Maintenance method of high temperature box furnace
The high-temperature box furnace is an electric furnace with a box-shaped shape and hearth. The workpiece in the box furnace is fixed during the entire heating process of the heat treatment experiment. Just open the furnace door, put the tools to be tested neatly in the middle of the furnace, and then close the furnace door. When taking the workpiece, the furnace door is also opened, the workpiece is taken out, and the furnace door is closed.
The box-type furnace has the advantages of high temperature accuracy and convenient operation. Mastering the maintenance methods of the box-type furnace can improve the efficiency of the electric furnace, save costs, and improve the economic benefits of the enterprise. Mastering the maintenance methods of high-temperature box-type furnaces can improve the service efficiency and life of electric furnaces. The following is a brief introduction to the maintenance methods of high-temperature box-type furnaces:
The temperature rise program of the box furnace has been programmed before leaving the factory, and the user operates according to the operation steps in the manual when using it. The box-type furnace will automatically heat up, but pay attention to observation during the heating process. If there is a temperature deviation, let the electric furnace run for a period of time to observe. If the deviation cannot be eliminated, or the deviation is too large or the temperature swings up and down too frequently, you need to Activate the auto-tuning function to assist in controlling the parameters. If it still doesn't work, you need to contact the manufacturer to solve it.
When using the box-type furnace, it is also necessary to pay attention to the fact that it is strictly forbidden to directly enter the furnace for heating treatment of workpieces containing high moisture, volatiles, organic matter, etc. At the same time, it is strictly forbidden to enter high-temperature molten materials such as metal and glass into the furnace for heating without crucible loading. It is necessary to check the condition of the heating element frequently. If aging, cracking or short circuit occurs, it should be repaired and replaced in time. And often remove the shavings, dust particles and scattered objects in the furnace to keep the furnace clean.
In short, the box-type furnace should be operated strictly according to the instruction manual, and the electric furnace should be cleaned and cleaned after use. The main reason is that the furnace must be cleaned, so as to ensure the quality of the workpiece in the next experiment.
