一、前言随着机车车辆的重载和高速化,为了提高车轮的强度和耐磨性,踏面采用淬火和回火的所谓“踏面热处理”车轮的需要量在不断地增加。与此同时,日本住友金属公司车轮工厂的热处理炉也在逐渐加强,目前已达到每月能处理约23000个车轮的能力。但是,由于这些设备是以弥补其能力不足而增设的,所以作为生产线来说,还存在着很多的缺点。就是说,小容量的台 I. INTRODUCTION With the overloading and speeding of locomotives and rolling stock, the so-called “tread heat treatment” wheels with treads and tempering are continually increasing in order to increase the strength and wear resistance of the wheels. At the same time, Japan’s Sumitomo Metal’s wheel plant heat treatment furnace is also gradually strengthened, has reached the monthly capacity of about 23,000 wheels. However, since these devices are added to make up for their lack of capacity, there are still many drawbacks as a production line. That is to say, a small capacity of Taiwan
