摘要:针对宣钢公司型棒厂连轧中型生产线工艺设备存在的问题分析了原因并进行了优化改造。通过
加粗翻转传动轴直径,并进行调质处理,加大旋转小车轴孔,改小车上下部分连接方式为过眼连接,加焊
可拆装挡钢角铁插槽,改变链条材质等对成排台架进行改造;对冷锯机的润滑油箱、减速箱轴承及控制
系统进行改造;同时将码垛机磁翻转油釭连接长轴改为一长一短两轴,升降液压缸位置编码改为接近开
关。改进后,弥补了原设计的不足,减少了设备故障停机,提高了生产作业率。

Abstract It is analyzed the reason for the problems in technological equipments in medium section continuous
rolling line in Sections and Bars Mill of Xuan Steel, and the optimization reformation is done against it. The
reformation consists of the following aspects improvements in rowing -up rack including: increasing the di
ameter of rolling -over drive shaft and quenching and tempering it, expanding axle hole of rotary car
change the connecting method of the car from upper and lower to hole connection, adding welded detachable
key way slotting of angle iron to stop steels, changing material quality of chain and etc. reformation in lubri
cation oil tank of cold saw, bearing of reduction gear box and its control system changing the long connect
ing axle of magnetic overturning oil tank of stacker into one long axle plus one short, changing location cod
ing of lifting hydraulic cylinder into proximity switch. After reformation it makes up for the deficiency in o
riginal design, reduces equipment breakdown and raises production rate
