【摘要】：針對以往連退過程中對帶鋼內(nèi)部應(yīng)力橫向分布情況無法在線預(yù)測,從而對連退過程中的跑偏、瓢曲以及帶鋼在各工藝段的板形演變無法在線預(yù)警、容易造成斷帶缺陷的問題,充分結(jié)合連退機組的設(shè)備與工藝特點,在研究了帶鋼橫向溫度差、來料板形、爐輥輥型、爐輥水平度與垂直度誤差對帶鋼內(nèi)部單元變形影響模型的基礎(chǔ)上,建立了一套適合于連退過程的帶鋼內(nèi)部張力橫向分布模型,給出了相應(yīng)的計算策略,并以寶鋼不銹鋼有限公司某連退機組為研究對象,定量分析了爐輥原始輥型、來料板形、橫向溫差以及爐輥水平度與垂直度誤差、設(shè)定張力等因素對連退過程帶鋼內(nèi)部張力橫向分布的影響,編制出了相應(yīng)的"連退機組通板過程帶鋼內(nèi)部應(yīng)力橫向分布及板形演變預(yù)報軟件",并將其應(yīng)用到生產(chǎn)實踐,取得了良好的效果,具有進一步推廣應(yīng)用的價值。
[Abstract]:In view of the fact that the transverse distribution of internal stress in strip can not be predicted on-line in the past continuous regression process, it is difficult to predict the deviation, the shape evolution of ladle and strip in the process of continuous regression, which is easy to cause the defect of broken strip. Combined fully with the equipment and technological characteristics of the continuous return unit, the influence models of the transverse temperature difference, the shape of the incoming material, the roll profile, the flatness and the perpendicularity error of the furnace roll on the deformation of the inner unit of the strip are studied. A set of transverse tension distribution model suitable for the continuous regression process is established, and the corresponding calculation strategy is given. Taking a continuous retreat unit of Baosteel stainless Steel Co., Ltd. As the research object, the original roll shape and the feed shape of the furnace roll are quantitatively analyzed. The influence of transverse temperature difference, flatness and perpendicularity error of furnace roll, setting tension and other factors on the transverse distribution of internal tension of strip during continuous regression, The corresponding software for predicting the transverse stress distribution and the shape evolution of strip in the process of continuous return unit is worked out and applied to production practice with good effect, which has the value of further popularization and application.
