Semi Plate Spring Oscillation Device

1. Low energy consumption 2. High efficiency 3.Ingenious design 4.Low vibration noise

The oscillation device is of a semi plate spring type, and consists of the oscillation stand, supporting seat, connection rod, motor, and reducing gear. The motor drives the push rod to make a sine-wave oscillation. The motor is equipped with eccentric gear. The oscillation device should be installed at the correct station. Sine-wave movement has the advantages of steady speed change, shock freeness, and negative slip. Osicllation of the crystallizer effectively prevents billet ripping caused by felting of fresh billets and crystallizer, therefore, having a mold-unloading function. The worker should choose the right swing and frequency for the oscillation device. It is proved by relevant experiments that high-frequency and low-swing oscillation effectively reduces oscillation marks on the billet surface and billet cracks.

Before running the oscillation device, the ventilation cap should be loosened or replaced by a new one to assure smooth ventilation of the reducing gear and motor. The lubrication oil level should also be checked before running.

At test-running, the oscillation device should test-run oil-free for half an hour, and then could run with oil for daily performance when the oil-free test-running is successful. The oil temperature rise, sealing, and noise should be closely monitored when the oscillation device is  working. When the oscillation device runs for 2 hours, the oil temperatuer rise should be within 45°C-60°C. The lubrication oil grade should be within N220-N320. When the oscillation device runs for a month (about 200-300 hours), it should be cleaned, and the lubrication oil should be replaced. After first cleaning, the lubrication oil should be replaced half a year, and in the meantime, the oil level should be closely monitored at running.(The maintenance of the reducing gear is similar to this passage.)
