The outer shape of the hot air furnace is all rectangular, the task room is made of high quality carbon capsule filling machine silicon refractory material, the furnace shell is made of high quality cold rolled steel plate through the small particle machine, and the furnace and furnace shell are used as insulation layer with high quality insulation material. The muffle furnace is generally applicable to various laboratory, industrial and mining enterprises and scientific research units. The heat loss at the orifice improves the average temperature in the hearth of the hot blast stove. A heat shield made of high quality refractory materials is installed inside the door of the hot blast stove.
The hot air furnace does not have to assemble silicon carbon stick when changing the connection method. It only needs to change the connection method. And after changing the connection method, we should pay attention to the slow conditioning heating power conditioning button when using the muffle furnace. The value of heating current should not exceed the extra value.
If the chuck has serious oxidation, it should be changed. The slotting at the hole at both ends of the silicon carbon stick uses asbestos rope infarction. The furnace temperature of the resistance furnace shall not exceed the maximum task temperature of 1350. The silicon carbon V mixer rod is allowed to work for 4 hours at the lowest temperature. After a very long time in the hot blast furnace, the heating power adjustment is adjusted in clockwise direction. When the knob reaches its maximum position, the heating current will not go up. The extra value of the small labeling machine at intervals is far from the required heating power, which explains the aging of the silicon carbon rod.
Silicon carbon rod type furnace, when it is found that silicon carbon rod is damaged, should be replaced with a new silicon carbide rod with opposite and similar resistance values. First, remove the end maintenance cover and the silicon carbon stick, then remove the damaged silicon carbon stick, because the silicon carbon rod is broken easily, the device must be careful, the inner part of the exposed furnace shell should be equal, and the chuck must be fastened to silicon carbon. The rod is in good contact.
