最新のOptiLoadマルチニップカレンダについて: 生産性および紙品質の向上

摘要

The paper and board markets of today are frequently unpredictable and fast-moving. When investing in a new paper line, the papermaker should be prepared to deal with changing demand outlooks and market conditions. Therefore, the papermaking process needs to be flexible. In the past, calenders were designed to produce one paper grade with specific production parameters. In the recent years, however, calendering equipment has been developed to be more versatile. Today's OptiLoad multinip calender is the result of decades of evolution, utilizing all the engineering experience gained from earlier deliveries. This article summarizes the state-of-the-art in multinip calendering and gives hints for the future. The calendering features reviewed here are also applicable to calender rebuilds, such as supercalender upgrades.%今日の紙•板紙市場動向はめまぐるしい変化を遂げており，予測困難なことも多い.したがって新設の製紙ラインを計画•投資する場合，需要見通しおよび市場環境の変化に対応可能な配慮をこれまで以上にしなければならず，抄紙工程には柔軟性が求められる.
