摘要
為克服普通壓力矯直機效率低，質(zhì)量差的缺點，適應(yīng)連續(xù)生產(chǎn)的需要，本課題研

制了高速連續(xù)工作的7 600輥式型鋼矯直機。
此矯直機的用途是矯直20#槽鋼。它的輥子上加了與被矯件斷面相對應(yīng)的孔型

。本矯直機為開式矯直機，輥子為懸臂式布置。固此操作時易于觀察。且換輥方

便。
矯直工藝采取是上排工作輥單獨調(diào)整的矯直工藝。第二、三輥按照大變形量

確定其壓下量，將軋件劇烈彎曲。第四輥壓下量適當(dāng)控制，使殘余曲率值減小，

后面各輥按小變形法調(diào)整壓下量，使軋件逐漸矯平。軸承選用雙列向心滾子軸承

以實現(xiàn)軸的調(diào)整來對正孔型。

Abstract
To overcome shortcomings of bittle efficiecy and bad quality during

the ordinary pressure straightening machine works and to adapt needs

of quality of successive production ,7x600 rollmodel shape

straightening machine has developed in this subject.
Use of this machine is to ing 20# channel steel .The passes are

installed on the rolls and contrasted the seetion of straightened

shape.This shape straightening machine is a open style machine and

straightening rolls are arranged by cantilever style.So it is

subjected to observe operating process and changing rolls is very

convenient.As long as chaning passes,shorts of shape are straightened.
Upper,Line work rolls adjusted lonely isadopted in straightening craft

.Reductions capacity of the second roll and third are determined by

big deformation
Capacity .So rolled stell is crooked fiercely .Then reductions of

fourth roll are controlled properly to reduce remains curature value

and reductions of all back rolls are adjusted by small deformation

capacity.Lastly ,the thrust ball bearing is selected to finish axial

adjustment and passes are aimed at.
