Does the box-type electric furnace need targeted maintenance?
box-type electric furnace is relatively common mechanical equipment. So do you know how to maintain this equipment that is more common? For maintenance, some users may think that there is no necessary reason. This is the 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 severely will cause ordinary box-type electric furnaces to malfunction. After understanding these, what should we do for box-type electric furnaces after daily use? How about maintaining and maintaining the box-type electric furnace? Let me explain it to everyone below
The box-type electric furnace is rectangular in shape. The task room is made of carbon capsule filled with silicon refractory material. The furnace shell is made of cold-rolled steel plate and welded by a small pellet machine. The furnace and the furnace shell are insulated by heat preservation 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.
Box-type electric furnace repair and maintenance
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 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 installing. The exposed inner part of the furnace shell at both ends should be equal. Tighten it to make good contact with the silicon carbide rod.
If the chuck is severely oxidized, it should be replaced with a new one. The gaps in 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 electric furnace has been used for a very long time, if the heating power adjustment button is adjusted clockwise, 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 box-type resistance furnace does not need to be assembled with silicon carbide rods when changing the connection method, only the connection method needs to be changed, 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.
