1. Open from the furnace door-the trolley is driven out to the pool-the entire time of the trolley is tilted and the workpieces are all poured into the quenching pool is about 1 minute. The workpiece enters the quenching medium quickly, which improves the quality of heat treatment process.
2. The electric furnace heating temperature is controlled by PID zero-crossing triggering thyristor and high-precision intelligent meter. The temperature control accuracy is high, and the temperature difference fluctuates around ± 1 ℃. In addition, a circular chart automatic recorder is used to record the temperature and over-temperature alarms, and double control to ensure that the workpiece is not over-temperature during heating; the temperature is set according to the process.
3. The tilting of the trolley adopts electro-hydraulic device. The tilt of the trolley is stable without shaking, and the tilt angle is greater than 35 ℃.
4.The tilt of the trolley, the entry and exit of the trolley, and the lifting of the furnace door are all electrically controlled, and a chain protection device is provided to prevent malfunctions and accidents caused by misoperation.
5. No pollution, good environmental protection benefits.
