推钢机设计
摘要
针对包钢高速线材厂加热炉推钢机运行可靠性差,工作部件磨损严重,维修与调整工作量大等问题,对原机械式传动推钢机进行了改造。重点介绍了液压推钢机的传动原理及在设计过程中需要注意控制的关键问题,对各主要零部件进行计算较核,最后提出了一套完整的操作规程和安装维修的方案。改造后的推钢机不仅满足了生产新产品的要求,且同步精度高、噪音低、振动小,同时还降低了能耗,提高了系统工作的可靠性,取得了很好的效果。

The Design Of Pusher
Abstract
Aiming at the poor running reliability, working parts heavy wear and large maintenance as well as so many adjustment etc. problems of ram of heating furnace in rolling plant of Shiheng Special Steel mechanival driving ram has been revamped. Driving mechanism of hydraulic ram and the crucial questions to be control in design are emphatically introduced, it can be used for reference in same industry beating furnace. Carry out the directive rules calculating the operation being more entire than having examined, having brought forward the same stuff finally on every ponent and part and assemble the scheme being maintained. The transtormed pusher can satisty the needs of products with its high synchro precision, low-noise and vibration, reduce energy consumption and increase reliability of the hydraulic system, and good result has been gotten.
Keywords: Heating furnace Ram; pusher; Hydraulic system; Reliability; Secunity
