The application of leveling furnaces is becoming more widespread. During long-term operation, vacuum furnaces may experience component failure and damage, leading to a decrease in mechanical operational capacity. To ensure the normal operation of leveling furnaces and extend the service life of vacuum furnaces,

Based on the programmable logic controller program for pumping the leveling furnace: Close all vacuum valves, start the mechanical pump, and once it is operating normally, open the low vacuum valve leading to the furnace body, known as the top disk valve, of the Xi'an annealing leveling furnace model, and pre-pump low vacuum into the furnace.

The maintenance of the leveling furnace should guide the equipment operators to perform daily maintenance according to the inspection cycle within their responsibility scope, using the correct inspection methods and tools. Operators should fill out the daily maintenance records of the heat treatment equipment meticulously as per the maintenance instructions daily, which will then be reviewed and approved by the team leader. The maintenance personnel will collect and archive these records.
