摘要
立輥軋機是用來從側(cè)面對帶鋼進行軋制，從而使帶鋼保持一定的寬度和側(cè)邊質(zhì)量，同時也起一定的破磷作用。
此次設(shè)計的立輥軋機采用了上傳動框架式結(jié)構(gòu)。和懸臂式立輥軋機箱比較，框架式立輥軋機具有受力情況良好、設(shè)備使用壽命較高、設(shè)備的剛度較高的優(yōu)點。故較大型的立輥軋機多采用框架式結(jié)構(gòu)。本文以服務(wù)生產(chǎn)為目的，在軋制技術(shù)經(jīng)典理論的基礎(chǔ)上，結(jié)合現(xiàn)場工藝和實際數(shù)據(jù)，利用機械設(shè)計的理論，力圖擺脫原來粗軋立輥的缺點，改進熱軋粗軋機結(jié)構(gòu)設(shè)計，從而軋機的可靠性和工藝性。主要包括以下內(nèi)容：
⑴ 機架的改進
⑵ 測壓下的改進
⑶ 檢修平臺的設(shè)計
⑷ 主傳動的改進

Title  The design of the vertical mill

Abstract
The edger vertical mill is used to proceed stranding the strip steel from the side, making the strip steel keep the certain width and quality, also rises to break the scale action certainly.
  The edger vertical mill of this time design adopted the last transmission
frame type construction. The frame type edger vertical mill has, compares
than the sum cantilever type edger vertical mill, the good circumstance
of the equipment. So many of the large vertical mill adopts frame type
construction. The thesis, basing on classical rolling theory and combining
with the data from actual process, aims at serving the actual production.
It does′t depend on the weakness of the rough edging mills to determine
the reliability of the stranding machine and craft and to improve the
hot tandem rolling roughing-cown rolls construction design. Primarily
including contents bellow:
⑴The improvement of the stand
⑵The improvement that side press down
⑶The design of the fixs platen
⑷The improvement of the main transmission

Keywords  vertical edger    hot-strip     reliability
technique of rolling
