High -temperature electric furnace of the molybdenum heating rod is an indispensable equipment for colleges and universities, research units, and industrial and mining enterprises. During the use, there are many places to pay attention to. Pay attention to these precautions and daily maintenance, which will make the high -temperature electric furnace furnace be a high -temperature electric furnace. The equipment is durable and accurate and accurate. Let me share with you the daily maintenance and operation of the high -temperature electric furnace:
For the first time, the furnace is not used for a long time. It should be baked for 1 hour at about 120 degrees, and it is used for 2 hours at about 300 degrees. So as not to cause the furnace to crack. The furnace temperature must not exceed the temperature, so as not to damage the heating element and the furnace lining.
It is forbidden to directly irrigate various liquids and dissolve into metals in the high -temperature electric furnace furnace of the silicon molybdenum rod to keep it clean in the furnace.
If the furnace body is used as a heating element with a silicon molybdenum rod, according to the physical characteristics of the silicon molybdenum rod, it is very brittle at room temperature. Therefore, it cannot be disassembled and moved at will after the heating element is installed.
When the cold furnace is used, because the furnace is cold, it must absorb a lot of heat, so the temperature increase rate of the low temperature section should not be too fast, and the temperature increase rate of the temperature should not be too large. When setting the heating rate, it should be fully considered. In order to avoid spray phenomenon, pollute the furnace.
Regularly check whether the contact part of the electrical connection part of the temperature control system is good, and pay special attention to whether the connection of each connection point of the heating original is tight.
When the silicon molybdenum rod is used as a heating element, it is not advisable to run for a long time at 400-700 degrees of silicon molybdenum rod high-temperature electric furnace, otherwise the silicon molybdenum rod will occur in low temperature oxidation.
If the heating element is damaged with more or the resistance value is too large, it is impossible to reach the required furnace temperature and all replace it into heart components.
During the work process, it is generally not eliminated if the control deviation of the control deviation is not eliminated at about 200 degrees to 300 degrees. The temperature -free display value and the procedure given value are inconsistent or excessive swing. Please check whether the parameter is accurate.
