发明名称 METHOD OF MAKING CAST STEEL RAILWAY WHEELS AND COOLING TUNNEL FOR COOLING SUCH VHEELS
摘要 The present invention provides a method of producing cast steel railway wheels. After pouring and removal from the mold, the steel wheel is processed in various steps including processing in an annealing and a tempering furnace. The wheel is then passed through a wheel cooling tunnel where the wheel is cooled from approximately 900 DEG F. to about ambient temperature.
