出钢机的设计
摘  要
出钢机是加热炉区重要的机械设备之一，它的运转直接影响整套轧机的生产率。目前广泛应用的出钢

机有两种，分别是侧出料出钢机和料杆式出钢机。本文对料杆式出钢机进行了研究，并根据现场的环

境设计了料杆式出钢机。
首先本文讨论了出钢机的发展及主要形式，并阐述了料杆式出钢机的工作原理及工作过程。在设计过

程中，对主要的部件做了合理的选用，例如：传动系统设计中电动机及减速器的计算和选用、联轴器

的选择、出料杆升降机构和移送机构的方案进行的论证等等，以便达到最佳的经济效益和工作效率。
然后根据原始数据中的出料杆前进和后退的速度，计算传动轴的转速和电动机至出料杆的总的机械传

动效率等结果，并依据这些结果初选电动机，并对所选电动机做过载校核，若满足要求则选用，否则

重新选用再校核。再选择联轴器、设计减速器并选用。
最后对主要零件进行强度校核，包括出料杆、压辊和传动轴进行强度校核，联轴器的强度校核，减速

器中齿轮、轴和轴承的强度校核，传动轴上键的强度校核。

关键词：出料杆 ，移送机构，压辊

A steel aircraft design
Abstract
Heating furnace steel machine is a mechanical one important area, which directly affects

the functioning of the entire rolling mill productivity. The current widespread

application of the two steel, a material difference is adjacent to a steel machines and

materials from foreign steel machines. All of the expected foreign steel machines

studied, and in accordance with the environmental design of the expected foreign steel

machines.
The first discussed a steel aircraft development and main form of foreign steel

materials and expounded principles and the work process. In the design process, the main

components of a reasonable choice, for example : drivetrain system design, calculation

and electric motors and reducer selection, shaft coupling option, the expected pole-

transfer agencies and institutions of verification programme, in order to achieve the

best value for money and efficiency.
Based on raw data from the expected pole speed of the advance and retreat, on the

transmission shaft rotational speed and electric motors to a total expected pole

mechanical transmission efficiency results, and based on these findings primary electric

motors and electric motors done is chosen degree, if it is to meet the requirements of

the selection, otherwise choose to re-verification. Then shaft coupling, reducer design

and selection.
Finally intensity of the main components for verification, including the expected pole,

pressure roller intensity and transmission shaft for accuracy, shaft coupling degree of

intensity, reducer, gear, axle and bearings intensity accuracy, transmission shaft, Kin

intensity degree.
