Frit furnace maintenance work

Frit furnace is relatively common mechanical equipment. So do you know how to maintain this equipment that is more common? Some users may think that there is no reason for maintenance. This is a wrong idea. Regardless of any equipment, there is regular maintenance. If we do not do a good job of regular maintenance, the use cycle of equipment and instruments will be greatly shortened, and serious problems will be caused. After understanding this, what should we do to maintain and maintain the electric furnace after daily use? Let me explain it to everyone

The outer shape of the clinker furnace is rectangular parallelepiped. The task room is made of carbon capsule filled silicon refractory material. The furnace shell is made of cold-rolled steel sheet and welded by a small pellet machine. The furnace and the furnace shell are insulated by insulation materials. Floor. Box furnaces are generally applicable to various laboratories, industrial and mining enterprises, and scientific research units. In order to increase the heat loss at the furnace mouth and improve the average temperature in the furnace, a heat shield made of refractory materials is installed on the inside of the furnace door.

silicon carbide rod type furnace, if the silicon carbide rod is found to be damaged, it should be replaced with a new silicon carbide rod with the opposite specification and similar resistance value. When changing, first remove the maintenance cover and the silicon carbide rod chuck at both ends, and then take out the damaged silicon carbide rod. Since the silicon carbide rod is fragile, be careful when setting up the furnace shell. The chuck must be tightened so that it is in good contact with the silicon carbide rod.

If the chuck is severely oxidized, it should be replaced with a new one. The gaps at the device holes at both ends of the silicon carbide rods are blocked with asbestos rope. The furnace temperature shall not exceed the highest task temperature of 1350℃. The silicon-carbon V-type mixer rod is allowed to work continuously for 4 hours at the lowest temperature. After the frit furnace has been used for a very long time, if the heating power is adjusted clockwise to the maximum position, the heating current will still not rise. The extra value of the small labeling machine is far away, and the required heating power is not reached, which explains the aging of the silicon carbide rod.

The high temperature frit furnace does not need to be assembled with silicon carbide rods when changing the connection method, just change the connection method, and after the connection method is changed, pay attention to the slow adjustment of the heating power adjustment button when using the muffle furnace, and the heating current value must not exceed the additional value.
