調合模砂
英文
blended molding sand-
This paper analyzes the factors affecting the controlling precision of sand compactibility system and sets up the dynamic model of regression coefficient between sand compactibility and water content. to prevent the insufficiency or excess of sand water content, the amount of the first addition is set as 80 % of the total water addition amount. after the first water addition, we adopt ar model to predict the stable value of sand compactibility to shorten the time mixing the sand. each time we add water, the correction coefficient is introduced to adapt to the change in the composition of sand. the experiment shows that the mathematics model not only makes the water content in sand reach the best range within shorter time, but also directs how the sand composition should be adjusted, which can better conform to the actual situation
分析了影響型砂緊實率控制精度的因素,建立了型砂緊實率-水分回歸系數的動態模型.為防止型砂水分不足或過量,將第一次加水量設定為總加水量的80 .第一次加水后,對型砂緊實率穩定值採用ar模型進行預測,以縮短型砂混制時間.每次加水后,引入修正系數,以適應型砂組成的變化.實驗表明,該數學模型不僅使型砂水分含量在較短時間內達到最佳范圍,同時可指示對型砂組成進行調整,能較好地符合實際情況During the development adjustment of oil fields, an effecive adjustment and potential seeking pattern is constructed adapted to the characteristic of oil field sand body and residual oil distribution through a further recognition on the geologic characteristic
