一、前言热轧厂主体设备成套由日本引进。粗轧机R_1～R_4主传动轴传动侧和工作侧半圆滑块万向接轴原设计为自动敞开式给油,油经滑块润滑后流入地沟(R_2传动侧例外),每天耗油1451升,这种结构不仅浪费大,而且油排入地沟,污染水质,而且加油量如此之大,给维护工人带来很重的负担。除此之外R_3和R_4轧机相对R_1和R_2轧机 First, the preface Hot rolling mill main equipment complete sets of equipment imported from Japan. Roughing machine R_1 ~ R_4 main drive shaft and the work side of the semicircle slider universal joint shaft is designed to open automatically to the oil, the oil flow through the slider into the trench (R_2 transmission side exception), daily fuel consumption of 1451 liters, Such a structure is not only wasted, but also oil is drained into the ditches to pollute the water quality and the amount of refueling is so great that a heavy burden is placed on maintenance workers. In addition to the R_3 and R_4 rolling mill R_1 and R_2 rolling mill
