- 摘要：
- The present invention relates to improvement in a method for estimating a setting value of a dryer steam pressure after papermaking exchange according to simulation in a papermaking machine and an apparatus therefor, where a steam pressure setting value after papermaking exchange is estimated accurately by determining an in-hood air dry-bulb temperature on the basis of a difference between an in-drum steam temperature which has been just measured and an initial value of an in-drum steam temperature, thereby reducing a papermaking exchange time as well as reducing broke and improving the rate of operation.
