VACON变频器系统在纸浆行业中的应用名不虚传

此刻，在芬兰木材加工业这个最大的项目，即2001Imatra 的纸浆生产线，标志着一个新的生产线将在位于芬兰东南部的Kaokupaa 的Imatra纸浆生产厂建造。VACON将为该Stora Enso Plc的分厂提供适用于各种不同用途的变频器200台左右，此分厂是全球规模最大的纸业和板材生产商。此巨大项目中，由好几个小的项目组成，其中涉及到大约150个承包商，将于1999年动工2002年竣工。

2001Imatra 的纸浆生产线项目的启动是由于下述的需要A：适应现代化以及提高其切片工艺的生产能力，B：建造第三条新的纤维生产线，C：适应二号纤维生产线，D：适用于电力发电厂的不同种类的各种用途，E：建造一条新的烘干线和Tainiokoshi的造纸加工线进行改造。新生产线的年产量将为50万吨的桦木纸浆。纸浆烘干线预计每天的产量为1000吨化学纸浆。木材的年生产能力将为3500万立方米。这将充分满足此厂用于造纸和板材加工的木浆需要。并且为本厂的未来发展以及增加板材产量创造良好的条件。这条新的纤维生产线预计将于2001年4月初运行，另外，用于适应现存的纤维生产线的板材控制系统于2002年10月启动。整个项目的预算为36，500万欧元。

所有主要的工艺设备都由VACON变频器控制，其中主要包括：泵、风机、输送机、切片机和卷纸机，此项目中VACON变频器的功率范围为0.75kW—710kW。

瓦萨在纸浆业中的成功应用
尽管造纸行业的生意此刻十分兴隆，但它最近几年该市场正面临着利润降低的诸多变化：这包括顾客要求的增加、定单的减少等。因为多数纸浆和纸的生产商无法承担较高的成本，他们必须寻找其它的方法以减少开支提高效益。达到此目标最合理的方法就是在生产过程中节省能源。由于VACON变频器可以对纸浆生产过程中电机进行无级调速，从而减少大量能耗，并使加工工艺得到改善。事实上，变频调速系统还可以保护机器以及避免启动时对电网的不必要冲击。综上所述，该投资将在短期内得到回报。

五星级原则发挥着重要作用
当全球某家大公司在寻求较大项目的供应商时，期望和要求肯定是很高的，首先最重要的是要具备可靠的设备以及灵便的服务。瓦萨五星级标准和其业务方针在Stora Enso 选定动力装置供应商的时刻发挥着重要的作用。

Vacon的明星产品: CX系列变频器

顾客至上。在2001Imatra 的纸浆生产线这个较大规模的项目中，其要求之一必须定时交货以避免整个项目工期的延误。在业界，VACON定期准确交货方面享有盛名，快速而灵便的服务是我们公司的首要职责。
优秀品质。在造纸业，拥有可靠的设备是生产高品质产品的先决条件。VACON这个基于与服务网络、合作伙伴和供应商密集、长期合作的公司，在制造工艺方面的品质是毫不逊色的。
环保措施。2001Imatra 的纸浆生产线的一个目标是大大的改善Imtra以及其周围空气质量。利用VACON变频器控制电机以达到其环保的意图。不但VACON产品是环保的，其操作系统也是如此，当然，其中还包括其合作伙伴的操作系统。
优质服务。上述已证明VACON变频器是持久耐用的。然而，一旦出现故障，我们的维修工程师将随叫随到。全球的瓦萨热线电话将全年为您服务。鉴于造纸厂基本是将会全年工作，因此，由设备短时间的故障而引起的停机将可能造成一定的损失，所以优质服务是由为重要的。
不懈努力。位于Imtrad 第一家纸浆厂建立于1935年，当前的这家公司是目前欧洲最大的造纸和纸板制造企业。无论如何，对他们来说，最重要的工作是提供优质的产品和服务。同样，VACON也在为企业提供优质的控制系统解决方案这一目标不断努力着，我们相信瓦萨在不断的发展和完善。VACON进入国际市场的时间要比在IMTRAD的纸浆厂晚60年，然而，在这短短的时间里，VACON在全球变频器市场上已成了龙头企业，这对于VACON要在低压交流驱动系统占据市场主导地位这一目标将是一个不错的开头。我们深信VACON是一颗冉冉升起的新星！

VACONS IN PULP BUSINESS IS NO PULP FICTION
Nearly 200 Vacon frequency converters in the Imatra Pulp 2001 project
In the biggest project within wood processing industry in Finland at the moment, Imatra Pulp 2001, a new pulp production line will be built at the Imatra pulp mill in Kaukopää in the south east of Finland. Vacon will deliver nearly 200 frequency converters for various applications to this mill, which is a subsidiary of Stora Enso Plc, the largest manufacturer of paper and board in the world. This massive project, which consists of several subprojects and altogether involves some 150 contractors, was started in 1999 and will be completed in 2002.
The Imatra Pulp 2001 project was started in order to modernise and expand the wood debarking and chipping processes, to build a new fibre line 3, to modernise the fibre line 2, to carry out alteration work at the power station plant, to build a new pulp drying line and to reform the pulp producing line in Tainionkoski. The new production line will produce 500 000 tons birch pulp a year. The design capacity of the pulp drying line is 1000 tons of chemical pulp a day. The total annual wood handling capacity is 3.5 million cubic meters of wood. This will make the mill self-sufficient in pulp needed for their paper and board production. It will also create good conditions for the future development of the mill and for increased board production. The new fiber line is scheduled to start up in early April 2001 and the wood handling system for the existing fiber line in October 2002. The budget of the complete project is EUR 365 million.

Stora Enso's Imatra pulp mill in Kaukopää
All the main process equipment is controlled by Vacon frequency converters: pumps, fans, conveyors, debarking drum, chipper and the screw unloader. The power range of the vacons in this project is 0.75 kW CX4 - 710 kW CX6.
Vacons help making pulp business a success
Although the pulp and paper industry is booming at the moment, it has faced many changes unfavourable to profitability during the past years: requirements from the customers have increased, but the orders have reduced. Since most pulp and paper manufacturers cannot bear higher prices, they must look for other ways to cut costs and to improve profitability. The most rational way to do this is to save energy in the production process. As vacons enable stepless speed control of the motors running the pulp production process, huge amount of energy is saved and the process control is improved. The fact that the frequency converter also protects the machinery as well as the electrical grid from unnecessary strain at start-up makes their life cycle longer. The investment pays for itself in a short time.
Five-star principles play a leading role
When a worldleading company is looking for suppliers to a major-size project, expectations and requirements are high: first and foremost, dependable equipment and flexible service are fundamental. Vacon's five-star values and operational policy played a leading role when Stora Enso was choosing the drives supplier.

Vacon's star products: CX_drives
Customer comes first. In a major project such as the Imatra Pulp 2001, deliveries must be on time to avoid the delay of the whole project. Vacon has a reputation of delivering faultless products on the agreed time. Fast and flexible customer service is our priority No 1.
Superior quality. In the pulp&paper industry, dependable equipment is a prerequisite for high quality products. Superior quality also applies to the manufacturing process at Vacon, which is based on networking and on intensive, long-term co-operation with subcontractors and suppliers.
Environment-friendly approach. One goal of the Imatra Pulp 2001 project is to significantly improve the air quality in Imatra and in its environs. Using vacons to control motors complements their environment-friendly intentions. It is not only Vacon's products that are environment-friendly. Also our operation system at all stages, including our co-operation partners' operation systems, are that.
Help is always available. Vacon frequency converters have turned out to be highly durable. However, if something goes wrong, our service engineers are there for you when you need them! Vacon's worldwide on-call service is available 24 hours a day, 7 days a week, 365 days a year. Since the pulp and paper mills run basically without stopping and because haults due to even short device breakdowns easily result in high costs, this kind of service is essential.
Drive for achievement. The first pulp mill in Imatra was opened in 1935, and the present company is the biggest paper and card board manufacturing mill in Europe. For them, however, it is more important to be the best in providing products and service in their core business area. We at Vacon have a similar kind of drive for achievement and entrepreneurship. We also believe in continuous development and learning. Vacon started its international career 60 years later than the pulp mill in Imatra, but in a short time it has gained a prominent position on the worldwide frequency converter market. This is a good start in becoming one of the market leaders in customer and application specific low voltage AC drives. We believe Vacon is a rising star!
