小方坯连铸机热送辊道系统稳定性的研究

Research on the Stability of Hot Charging Roller Table System for Billet Caster

针对小方坯连铸机热送辊道使用中出现冷装区辊子轴承损坏、热送区减速机摆动和打齿、辊子窜动等情况，对冷却润滑方式、传动形式、辊子轴承形式等进行了相应的改造，提高了热送设备的稳定性，提升了设备使用寿命，降低了备件成本。

The hot charging roller tables of the billet caster occur damage on the roller bearing of cold charging zone, swing in the reducer of hot charging zone, tooth breaking and roller shift in operation. Make a modification on the cooling lubrication method, drive mode and roller bearing type. Therefore, the stability of hot charging device and the service lifetime of equipment are improved, and the spare parts cost is decreased.
