Tain-Rong Chen (Senior General Manager) WALSIN LIHWA, TAINAN
