The application of Vacon frequency converters in the pulp industry

about 200 Vacon frequency converters were used in Imatra pulp mill project in 2001

at this moment, the largest project in Finnish wood processing industry, the 2001imatra pulp production line, marks the construction of a new production line in Imatra pulp mill in kaokupaa, Southeast Finland. Vacon will provide about 200 frequency converters for various purposes to the Stora Enso PLC branch, which is the world's largest paper and plate manufacturer. This huge project consists of several small projects, involving about 150 contractors. It was started in 1999 and completed in 2002

2001imatra's pulp production line project was launched due to the following needs:

a. adapt to modernization and improve the production capacity of its slicing process

b. build the third new fiber production line

c. suitable for No.2 fiber production line

d. suitable for different kinds of purposes in power plants

Both MDI and TDI are raw materials for polyurethane production. E. build a new drying line and transform the papermaking processing line of tainiokoshi

the annual output of the new production line will be 500000 tons of birch pulp. The pulp drying line is expected to produce 1000 tons of chemical pulp per day. The annual production capacity of timber will be 35million cubic meters. This will fully meet the needs of wood pulp used in papermaking and plate processing. And create good conditions for the future development of our factory and increase the output of plates. The new fiber production line is expected to run in early April 2001. In addition, the plate control system used to adapt to the existing fiber production line will be launched in October 2002. The budget of the whole project is 365million euros

all main process equipment are controlled by Vacon frequency converter, including pumps, fans, conveyors, slicers and paper reelers. The power range of Vacon frequency converter in this project is 0.75kw-710kw

the successful application of vasa in the pulp industry

although the business of the paper industry is very prosperous at the moment, in recent years, the market is facing many changes that reduce profits: including the increase of customer requirements, the reduction of orders, etc. Because most pulp and paper producers cannot afford higher costs, they must find other ways to reduce costs and improve efficiency. The most reasonable way to achieve this goal is to save energy in the production process. Because the Vacon frequency converter can adjust the speed of the motor steplessly in the pulp production process, it can reduce a lot of energy consumption and improve the processing technology. In fact, the variable frequency speed regulation system can also protect the machine and avoid unnecessary impact on electricity during startup. To sum up, the investment will return in the short term. This process requires that the accuracy and service life of the sensor will be affected if the accuracy of the strain gauge is not high, or the aging resistance of the glue used to fix the strain gauge is not good, or the material of the sensor is not good. Before molding, the five-star principle plays an important role

when a large company in the world is looking for suppliers for larger projects, its expectations and requirements must be very high, First of all, the most important thing is to have reliable equipment and convenient services. Vasa's five-star standard and its business policy play an important role in Stora Enso's selection of power plant suppliers
