美国设计产量增长公司推出线材轧机用的两种最新冷却运输带,可以显著提高高碳钢和合金钢线材的冶金性能。这两种运输带都是用不断运动的空气作为冷却媒介,一种运输带是链式的,另一种是辊式的。 在链式运输带上,是用管道把空气从现有的充气箱,引入离吐丝机区最近的头一段倾斜式运动带下面的喷气箱里。在此箱上有一系列借空气动力喷出凸圆气流的喷咀,把空气平行地引向一圈一圈移动着的线材近处,使周围空气从新形成的线圈中流过。从而在线圈离开吐丝机区后,立即得到迅速冷却,线材在短时间内离开倾斜段后
Increased Design Output in the United States The Company introduced two new cooling belts for wire rod mills to significantly improve the metallurgical properties of high carbon and alloy steel wire rods. Both conveyors use constantly moving air as the cooling medium, one for the chain and the other for the roll. On the chain conveyor belt, air is piped from the existing inflatable tank into the air box below the first sloping belt nearest the laying head. There are a series of nozzles on the tank for aerodynamically ejecting a convex stream of air, directing the air in parallel around a moving wire in a circle, causing ambient air to flow through the newly formed coil. Thus immediately after the coil exits the laying area, the wire is rapidly cooled. After the wire leaves the slanting section in a short time
