Изобретение относитс к прокатному производству, в частности к способам намотки холоднокатаной полосы на барабан моталки.The invention relates to rolling production, in particular, to methods for winding cold-rolled strip on a winder drum.
Цель изобретени - повьшение качества наматьшаемой полосы.The purpose of the invention is to increase the quality of the strip.
На чертеже показан график зависимости распределени значени величины нат жени по ширине полосыThe drawing shows a graph of the distribution of the magnitude of the tension value across the strip width.
В соответствии с предлагаемым способом намотки полосы при намотке измен ют нат жение полосы по ее ширине, при этом изменение производ т по выражениюIn accordance with the proposed method of winding the strip during winding, the tension of the strip along its width is changed, and the change is made according to the expression
rS; l,(i-r(i-i)jL . rS; l, (i-r (i-i) jL.
.где и;. . - среднее значение величины нат жени полосы на i -м виткеJ. where and; . - the average value of the tension of the band at the i th turn
Jcp(i-i) среднее значение величины нат жени полосы на (i-l)-M витке;Jcp (i-i) is the average value of the tension of the band on the (i-l) -M loop;
19201. 219201. 2
(j, , - значение величины нат жени полосы в j.-й точке (1-1)-го витка.(j,, is the value of the tension value of the strip at the j.th point (1-1) of the th turn.
При намотке полосы по предлагае- 5 мому способу повышенные локальные межвитковые давлени на одном витке компенсируютс понижением локальных межвитковьгх давлений на следующем витке за счет перераспределени fO величины значений нат жени полосы по ширине обратно пропорционально распределению величин значений нат жени на предыдущем витке.When the strip is winding according to the proposed method, the increased local inter-turn pressure on one turn is compensated by lowering the local turn-over pressure on the next turn due to the redistribution of fO values of the band tension values across the width of the previous turn.
f5 На. чертеже графиком 1 обозначена крива распределени величин значений нат жени полосы на первом витке; , а графиком 2 - упом нута крива на втором витке.f5 on. Drawing 1 shows the distribution curve of the values of the band tension values on the first turn; and schedule 2 is the mentioned curve on the second turn.
20 Технико-экономический эффект от внедрени предлагаемого изобретени обеспечиваетс повышением качества наматываемой полосы по сравнению с известным.20 The technical and economic effect from the implementation of the proposed invention is ensured by an increase in the quality of the coiled strip in comparison with the known one.
