Moorim achieves efficient, non-stop production - Part II

December 02, 2012 - 22:47

BRUSSELS, Dec. 3, 2012 (RISI) -The commissioning of the Moorim Paper Group's DongHae PM 1 saw the launch of the first non-stop production line in South Korea. The resource-saving mill concept allows for an integrated production line from pulp to finished paper.Click hereto read Part I.

Services ensure plant efficiency

Voith Paper will provide Moorim with support in the first two years after startup in the form of a service team available six days a week. The Advanced Production Support team will optimize the plant and coordinate and supervise all activities necessary for a stable operation of PM 1. The team will also train the machine operators and support and advise the customer in hydraulics, mechanical systems and the automation of the paper machine, offline coater and Janus calenders.

Moreover, a Total Roll Management (TRM) contract, that will run for an initial period of five years, provides a fully inclusive "worry-free" roll environment. The TRM covers all rolls and the complete roll environment: It includes covers and coatings, roll servicing, drying cylinder coatings, grinding and doctor blades. This maximizes roll availability, increases machine efficiency and keeps maintenance costs to a minimum. Improving the roll running properties is an integral part of the TRM concept. This is why it is vital to focus not just on the rolls themselves but the entire roll environment - from clothing to doctors or machine. All of this guarantees optimum paper production.

The locally produced liquid pulp is pumped directly to PM 1

Moorim will use SØNAR, Voith's proprietary roll management software, to gather data about all its rolls. Service reports for every roll, grinding intervals, running times, operating logs and special features of each roll are stored in the software's databases. These data help Voith's roll service specialists to identify and implement optimization potentials. As a result, it is possible to significantly reduce costs for maintenance in some areas.

Voith and Moorim are working together to further enhance the roll inventory and improve running properties. By appointing Voith to manage its roll inventory, Moorim can concentrate fully on the production of paper. Voith ensures optimum care of the rolls through its experienced service specialists.

The close cooperation of all those involved assured an excellent startup for DongHae PM 1

The scope of supply includes the entire paper machine, offline coater and two Janus calenders. The stock preparation unit features two IntensaPulper IP-Vs, which ensure reliable pulping of the highest quality and energy efficiency courtesy of the innovative technology used. The VariPlus and VariFlex winders also help to provide maximum flexibility when producing a wide range of roll widths in optimum winding quality. Voith Paper also supplied all clothing, roll covers and SkyLine doctor blades for machine startup. In addition, it undertook the complete basic engineering for the production line as well as assembly and start-up supervision. To ensure ideal paper quality, Moorim Paper opted for a quality control system with a total of nine scanners. These include, for example, two Voith LSC QuantumSens optical caliper sensors for non-contacting measurement of paper thickness. In addition, Voith Paper supplied the process control system for the stock preparation unit and the ancillary systems, and the machine control system. A large number of built-in actuators and the machinery and technology monitoring rounds off the package.

Excellent cooperation equals success

One of the great challenges of this project was the large number of interfaces between the various suppliers. All participants worked in a spirit of partnership. In particular, it was through close cooperation with Voith Paper's representative in South Korea, that the common objective -- the successful startup of the production line -- was realized. J. K. Choi, president of Voith Paper Korea Representative, explains: "The excellent and friendly cooperation was the basis for the outstanding success of this project."
