1 前言众所周知,历来工业上轧制通用的概念是轧件咬入辊缝时受极限咬入角和每一道次压下量等基本条件所限制(以下对此称普通轧制)。本文作者进而研究了超出咬入极限范围的轧制过程。对于这一领域的轧制早在1927年就有 H.Sedlaczek的理论研究,提出了咬入时接触角可能达到极限咬入角二倍的轧制理论,但以后并没有夫于这方面的详细报导。作者的研究是靠外加推力解决咬入极限问题并采取最大断面收缩率的轧制的一部分(以
1 Preface As we all know, the concept of the industry has always been rolling common bite into the roll gap by the limit biting angle and the amount of each pass reduction and other basic conditions (hereinafter referred to as ordinary rolling). The authors then investigated the rolling process beyond the bite-in limit. For the rolling in this area, as early as 1927, there was a theoretical study by H. Sedlaczek, which proposed a rolling theory that the contact angle may reach twice the limit bite angle when bite in, but there is no detailed description in this respect Reported. The author’s study is based on the application of thrust to solve the problem of bite-in and to take part in the rolling with maximum reduction of area
