大钟拉杆是高炉设备中主要零件之一。某些工厂曾发生过大钟拉杆被顶弯的严重事故,造成重大损失。大钟拉杆的顶弯多发生在大钟强迫下降、且大钟与拉杆用楔连接的高炉上。有人认为大钟拉杆顶弯完全是由于料钟强迫下降方式造成,应把强迫下降改为自由下降,这样即使某些设备有缺陷和操作规程执行不严时,也不致发生大钟拉杆顶弯事故。有的厂已把大钟 Bell pull rod is one of the main parts of the blast furnace equipment. In some factories, a serious accident occurred when the bell lever was bent over, causing heavy losses. The bending of the bell of the big bell occurred in the bell forced to drop, and the bell and the bar connected with the wedge on the blast furnace. Some people think that the bell crank bending is entirely due to the material bell forced to fall caused by the forced decline should be changed to free fall, so that even if some of the equipment is defective and poor implementation of the rules, it will not happen bell strike bending accident .
