一、前言以前二辊、三辊或四辊轧机都是用辊颈支撑轧辊的轧机。为了得到宽度方向厚度均匀的成品,不得不磨削成具有能补偿轧辊挠度的凸度轧辊。尽管这个凸度量在研磨时可以选择一个合理的定值。严格说来,在轧辊的冷却条件相同的情况下,为了保持平行的轧辊间隙。则要求无论在那一道次上、轧件的宽度都是一样的,而且轧制力也必须是相同的。这样要求,在森吉米尔轧机上是很不方便的。因此,从日本引进的ZR——22BS——42型森吉米尔轧机上,有二种辊型调整装置。一种是用两套结构相同的传动机构,
First, the preamble Previously two rolls, three rolls or four-roll mill roll mill are used to support the roll mill. In order to obtain a finished product with a uniform thickness in the width direction, it has to be ground to have a crown roll capable of compensating the deflection of the roll. Although the convexity of the amount of grinding can choose a reasonable rating. Strictly speaking, in the case of the same cooling conditions of the rolls, in order to maintain a parallel roll gap. It is required that the width of the rolling stock be the same no matter at that one pass, and the rolling force must be the same. Such a request is very inconvenient on the Sendzimir mill. Therefore, from the introduction of Japan ZR - 22BS - 42 Sendzimir mill, there are two kinds of roll adjustment device. One is the use of two sets of the same transmission mechanism,
