炼铁厂75t行车的作用是将铸铁后的铁水罐进行渣铁处理和扣倒渣,并对罐内状况进行检查和调整罐位,保证铁水罐安全正常工作。行车扣倒作业原理是利用龙门钩挂套铁水罐的耳轴并将其吊起,再通过钢丝绳串入耳板小轴由副钩提升,使龙门钩轴瓦与铁水包耳轴相对磨擦完成倒渣作业。每次倒渣其龙门钩吊栽吨位>34t,磨擦力大,龙门钩轴瓦片和铁水罐耳轴磨损严重,目前铁水罐耳轴下半圆已平均磨损>22cm,最大量已有40cm,50天需更换2付龙门钩轴瓦片,使维修费用增加,也使铁水罐使用寿命缩短。
The role of the 75t ironworks is to iron cast iron after the iron slag iron slag processing and deduction of slag and tank conditions to check and adjust the tank to ensure the safe work of hot metal tank. Driving buckle operation principle is to use the gantry hook hanging sets of hot metal trunnion and lifting the trunnion, and then through the rope into the ear plate small shaft by the auxiliary hook to lift the gantry hook and shroud iron trunnion friction relative to complete the slag work . Each slag pouring gantry crane tonnage tonnage> 34t, friction, gantry hinges tiles and ladle trunnion wear serious, at present the lower half of the trunnion trumpet has an average wear of> 22cm, the maximum amount of 40cm, 50 days Need to be replaced 2 pay the door hook shaft tiles, so that maintenance costs increase, but also shorten the life of hot metal tank.
